    Flower color and fragrance are important traits that give ornamental plants their value. The synergistic combination of flower color and scent attracts pollinators with specific preferences. In this study, we discuss the connection between biosynthetic pathways leading to color and scent in flowers. Pigments and scent compounds in flowers vary in phenol and terpene contents, providing many combinations of color and scent. Many floral pigments and scent compounds share the same biosynthetic pathways, including the shikimate (SA), methylerythritol 4-phosphate (MEP), and mevalonate (MVA) pathways. In addition to reviewing the biosynthesis, functions, and changes in floral color and scent in relation to abiotic factors, we suggest a novel schematic diagram of the shared biosynthetic pathways in flowering plants for floral pigments and scent compounds classified as phenolics and terpenes. Although more information is still needed, it seems clear that the color and scent of flowers have a biochemical connection and are a selective choice. Therefore, a comprehensive understanding of the biochemical linkage between the color and fragrance of flowers is critical for developing new varieties with novel traits. - COLLAPSE

    This study determined the optimal growing degree days (GDD) and cultivars of Kimchi cabbage (Brassica rapa L. ssp. pekinensis) for growth and yield during spring cultivation under shading condition. There were nine treatments, and the experiments were conducted with three GDD levels (899, 924, and 961) and three cultivars (‘Chungwang’, ‘Cheongna’, and ‘Cheongok’) under shading conditions. The process-based model of Kimchi cabbage was applied for growth and yield prediction using meteorological data regarding light, temperature, wind, precipitation, and humidity in several regions. The number of leaves of ‘Chungwang’ Kimchi cabbage was greater than that of ‘Cheongna’ and ‘Choengok’ at all planting times. Most of the growth parameters were highest in the delayed transplanting treatment than in the other transplanting times. ‘Chungwang’ Kimchi cabbage was less sensitive to high temperature during spring cultivation than the other cultivars. GDD 924 was the most optimal time to harvest under the shading condition. GDD 750-870 is considered an appropriate harvest time in the primary production regions during the spring cultivation season. If shading is performed in these regions, constant production may be possible, thus, alleviating damage from high temperature. - COLLAPSE

    In this study, the influence of nitrogen (N) and phosphorus (P) rates on plant growth, flowering, and uptake of essential nutrients was evaluated in container-grown tall bearded (TB) iris (Iris germanica) ‘Immortality’. Factorial combinations of three N (5, 10, or 15 mM) rates and three P (5, 10, or 15 mM) rates were applied to plants via fertigation twice per week from March to September 2013. Plant height, leaf SPAD reading, and flowering data were collected during the growing season. Plants were harvested in December 2013 to measure dry weight (DW) and analyze concentrations of essential mineral elements. Greater N rates had positive effects on plant height, leaf SPAD reading, flowering performance, and uptake of several essential elements, such as potassium (K), calcium (Ca), and iron (Fe). Phosphorous rate did not significantly affect most of the growth parameters. Greater P rates increased P concentration in leaves and roots and decreased boron (B) concentration in leaves but did not significantly influence net uptake of other nutrients except copper (Cu). The average N:P ratio ranged from 4.7 to 7.5, 2.4 to 4.0, and 6.0 to 8.7 in leaves, roots, and rhizomes, respectively. - COLLAPSE

    Tipburn occurs occasionally in Kimchi cabbage, and lowers quality and yield. This study was carried out to understand the causes and reduce the occurrence of tipburn. Daily calcium uptake increased rapidly at the heading time when Kimchi cabbage biomass increased. Tipburn occurred when Kimchi cabbage was hydroponically cultured for over 24 hours in calcium-deficient nutrient solution, and occurred on leaves ranging from the 20th to 50th leaf from the outer leaf. Calcium content was lower in inner leaves than in outer leaves, and was lower at the leaf margins than in the middle part of the leaf. Tipburn was more sensitive to soil drying than to saturated soil. In the 70/100% day/night relative humidity (RH) treatment, tipburn did not occur at all, and in the 50/100% RH treatment, it appeared mildly at the initial stage and recovered. In the 40/80% RH treatment, in which the RH was kept low during the day, tipburn occurred severely, and in the 20/40% RH treatment, in which the RH was kept very low during the day and night, the leaves were shriveled, but tipburn did not occur. It seems that the occurrence of calcium deficiency can be reduced by increasing the humidity at night while managing sufficient soil moisture in highland Kimchi cabbage.


    빈번히 발생하는 칼슘 부족에 따른 생리 장해의 발생은 품질과 수량을 현저히 떨어 뜨린다. 본 연구는 팁번 발생을 경감시키기 위한 기초 자료를 얻기 위하여 수행되었다. 배추의 일중 칼슘 흡수량은 배추의 생체량이 급격하게 증가하는 결구 초기에 증가하는 경향을 보였다. 24시간 이상의 양액 내 칼슘을 결제처리할 할 경우, 대부분 팁번이 발생하였으며, 나타나는 부위는 외엽으로부터 20-55엽위에서 발생하였다. 구 내엽의 칼슘의 함량은 외엽에 비해 매우 낮았으며, 잎의 중앙부위보다는 잎 끝 부위에서 낮았다. 칼슘 결핍은 토양과습보다는 토양 건조에 민감하게 반응하였다. 주/야간 70/100% 습도처리에서는 팁번이 전혀 발생하지 않았으며, 50/100% 습도 처리에서는 초기에 가볍게 나타났다가 회복되었다. 주야간 낮게 유지하였던 40/80% 습도처리에서는 팁번 발생이 심하였으며, 주야간 매우 낮게 유지되었던 20/40% 습도처리에서는 잎이 위축될 뿐 팁번으로 진행되지는 못하였다. 고랭지배추 재배 시 토양수분이 부족하지 않도록 관리하면서 야간 습도를 높이면 칼슘 결핍증 발생을 줄일 수 있을 것으로 보인다.

    In the climate of Korea, it is difficult to maintain consistent year-round production of cut roses in greenhouses because of high temperature in summer and low radiation in winter. Therefore, it is important to determine the optimal growing conditions by analyzing the effect of seasonal environmental changes in greenhouses on the growth of cut roses. In this study, a model for rose shoot growth developed by a previous study was validated and modified. The results of the experiment showed that the model had a high coefficient of determination for growth of shoots and performed well for predicting the growth in four cultivars of cut roses: Rosa ‘Antique Curl’, R. ‘Beast’, R. ‘Ahoi’, and R. ‘Fuego’ (R2 = 0.84, 0.87, 0.79, and 0.90, respectively). However, at the harvest stage, the model over- and under-performed, respectively, for the cultivars ‘Antique Curl’ and ‘Fuego’. The maximum leaf area coefficient of the leaf area equation was modified to take into account the leaf area of cultivars ’Antique Curl’ and ’Fuego’. Re-experimentation showed that the modification improved the performance of the model for both cultivars while maintaining the high coefficient of determination. The growth model developed by the previous study is applicable for greenhouse production of cut roses in Korea. Therefore, this shoot growth model may be used to aid growers in maintaining the optimal growing environment within greenhouses and to provide base data for greenhouse environmental control and monitoring systems. - COLLAPSE

    The aims of this study were to analyze dynamic stem elongation of standard cut-chrysanthemum (Dendranthema grandiflorum) with different photoperiod levels. Standard cut-chrysanthemum cv. Baekma was grown at a 16 hr photoperiod until 23 days after planting, after that different photoperiods of 8, 10, 12, 14, and 16 hr (8H, 10H, 12H, 14H, 16H) were applied using fluorescent lights in a plant factory. The long-day treatments of 14H and 16H produced no flower buds and the 8H treatment was significantly delayed in flower budding initiation compared to the 10H or 12H treatments. The final characteristics of plant height, plant fresh weight, and number of internodes in the 14H and 16H treatments were significantly higher than in the other treatments. Plant height was significantly fitted with parameters of maximum stem length (yasm), relative stem elongation rate (k), and days to reach maximum stem elongation rate (tinf) in the Gompertz growth model as a function of days after planting. As the photoperiod increased longer than 14H, yasm was continuously increased, tinf was delayed in the 12H-16H treatments, and k was increased between the 8H and 12H treatments and decreased with long day treatments. The maximum stem elongation rate (MGR) was 1.15 cm·d-1 in the 12H treatment, which was the highest stem elongation rate. Plant height and days after planting were translated to relative scales from 0 to 1 and 0 to 1 or 2 respectively. Relative stem length was significantly fitted and described 99% of relative plant height to developmental stage (DVS) with three parameters of maximum relative stem length (yasm.DVS), relative stem elongation length (kDVS), and days to reach maximum relative stem elongation rate (tinf.DVS) in the adjusted Gompertz growth model. yasm.DVS was no differences between 8H and 12H in short days whereas 14H and 16H were estimated to be 1 and compared to 12H 22% higher at long day treatment. kDVS was higher in the 14H and 16H treatments than in the 12H treatment, which means the long-day treatment increased growth rapidly to different DVS. tinf.DVS was estimated to be between 1.143 and 1.224 in the short day treatment and showed the maximum relative growth rate. Maximum growth ratio to DVS was 68% of plant height in 8H, 10H and 12H whereas 14 and 16H were 62% and 63% of plant height reached at tinf.DVS. Our study suggested that the Gompertz growth model can describe and summarize the dynamic stem elongation pattern of standard cut chrysanthemum ‘Baekma’ and it is advisable to use a 14H photoperiod in long-day conditions and a 12H photoperiod in short-day conditions during the cultivation of ‘Baekma’.


    본 연구는 일장수준에 따른 스탠다드 절화국화의 다이내믹한 초장의 변화과정을 Gompertz 생장 모델을 이용해 분석하고 처리간 생장에 관여하는 파라미터를 비교하였다. 스탠다드 절화국화(Dendranthema grandiflorum) ‘백마’는 정식 후 23일까지는 일장을 16시간 처리 이후, 일장의 길이를 8, 10, 12, 14, 16시간(H)으로 달리 처리 완전 밀폐된 식물공장에서 재배하였다. 일장처리에 사용한 광원은 형광등을 이용하였다. 12H 이하의 일장에서의 평균 출뢰소요일이 단일 처리 후 49일에서 59일로 8H 처리구에서 가장 지연되었고, 14시간 이상의 장일조건에서는 출뢰되지 않았다. 정식 후 일수에 따른 초장은 Gompertz 생장모델의 최대줄기신장량(yasm,cm), 상대줄기신장율(k, d-1), 최대줄기신장율에 도달하는 정식 후 일수(tinf,d)를 이용하여 유의적으로 측정값의 98%이상 묘사하였다. yasm는 12H 이하의 조건에서는 유의한 차이가 없었으며, 장일조건인 14H과 16H 처리구에서는 가장 높았다. tinf는 12H 이하에서는 정식 후 28일에 최대신장율에 도달하였으며, 12H 이상에서는 일장이 길어질수록 지연되었다. k은 8H-12H 처리구간에서는 일장에 따라 증가하였으며, 12H 이상에서 일장에 따라 감소하였다. 최대 줄기 신장율(MGR)은 12H처리구에서 1.15cm·d-1로 가장 높았다. 발육단계에 따른 상대 초장은 변환된 Gompertz 생장모델의 매개변수 최대상대줄기신장량(yasm.DVS), 상대줄기상대신장량(kDVS), 최대상대줄기신장율에 도달하는 DVS(tinf.DVS)를 이용하여 99% 이상 유의적으로 묘사할 수 있었다. yasm.DVS는 8H-12H 단일처리구에서는 범위는 0.014로 큰 차이를 보이지 않았고, 14H와 16H 처리구는 1을 나타내 12H 처리구에 비해 22% 높았다. kDVS은 14H와 16H 처리구에서 12H 처리구에 비해 곡선의 변화가 급격하였으며 tinf.DVS는 12H 이하의 단일 처리구에서는 1.143-1.224 DVS로 단일처리 이후의 최대 상대 생장율을 나타냈다. 최대 상대 생장율지수에 도달시 12H 이하의 단일처리구에서는 상대 초장의 길이는 전체 길이의 68%, 14H과 16H 처리구에서는 총 각각 62%와 63%에 도달하였다. 본 연구 결과 Gompertz 생장모델은 스탠다드 국화 ‘백마’의 다이내믹한 초장 신장패턴을 해석하고 요약할 수 있는 도구로 사용될 수 있었으며, 초장의 다이내믹 신장율을 고려한 재배기간 중 ‘백마’의 장일처리시간은 14시간이상, 단일처리시간은 12시간을 유지하는 것이 적합한 것으로 생각된다.

    We investigated quality changes during storage in white peach (Prunus persica (L.) Batsch; cv. ‘Mibaekdo’) and yellow peach (cv. ‘Janghowon Hwangdo’) to estimate single and combined effects of hydrocooling and 1-methylcyclopropene (1-MCP) treatment to extend shelf life. Fruit at the optimum maturity with green background 60 ± 10% were harvested and subjected to hydrocooling by immersing fruit into a water tank generating micro-bubbles for 40 min at 0℃ and/or a 3 µl·L-1 of 1-MCP treatment for 12 hrs, followed by storage at 10℃. In both cultivars, ethylene production was lowest from fruits treated with 1-MCP and hydrocooling (combined treatment) compared to the individual treatments as well as control fruit throughout storage. The firmness of the control fruit decreased rapidly from about 35 N at harvest to about 8 N on the 8th day of storage, but fruit in the combined treatment remained much firmer for at least 4 days after treatment. Total soluble solids content was also significantly higher at least 4 days after treatment in ‘Mibaekdo’ fruit applied with the combined treatment, whereas ‘Janghowon Hwangdo’ fruit did not display an obvious positive effect by the combined treatment. The titratable acidity of the ‘Mibaekdo’ fruit was also lower in the combined treatment, whereas ‘Janghowon Hwangdo’ showed similar levels among treatments. Removal of trichomes from peach fruit by micro-bubbled hydrocooling can also enhance the marketability of the fruit by eliminating allergy-like responses from customers to the fruit. The results obtained in the present study suggest that hydrocooling followed by 1-MCP application to peach fruit maintains firmer flesh and extends the shelf-life by at least 4 days, therein improving marketability. - COLLAPSE

    Wax apple is one of the most important commercially grown fruits and is consumed worldwide due to its excellent quality attributes and high degree of acceptance by consumers. However, wax apple is highly perishable and the application of storage and other postharvest technologies is necessary to maintain fruit quality from harvest to consumption. In this study, the effects of sodium nitroprusside (SNP) on the postharvest quality and senescence of wax apple (Syzygium samarangense (Blume) Merr. & Perry) was investigated. The wax apples were treated with three concentrations of SNP (1, 2.5, and 5 µmol·L-1), and the control was treated with distilled water. The treated fruits were air dried naturally and stored at 25°C (the relative humidity was 90%) for 7 days to determine the various parameters. The results demonstrated that soaking in SNP maintained higher titratable acidity (TA) and soluble solids content (SSC) and sustained a stable Brix-acid ratio (BAR). SNP also suppressed the degradation of anthocyanins and the decrease of firmness. Additionally, it functioned in delayed polyphenol oxidase (PPO) and peroxidase (POD) activities in the early period and suppressed the decrease of the two enzyme activities in the late period. Increases in malondialdehyde (MDA) content were inhibited. In summary, 2.5 µmol·L-1 SNP significantly maintained the quality and suppressed the senescence of postharvest wax apple fruit compared to the control. Therefore, the application of SNP may represent a promising and practical methodology for extending the shelf life of fruit. - COLLAPSE

    Plasma-membrane intrinsic proteins (PIPs) play important regulatory roles in plant growth and development, and in the maintenance of water homeostasis under stress conditions. To investigate the function of SlPIP1;7 in tomato (Solanum lycopersicum) plants, we created transgenic tomato lines in which the SlPIP1;7 gene was overexpressed or silenced. SlPIP1;7-overexpressing and SlPIP1;7-silenced plants were taller and shorter than wild-type plants, respectively. Additionally, silenced lines had a significantly narrower stem diameter than wild-type plants and severely retarded shoot and root growth, suggesting that overexpression of SlPIP1;7 enhances tomato growth. Moreover, SlPIP1;7-overexpressing plants exhibited increased salt stress tolerance, while SlPIP1;7-silenced plants were more sensitive to salt stress. SlPIP1;7-overexpressing plants showed a higher photosynthetic rate and root hydraulic conductivity, less electrolyte leakage, and less malondialdehyde and reactive oxygen species accumulation under salt stress compared to the wild-type; SlPIP1;7- silenced plants showed the opposite tendencies. These results suggest that overexpression of SlPIP1;7 promotes photosynthetic efficiency, root water uptake, and antioxidant defense in plants under salt stress, thereby imparting salt tolerance. SlPIP1;7 is thus a valuable genetic resource to enhance stress tolerance in tomato plants. - COLLAPSE

    Gametophytic self-incompatibility, one of the key characteristics for breeding seedless Citrus cultivars, occurs in pummelo (Citrus maxima), mandarin (Citrus reticulata), and their hybrid cultivars. Allelic variation in Citrus was reported for the self-incompatibility gene (S); however, S allele frequencies and S genotypes of full- and semi-self-incompatible cultivars have been reported for a small number of alleles. To extend our knowledge of S alleles, we tested 146 Citrus accessions, including 82 pummelo accessions, for S9 and S10 alleles. Each accession was pollinated with homozygous S1 seedlings of ‘Hirado Buntan’ pummelo (S9S9 and S10S10). The pollen tube growth arrest in the lower styles of their pollinated pistils indicated that four accessions, including ‘Hirado Buntan [Citrus maxima (Burm.) Merr.]’, have the S9 allele and five accessions, including ‘Hirado Buntan’, have the S10 allele. The percentage of accessions with the S9 allele was 3.2% (4 of 126 accessions examined), and the S9 allele frequency was 1.8% (4 of 217 alleles, excluding the Sf allele). The percentage of accessions with the S10 allele was 3.9% (5 of 127 accessions examined), and the S10 allele frequency was 2.3% (5 of 217 alleles, excluding the Sf allele). Japanese mandarin (another sources of S alleles) and its relatives had neither the S9 nor the S10 allele. Pummelo accessions had S9 and S10 alleles at higher rates of 2.9% (2 of 70 accessions examined) and 7.0% (5 of 71 accessions examined), respectively. ‘Kabusu’ sour orange (a pummelo-mandarin hybrid; Citrus aurantium) and ‘Kikudaidai’ (a sour orange relative; Citrus canaliculata) had S9 alleles. These results suggested that the two alleles originated from pummelo (the main sources of S alleles). The S genotypes with S9 and/or S10 alleles were fully determined in ‘Hirado Buntan’ (S9S10), ‘Kabusu’ sour orange (SfS9), the ‘Kikudaidai’ (S9S11) sour orange hybrid, and two local pummelo plants. The results of our study suggest that in comparison with the other S alleles reported, the pummelo plants with low frequencies of S9 and/or S10 alleles contributed to very low rates of evolution and development of Citrus species and cultivars during the long history of citrus cultivation, except for those generating sour oranges (Citrus auratinum), which are used as root stocks, and for flesh and rind processing and ornamental plants. Finally, we examined the degree of self-incompatibility between S9 and S10 alleles in the lower part of styles of S1 seedlings of ‘Hirado Buntan’ and Citrus accessions with S9 and/or S10 alleles. The result indicated no difference in the self-incompatibility reaction between the two alleles. - COLLAPSE

    Akebia trifoliata, commonly named augmelon (means August plus melon), has been domesticating as a new artificial cultivation fruit crop in China for several years. Generally, field management measurements are severely dependent on the development dynamic of harvest organs, and therefore the study of fruit development stage of A. trifoliata is urgent in production. In this study, four cloned lines with various spindle, nephroid, pyriform and Banana-like shapes, were selected to observe fruit developmental parameters, including volume, weight, length and width from pollination to maturity. Volume rather than length or width, which can minimize the influence of fruit shape on growth stage, was finally employed as a primary parameter for dividing developmental stages. Then a Logistic model of volume growth was established according to the data of pyriform fruit, and the other three fruits were employed to the suitability of this mathematical model. The resulted showed that the growth curve of augmelon appeared typical double sigmoid shape for all four shapes fruits. Based on four inflection points of volume growth curve, the fruit development of augmelon was classified five developmental stages in the order: fast stretch (FS) stage lasting for 48 days, shape stabilization (SS) stage lasting for 30 days, tardy expansion (TE) stage lasting for 51 days, suspended expansion (SE) stage lasting for 21 days and fast expansion (FE) stage lasting for 30 days. Comprehensively, volume was an ideal growth parameter for dividing fruit developmental stage of augmelon, and five-stage growth model could be applied as reference for both gardener and scientist to refer to the fruit growth status. - COLLAPSE

    The Hydrangea ‘Moonlight’ cultivar was registered in 2020 by Chonnam National University. In 2015, mophead-type H. macrophylla ‘Adria’ and mophead-type H. macrophylla ‘Ocean’ were crossed, and the progenies were grown in 2016. We screened and selected for disease resistance lines during a field trial in 2016, and investigated the flower type, floral color, and growth type from 2017-2018. Finally, we selected the distinctive line D15009. The showy sterile flower’s (sepal) color was pinkish (RHS Color Chart Purple Group 75C) and the floral head type was mophead. The inflorescence width and height were 7.80 and 14.84 cm, respectively. The average number of showy sterile flowers (calyces) per inflorescence was 152.3, and they were scentless. The average plant height was 56.83 cm and the growth type was semi-erect with stems that were bowing. Leaf length and width were 11.22 and 7.20 cm, respectively. ‘Moonlight’ was a late flowering garden cultivar. Flowers began to bloom in mid-April in the greenhouse, but in early June in the outer fields. There was a wide variation in flower color, ranging from pink, dark purple, and blue in accordance with the measurement of soil pH during gardening and pot cultivation. A new Hydrangea cultivar, ‘Moonlight’ was registered with the Korea Seed and Variety Service (plant variety protection number: 8059). - COLLAPSE

    A new strawberry (Fragaria×ananassa Duch.) cultivar ‘Highberry’ was developed by Strawberry Research Institute of Chungcheongnam-do Agricultural Research and Extension Services for forcing culture in 2018. In order to breed a new cultivar that is favorable to export with high fruit firmness and maintain the fruit quality during warm temperatures in the spring season, ‘Highberry’ originated from a cross between an unreleased selection ‘NS071608’ (female parent) with high firmness and ‘Daewang’ (male parent) with good taste and fragrance in 2013. In 2014-2017, it was originally named ‘Nonsan No. 12’ by conducting seedling selection, growth characteristics and production trials in forcing culture, and it was renamed ‘Highberry’ in 2018. ‘Highberry’ shows an erect plant type and vigorous growth habit. The leaves are dark green and thick and the leaf shape is elliptic. Fruits are conical type; fruit color is red. The first cluster of ‘Highberry’ has 13 flowers, and it is a large fruit size cultivar with an average fruit weight of 16 g. The marketable yield of ‘Highberry’ was 2,623 kg·10a-1, which is 97% of that of ‘Sulhyang’. The flower stem length of ‘Highberry’ was 37 cm long and is divided into two stems from the bottom. Fruit firmness of ‘Highberry’ was 15.3 g·mm-2, which was 3.6 g·mm-2 higher than 11.7 g·mm-2 of ‘Sulhyang’ and can be harvested until late spring. The soluble solids content of ‘Highberry’ was 10.1°Brix, which was 0.6°Brix higher than that of ‘Sulhyang’. ‘Highberry’ is resistant to Fusarium wilt but susceptible to powdery mildew and two-spotted spider mites.


    ‘하이베리’ 품종은 충남농업기술원 딸기연구소에서 2018년도에 육성한 촉성재배용 신품종이다. 경도가 높아 과실 수출에 용이하고, 봄철 고온기에도 품질이 유지되는 품종을 육성하기 위해 경도가 높은 ‘NS071608’ 계통을 모본으로 하고 맛과 향이 좋은 ‘대왕’을 부본으로 하여 2013년에 인공교배를 실시하였다. 2014∼2017년 실생선발, 특성검정, 생산력검정을 거쳐 ‘논산 12호’로 계통명을 부여하고, 2018년에 ‘하이베리’로 명명하였다. ‘하이베리’ 품종은 초형이 직립형이고 초세가 왕성하다. 잎은 진한 녹색이며, 엽육 두께가 두껍고 엽형은 타원형이다. 과실의 과형은 원추형이고 과색은 선홍색을 띤다. 정화방의 화수는 13개이고 평균 과중이 16 g으로 대과형 품종이다. ‘하이베리’의 상품수량은 2,623 kg·10a-1으로 ‘설향’의 97% 수준이다. 화경장이 37 cm로 길며 화방이 기부에서 갈라지는 형태를 나타낸다. 과실 경도는 15.3 g·mm-2으로 ‘설향’의 11.7 g·mm-2보다 3.6 g·mm-2 더 단단하고 봄철 늦게까지 수확이 가능하다. 당도는 10.1°Brix으로 ‘설향’의 9.5°Brix보다 0.6°Brix 높다. 병해충 저항성은 시들음병에 강하나 흰가루병과 점박이응애에 약한 편이다.
