- To assess the feasibility of using plant-factory-produced seedlings for vegetable production, this study compared the seedling quality and early growth of tomato seedlings grown in a nursery greenhouse (GH seedlings), serving as the control group; a plant factory and then a nursery (PG seedlings); and a plant factory (PF seedlings). Seedlings from all treatments were then transplanted in a greenhouse and all were grown together. The average daily temperatures in the plant factory and nursery greenhouse were similar, but the difference between day and night was more pronounced in the nursery greenhouse. The average daily relative humidity was higher in the plant factory. The relative growth rate was highest for the PF seedlings, but the compactness and the Dickson quality index were highest in the PG seedlings. Regarding the belowground characteristics, the number of roots was greatest in the PF seedlings, but the root surface area, average root length, and quantity of fine roots were best in the PG seedlings. In terms of chlorophyll fluorescence, the Fv/Fm ratio showed normal values ranging from 0.78 to 0.84 across all treatments. However, the Pi_Abs, ABS/RC, TRo/RC, and ETO/RC parameters indicated that the PF seedlings experienced more compared to the seedlings from the other treatments. Plant heights were significantly different among the treatments immediately after transplanting, but by week 6, differences among the treatments became insignificant for most indices. Though not treated with growth regulators, the PG seedlings exhibited robust seedling quality without overgrowth, good root establishment, and good growth trends similar to those of the GH seedlings after transplanting. Therefore, this study determined that seedlings cultivated up to the temporary planting stage in a PFAL and then cultivated in a greenhouse until transplanting exhibit excellent seedling quality, root establishment, and growth after transplanting, making them suitable for commercial seedling production. - COLLAPSE

- This study investigated the effects of several fruit size factors on quality changes and the incidence of internal physiological disorders during the simulated export and distribution of ‘Wonhwang’ pears (Pyrus pyrifolia Nakai), the main early-season variety of Korean pear for export. Experiments were conducted on fruits packed (5 kg base) in four different grades of export standards at the Cheonan Pear Export Sorting Facility in 2023. All packaged fruits were stored at 1°C for 30 days to simulate export transportation, followed by a simulated shelf life at 25°C for 21 days. The soluble solids content did not vary by size, but the titratable acidity was lowest in the smallest fruit (Size 10) over the entire shelf lifetime. In addition, Size 10 fruits showed a higher respiration rate and greater ethylene production than fruits of other sizes. It was also found that the largest fruit (Size 7) and smallest fruit (Size 10) had lower levels of ethanol-insoluble substances than the medium-grade fruits of Sizes 8 and 9. The incidences of physiological disorders for fruits designated as Sizes 8 and 9 were lower in with regard to core browning and flesh browning compared to the largest fruit (Size 7) and smallest fruit (Size 10). Fruits of Size 8 and size 9 were judged to be the most suitable export standards for ‘Wonhwang’ pears. - COLLAPSE

- Visible and near-infrared (Vis/NIR) spectroscopy is widely used to assess plant physiological characteristics in various horticultural crops. As cut flower longevity has become important for marketing, a rapid technique for estimating the internal quality of these products is necessary. In this study, we estimated the primary physiological factors affecting the water content and soluble solids content (SSC) using Vis/NIR spectroscopy to predict the postharvest quality and vase life of cut roses. First, cut roses were subjected to either air exposure (AE) or a sucrose treatment (ST) to identify the reflectance wavelengths correlated with water and sucrose in these plants. The AE flowers exhibited a rapid decrease in the water content and fresh weight, with their vase life consequently shortened compared to that of the control flowers. Vis/NIR results revealed a large spectral separation at a wavelength of approximately 550 nm, and a linear regression analysis indicated a high positive correlation between 550 nm and the water content in the petals. The ST treatment increased the SSC, fresh weight, and vase life of cut flowers. A distinct separation in the spectral reflectance was observed at a wavelength of 600 nm. The SSC level was significantly related to the reflectance at 600 nm; however, the result suggested that the internal sucrose level in rose petals could not be explained sufficiently by the reflectance at 600 nm. Thereafter, cut roses underwent export simulation under either dry (DT) or wet conditions (WT) for three days. The WT flowers maintained a higher fresh weight and water content during the transport and vase life periods and consequently had a longer vase life (5.5 d) than the DT flowers (4.2 d). Linear regression analyses revealed a relatively high coefficient of determination between the 550 nm wavelength and water content (r2 = 0.77) and vase life (r2 = 0.68). Our results indicate that it is possible to evaluate the major quality attributes of cut flowers based on Vis/NIR data. Based on these results, we can conclude that Vis/NIR spectroscopy is a reliable and practical method for estimating the postharvest quality and longevity of cut flowers. - COLLAPSE

- We aimed to determine the appropriate amount of organic fertilizer and to provide locally adaptable standard-fertilization rates for young Eucalyptus gunnii plantations in South Korea on May 10, 2022. Four fertilizer treatments were applied annually: 0, 25, and 50 g of actual T-N per tree for 0%, 100%, and 200% oil cake, respectively; and 25 g T-N as a chemical fertilizer treatment. The chemical fertilizer treatment reduced the soil pH to 5.87, presumably owing to high nitrification of NH4+ and high loss of NO3- observed for low NO3- concentrations under chemical fertilization. Both the 200% oil-cake and chemical fertilizer treatments increasd the soil organic matter content and P2O5 and K2O concentrations while reducing the CaO and MgO concentrations. A high soil organic matter content caused 2.47%, 2.49%, 2.33%, and 2.06% increases in foliar T-N concentrations in the 200% oil-cake-treated plots, the 100% oil-cake-treated plots, the chemical fertilizer treatment, and the 0% oil-cake-treated plots, respectively. The lowest foliar K concentrations were observed in the 0% oil-cake-treated soils concomitant with highest foliar Ca and Mg concentrations. Tree height and trunk thickness were lowest for the 0% oil-cake-treated plots from 30 to 450 days after transplant (DAT). Tree trunks were significantly increased in thickness by the 200% in oil-cake-treatment from 150 to 450 DAT, concomitant with increased numbers of shoots and leaves. As the trees grew higher, the leaf chlorophyll content decreased from 330 to 390 DAT across treatments, particularly under the 0% oil-cake treatment. The 200% oil-cake treatment significantly increased the root, shoot, leaf, and whole tree dry mass in the following order: 100% oil cake > chemical fertilizer > 0% oil cake trees. High (> 53%) tree-survival rates were observed under the chemical fertilizer at both 510 and 690 DAT, while the lowest survival rates (27%) were observed for the 0% oil-cake treatment. Tree survival was correlated positively with the foliar T-N, K, trunk thickness, tree height, number of shoots, the total leaf dry weight, and the average leaf dry weight. The highest amount (450 mL) of hydrosol was extracted from the leaves of the 200% oil-cake-treated trees. Cut foliage can last up to seven days in water regardless of fertilization. The 200% oil-cake treatment was the recommended organic fertilizer rate for improving nutrient cycling and promoting early tree growth in Eucalyptus gunnii plantations. - COLLAPSE

- This study was conducted to evaluate the effects of biodegradable (BD) films mulched in crop rotation fields, specifically pepper from April to September and onion from October to May, as well as the effects of the film residue on soil mineral nutrition and crop growth outcomes in South Korea. Five treatments were used: non-mulching (NM), polyethylene (PE) film mulch, and three BD film mulches (referred to as F, H, and E). Film F was made using polybutylene adipate-co-terephthalate (PBAT) and polylactic acid (PLA); film H was made using PBAT+PLA; and film E was made using PLA+starch. The pepper field showed greater levels of degradation of all BD films, in particular for the H and F films, compared to the films in the onion field under exposure to excessively warm temperatures and high rainfall amounts during the cultivation period. The F film-mulched pepper plots had the lowest soil moisture level of ‒47.0 kpa on August 1, 2023 owing to high biodegradability, and the values for the onion plots remarkably in April of 2024. Seasonal soil electrical conductivity decreased in both the pepper and onion plots, with significantly higher levels in the mulch plots than in the NM plots in the pepper field at 0 and 30 days after transplanting (DAT). In most cases, no significant differences were observed in the soil mineral nutrient levels between the treated pepper and onion plots. The stem height increased in peppers grown under PE film mulching at 60 DAT and under F film mulching at 120 DAT. The number of pepper leaves increased with the BD mulching treatments at 60 and 90 DAT, with higher SPAD readings observed at 60 DAT. The greatest stem diameter and leaf fresh weight values were observed at 180 DAT in the E film-mulched onions. All mulch treatments increased the number of pepper fruits. The H film mulching treatment produced a large number of bulbs and resulted in the highest yield of 61.1 ton ha-1, followed by mulching with the E (59.4 ton), PE (48.5 ton), F (43.3 ton), and NM (34.0 ton) films. Breakdown of BD films, particularly the F film, occurred on topsoil with considerable disintegration at a depth of 10 cm in the onion field after the completion of one crop rotation cycle. Adverse effects from the remaining BD residue were not observed for the subsequent period of onion growth, and the H and E films were recommended to preserve soil health and improve crop productivity of warm- and cool-season vegetables. - COLLAPSE

- This study investigated physiological and biochemical changes during the cutting propagation process in different tea plant varieties and the effects of these changes on the rooting efficiency. Dynamic changes in soluble sugars, soluble proteins, polyphenol oxidase (PPO), peroxidase (POD), indole-3-acetic acid oxidase (IAAO), endogenous hormones (indole-3-acetic acid (IAA), cytokinins (CTK), and abscisic acid (ABA)) were monitored and analyzed during the cutting propagation process of six tea plant varieties: ‘Hainan Dayezhong’ (HD), ‘Yunnan Dayezhong’ (YD), ‘Fuan Dabai’ (FA), ‘Fuding Dabai’ (FD), ‘Jinxuan’ (JX), and ‘Huang Guanyin’ (HG), which have varying rooting abilities. The study revealed significant differences among the varieties in terms of the rooting time and rooting ability. JX demonstrated the highest rooting rate and fastest rooting process, with 86.3% of cuttings rooting successfully, while HD exhibited the lowest rooting rate, with only 22.86% of cuttings rooting successfully. Varieties with high rooting rates showed higher soluble sugar contents at the initial rooting stage, a significant early increase in PPO and POD activities followed by a decline, and reduced IAAO activity levels during the induction and development stages of adventitious root (AR) formation. Higher IAA/CTK and IAA/ABA ratios were generally associated with increased rooting rates. Medium-leaved varieties exhibited higher root formation rates overall, especially JX and FD. Our study shows that during the critical period of AR formation, several key physiological and biochemical changes determine differences in rooting ability among tea plant varieties. An increase in the IAA content was crucial for inducing root primordia in varieties with high rooting rates. Additionally, a decrease in the IAAO activity, elevated POD and PPO activities, and the rapid accumulation of soluble sugars and proteins were closely related to successful rooting. In contrast, low-rooting varieties exhibited less pronounced changes in these parameters, potentially explaining their lower rooting efficiency. - COLLAPSE

- This study aimed to improve the stem-cutting propagation efficiency and morphophysiological characteristics of the variegated ornamental foliage plant Hedera algeriensis cv. Gloire de Marengo using two types of auxins and four concentrations for each type of auxinic rooting promoter tested here. The following nine concentrations were used: control; 3-indolebutyric acid (IBA) at 250, 500, 750, and 1000 mg·L-1; and 1-naphthylacetic acid (NAA) at 250, 500, 750, and 1000 mg·L-1. Plant size parameters varied with the auxinic rooting promoter concentrations, with IBA and NAA producing larger plants relative to the control. Shoot dry weight was highest at both IBA 500 mg·L-1 and NAA 500 mg·L-1, whereas root dry weight was significantly higher across all treatments compared to the control. Total dry weight followed patterns similar to the shoot dry weight. The moisture content showed no significant differences among the treatments. The Dickson quality index (DQI) was higher in all treatments except for the control, indicating improved plant quality with auxinic rooting promoters. The normalized difference vegetation index (NDVI) and maximum quantum yield (Fv/Fm) were highest at IBA 500 mg·L-1 and NAA 500 and 750 mg·L-1, indicating superior physiological responses in these treatments. The modified chlorophyll absorption ratio index (MCARI) was highest in the control treatment, while the photosynthetic performance index (PIABS) was highest in the NAA 500 mg·L-1 treatment, suggesting a lower chlorophyll content in the control and enhanced photosynthetic apparatus integrity due to the NAA 500 mg·L-1 treatment, respectively. In conclusion, NAA 500 mg·L-1 was the most effective concentration for ‘Gloire de Marengo’ stem-cutting propagation, followed by IBA 500 mg·L-1. These findings provide valuable insights into optimizing auxinic rooting promoter concentrations, offering crucial guidance for improving propagation efficiency and morphophysiological characteristics of this cultivar. - COLLAPSE

- The peel colors of ‘Hongro’ and ‘Greenball’, apple cultivars bred and cultivated in Korea, were deep red and greenish yellow, respectively, at the time of harvest. ‘Hongro’ had more peel redness than ‘Greenball’, while ‘Greenball’ had more peel yellowness (b value) than ‘Hongro’. As a result of separating proteins extracted from the peels of the two apple cultivars by means of two-dimensional electrophoresis (2-DE), 17 protein spots in ‘Hongro’ and 12 in ‘Greenball’ exhibited expression rates more than twice those in the other cultivar. Through a matrix-assisted laser desorption/ionization time-of-flight/time-of-flight mass (MALDI-TOF/TOF) analysis, ten spots in ‘Hongro’ and five spots in ‘Greenball’ were identified as proteins with specific physiological functions. In’ Hongro’, the following proteins were expressed at higher levels than in ‘Greenball’: NADP-dependent malic enzyme (spot 1), enolase-like (spot 2), formate dehydrogenase, mitochondrial (spots 3 and 9) and glyoxalase Ⅰ (spot 13) involved in carbohydrate metabolism; 12-oxophytodienoate reductase 2-like (spot 6) catalyzing the biosynthesis of JA, a type of plant hormone; β-(cyanoalanine synthase) CAS 1 (spot 8) involved in amino acid metabolism; L-ascorbate peroxidase (AP) 2, cytosolic (spot 17) and glutathione S-transferase (GST)-like (spot 19), a type of antioxidant enzyme; and agglutinin alpha chain-like (spot 21), an allergen. In ‘Greenball’, the following proteins were expressed at higher levels than in ‘Hongro’: DJ-1 homolog D-like (spot 4) and thiamine thiazole synthase, chloroplastic (spot 11), which are involved in carbohydrate metabolism; ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO) activase, chloroplastic-like (spot 5), oxygen-evolving enhancer protein 1, chloroplastic (spot 16), and PsbP domain (PPD)-containing protein (spot 18), all of which are involved in photosynthesis. Meanwhile, among the proteins whose expression rates differed between ‘Hongro and ‘Greenball’, no proteins directly related to the development of peel color were identified. Additionally, seven proteins in ‘Hongro’ and seven in ‘Greenball’ were identified as unidentified or uncharacterized proteins. These results can be used for a wide range of studies related to the sensory quality, characteristics, production, and preservation of apples and can also serve as basic data for improving target traits in the breeding of new varieties. - COLLAPSE

- In the agricultural sector, crop classification serves as a crucial indicator for evaluating the adaptability of crops influenced according to factors such as climate, soil conditions, and altitude. In this context, this study aims to analyze the accuracy of crop classification models based on spectral index extraction methods using multi-spectral satellite imagery for apple and pear crops. For this purpose, multi-spectral images were acquired for Nonsan city in Chungcheongnam-do, and apple and pear crops were classified according to the main spectral index extraction methods. The results showed that a machine learning algorithm, support vector machine (SVM), yielded higher accuracy when using the top 50% of the spectral indices (R2 = 0.7487) compared to the use of all spectral indices. Additionally, a deep learning model, multi-layer perceptron (MLP), showed relatively little variation in accuracy based on the spectral index extraction method (R2 = 0.8902). Therefore, the findings of this study present an efficient and scientific spectral index extraction method for classifying various crops, including apples and pears, across a wide range.

- Phenolic compounds are well known to be among the major bioactive compounds found in various plant sources. It has been reported that Sambucus sieboldiana, found on Ulleung Island in Korea, contains phenolic compounds, suggesting potential health benefits. Thus, in this study, we determined the inflammatory activity of Sambucus sieboldiana with Raw 264.7 mouse macrophage cells. Phenolic compounds isolated from Sambucus sieboldiana were exposed to LPS-stimulated macrophages to determine whether an anti-inflammatory effect existed. The inflammation-associated protein expression, activity, and gene expression levels were measured by means of ELISA, a western blot analysis, and qPCR. Phenolic compounds from Sambucus sieboldiana inhibited the expression of iNOS, COX-2, and their downstream products PGE2 and NO, which are part of the NF-kB signaling pathway. The mRNA gene expression levels of pro-inflammatory cytokines, in this case TNFα, IL1β, IL6, MCP1, and PTGES2, were significantly decreased. These results showed that phenolic compounds from Sambucus sieboldiana have an anti-inflammatory effect, suggesting that Sambucus sieboldiana can potentially be used as an anti-inflammatory treatment, such as therapeutic and/or cosmetic products for the skin, particularly for skin inflammation. However, further in vivo studies using phenolics from Sambucus sieboldiana are needed to support the current findings.
