Abstract

Miscanthus sinensis (Poaceae) cultivars have great values as ornamental grasses and adapt well to various environmental conditions. To assess the inflorescence visibility of seven popular Miscanthus cultivars (‘Gold Breeze’, ‘Strictus’, ‘Morning Light’, ‘Variegatus’, ‘Gracillimus’, ‘Kleine Fontäne’, and ‘Common’), the heading performance and morphological characteristics were analyzed. The test cultivars were transplanted and cultivated on research plots in 2013 and data were collected from July 2017 to February 2018. Among the six cultivars, except ‘Gold Breeze’, which had not bloomed during the research period, ‘Kleine Fontäne’ showed the longest heading period and the highest peduncle density. Heading patterns were classified in the early and the late heading patterns. The early heading pattern cultivars (‘Kleine Fontäne’, ‘Common’, and ‘Strictus’) had a high weekly heading rate (WHR), and reached later heading peak time with low mean heading rate (MHR). However, the late heading pattern cultivars (‘Variegatus’, ‘Gracillimus’, and ‘Morning Light’) had high WHR at the beginning of the heading initiation and reached earlier heading peak time with high MHR. The changes of inflorescence stage were classified into the flowering season (stage 1), the seed maturation (stage 2), and the seed shatter stages (stage 3). The inflorescence colors were expressed with a reddish (‘Strictus’, ‘Morning Light’, ‘Variegatus’, ‘Gracillimus’, and ‘Common’) and a yellow-greenish (‘Kleine Fontäne’) color in stage 1. The color difference value (ΔE*ab) was greater at stage 1 and stage 2; however, ΔE*ab was decreased in stage 3 compared with the reference inflorescence color of ‘Common’. The morphological characteristics of inflorescences were significantly different among the cultivars, such as the plant height, stem length, dissociation index, length, width, length/width ratio, raceme density, and spikelet density. On the assessment of inflorescence visibility, the morphological characteristics showed a decisive component in ‘Common’, ‘Strictus’, ‘Variegatus’, and ‘Gracillimus’; on the other hand, the heading characteristics were more influential on visibility in ‘Kleine Fontäne’ and ‘Morning Light’. These results suggest that the inflorescence visibility of Miscanthus cultivars was determined by various factors of the heading and morphological characteristics of inflorescence.

경관 가치가 우수하고 다양한 생육환경에 잘 적응하는 관상용 그래스인 억새(M. sinensis) 원예품종 7가지(‘Gold Breeze’, ‘Strictus’, ‘Morning Light’, ‘Varieagatus’, ‘Gracillimus’, ‘Kleine Fontäne’, ‘Common’)의 출수 특성과 화서의 형태적 특성을 분석하고 화서의 가시성을 평가하였다. 공시 재료는 2013년 시험포장에 정식, 재배하였고 2017년 7월부터 2018년 2월까지 데이터를 수집하였다. ‘Gold Breeze’를 제외한 6개 품종이 출수하였는데 ‘Kleine Fontäne’의 출수 기간이 가장 길었으며 화경 밀도도 가장 높았다. 출수 패턴은 조기와 만기로 구분되었으며 조기 출수 패턴의 품종(‘Kleine Fontäne’, ‘Common’, ‘Strictus’)은 출수 초기에 주간 출수율(WHR)이 높은 경향이었으나 출수 피크타임에 늦게 도달했고 출수 집중도(MHR)도 낮았다. 만기 출수 패턴의 품종(‘Varieagatus’, ‘Gracillimus’, ‘Monring Light’)은 출수와 동시에 WHR이 높았고 출수 피크타임에 일찍 도달했으며 MHR도 높았다. 화서 변화 단계를 개화기(stage 1), 종자 성숙기(stage 2), 종자 탈립기(stage 3)로 구분하였는데 화서의 색채는 stage 1에서 적색 계열(‘Strictus’, ‘Morning Light’, ‘Variegatus’, ‘Gracillimus’, ‘Common’)과 황록색 계열(‘Kleine Fontäne’)로 구분되었다. ‘Common’ (reference color)과의 화서 색 차이 값(ΔE*ab)은 stage 1과 stage 2에서 컸으며 stage 3에서는 줄었다. 화서의 형태적 특성은 초고, 간장, 분리 지수, 길이, 폭, 장폭비, raceme 밀도, spikelet 밀도에서 품종 간 유의한 차이가 있었다. 출수 특성과 형태적 특성을 바탕으로 화서 가시성 결정 특성을 품종별로 분석한 결과 ‘Common’, ‘Strictus’, ‘Variegatus’, ‘Gracillimus’는 화서의 형태적 특성이 두드러졌고 ‘Kleine Fontäne’, ‘Morning Light’는 출수 특성이 화서의 가시성 결정에 기인한 것으로 나타났다. 본 연구에서 억새 원예품종들의 화서 가시성은 평균 3.1 - 3.8을 보였으며 출수 특성과 화서의 형태적 특성의 다양한 요인에 의해 가시성이 결정되는 것으로 분석되었다.
