Abstract

This experiment was conducted to investigate the effects of a growth retardant uniconazole treatment time on the growth and flowering of Cymbidium Pine Clash 'Moon Venus' and Cym. Green Sour 'A One' in order to develop a substitutional technique on the highland cultivation. Leaf growth of both cultivars was more remarkably reduced by earlier uniconazole treatment time and growth reduction of 'A One' was more remarkable than 'Moon Venus'. Flowering time of 'Moon Venus' treated with uniconazole at May 7 and 27 was accelerated by 5 and 6 days respectively. Moreover, the number of inflorescences and florets showed a tendency to increase. However there was no difference in flowering time of 'A One' among treatments but there was a tendency to decrease in the number of inflorescences and florets by uniconazole treatment. In both cultivars, there was no difference among treatments in the length and width of lower sepal which represent the floret size.

본 연구는 심비디움의 고랭지 이동재배의 대체기술개발을 위하여 생장억제제 uniconazole 처리시기가 심비디움 Pine Clash 'Moon Venus'와 Green Sour 'A One'의 생장 및 개화에 미치는 영향에 대해서 조사하였다. 두 품종 모두 uniconazole의 처리시기가 빠를수록 왜화효과가 강하게 나타났으며 'Moon Venus' 보다 'A One'의 생장억제가 현저하였다. 'Moon Venus'의 경우 5월 7일과 27일 uniconazole 처리에 의해서 개화가 각각 5, 6일 촉진되었으며 또한 화서수, 소화수도 증가하는 경향을 나타내었다. 'A One'의 경우 개화시기는 처리간에 차이가 없었으나 uniconazole처리에 의해서 화서수와 소화수가 감소하는 경향을 나타내었다. 두 품종 모두 소화의 크기를 나타내는 하악편의 길이와 폭은 처리간에 차이가 없었다.
