Abstract

This experiment was conducted to investigate the effects of growth retardant uniconazole on the growth and flowering of Cymbidium Pine Clash 'Moon Venus' and Cym. Green Sour 'A One'. Reduction in leaf length of both cultivars was proportional to the amount (0-5g) of uniconazole and growth reduction of 'A One' was more remarkable than 'Moon Venus'. The inflorescence length was reduced 18.4% in 'Moon Venus' and 15.3% in 'A One' by 5g treatment of uniconazole. There was no significant difference in flowering time, number of inflorescences and florets and size of lower sepal regardless of uniconazole treatment. It was concluded that uniconazole treatment is effective in reducing the leaf growth of Cymbidium. However, as high concentration (5g) of uniconazole reduced the growth of inflorescence causing low quality, 1g was recommended as useful concentration.

본 연구는 왜화제 uniconazole처리가 심비디움 Pine Clash 'Moon Venus'와 Green Sour 'A One' 의 생장 및 개화에 미치는 영향에 대해서 조사하였다. 두 품종 모두 uniconazole의 처리량이 많아질수록 왜화효과가 강하게 나타났으며 'Moon Venus'보다 'A One'의 생장억제가 현저하였다. 화서장은 uniconazole 5g 처리에 의해서 'Moon Venus'의 경우 18.4%, 'A One'의 경우 15.3% 억제되었다. 개화시기, 화서수, 소화수, 하악편의 크기 등은 uniconazole 처리에 의해서 약간의 변화는 있었지만 무처리와 큰 차이는 없었다. 이상의 결과로부터 uniconazole 처리는 심비디움의 영양생장기관인 잎의 생장을 억제하는데 효과적인 왜화제이나 고농도(5g) 처리에서는 화서의 생장까지 억제하여 품질의 하락을 초래할 수도 있기 때문에 적정 처리량은 1g 정도로 판단되었다.
