팔레놉시스 냉방재배시 당밀 처리가 생육과 개화에 미치는 영향을 구명코자 시험한 결과는 다음과 같다. 엽수 및 엽폭은 당밀처리에서 증가하였으나 엽장은 처 리간에 차이가 없었으며, 화경장 및 소화수는 냉방전 당밀 2% 희석액을 4회 처리시 증가하는 경향을 보였 다. 화경발생율은 처리횟수에 관계없이 당밀처리에서 증가하였고, 개화기는 웨딩 품종에서 빨랐다. 상품수량 은 웨딩 품종에서 무처리에 비해 냉방전 2%의 당밀 4회 처리에서 9.4% 증가하였다.
This study was carried out to investigate the effect of molasses(easily decomposable carbohydrate) on growth and flowering in cooling cultivation of Phalaenopsis. The results obtained are as follows; Leaf number and width were increased with molasses 2% treatment, and leaf length was no difference among treatements. Flower stalk length and number of floret showed increasing trend by 4 times treatment with molasses 2% at 50 days before cooling cultivation. Flower stalk occurrence rate was increased with molasses 2% regardless of molasses treatment frequency. Blooming was pasted with ‘WeddingPromade’ cultivar. Commercial yield was increased as 9.4% by 4 times treatment with molasses 2% at 50 days before cooling cultivation compared to control.
