Abstract
|
|
|
|
The roses were cultivated in different planting densities and by the different arching methods to evaluat cut flower yield and quality. Basal shoots were more plentifully sprouted in high-arching and in low-arching than in non-arching. The days for flowering were 48 days in non-arching but 53 days in low-arching. The yield of cut flower was about 228∼230 flowers per 3.3 ㎡ in high-arching and in non-arching, while that of cut flower was reduced by 21 % in low-arching. On the other hand, the yield of high grade flower of which stem length was more than 60 ㎝ was about 62 flowers per 3.3 ㎡ in non-arching, while that was greatly increased by 121∼123% in low-arching and high-arching. Ratio of high grade flower, stem length and weight of cut flower were also high in high-arching and low-arching compared to non-arching. In the yields of cut flowers by the planting densities, the yield was higher in the 20 plants per 3.3 ㎡ and the 26 plants per 3.3 ㎡ than in the 14 plants per 3.3 ㎡.
