不同上山时期处理对蝴蝶兰花芽分化与发育的影响

Flower Bud Differentiation and Development of Phalaenopsis on Different Treat Time at High Elevation

研究了不同上山时期处理对蝴蝶兰不同品种花芽分化和发育的影响以及高山处理下蝴蝶兰花梗的发育规律.不同品种在高山催花处理下至花芽分化所需的时期不同,对昼夜温差的反应也不同.蝴蝶兰的花梗在上山处理30～80d内迅速伸长,上山处理40～63d左右花梗长度可达10cm,但品种和不同上山时期处理间存在一定的差异.

The flower bud differentiation and development of 4 varieties of Phataenopsis had been studied on different treat time at an elevation of 700 meters. The period from treat day to flower bud differentiation is 30 to 80 changed by different varieties. The length of florescences of 4 varieties elongated very rapidly in days after treating, and reached 10cm within 40 to 63 days, there were difference between varieties and treat time. It is necessary to choice treat time according to varieties.
