摘　　要：将蝴蝶兰Phalaenopsis分别用 2 2 16℃ ,2 3 18℃ ,2 5 2 0℃ ,30 2 8℃ (日 夜 )温度处理。结果表明诱导开花的最适温度为 2 5 2 0℃ ,更低温度虽然可提早开花但均引起一定数量的花败育 ;较低温处理组的花序轴直径及开花的花朵数均小于常温组。 30 2 8℃处理期间 (2 0 5d)均未抽出花序轴 ,表明高温条件下蝴蝶兰不能诱导开花。分别将 3组较低温度处理 30d和 4 0d后的蝴蝶兰移至常温中培养可以与持续温度处理组同时开花 ;2 5 2 0℃处理并已抽出不同高度花序轴的蝴蝶兰移入 30 2 8℃中 ,发现蝴蝶兰均能提早开花 ,但花器官发育受阻。Phalaenopsis plants were treated under different temperatures of 22/16 ℃,23/18 ℃,25/20 ℃ and 30/28 ℃(day/night),respectively. The results showed that 25/20 ℃ was the optimum temperature for inducing flowering. If the plants were maintained at 30/28 ℃,blossom did not occur. After treated for 30d and 40d under 22/16 ℃,23/18 ℃,25/20 ℃, they were moved to the control environment, the similar inducing effect could be achieved. However, the flower development was blocked when Phalaenopsis plants were removed at 30/28 ℃ after the spiking under 25/20 ℃.
