暗期中断对萝卜抽薹开花的影响

Preliminary Study on the Effect of Night-break on Bolting and Flowering of Radish

萝卜经过春化后不同的暗期中断时间、处理天数的实验 ,结果表明 :春化 3 0d后黑夜中间暗期中断处理 1h ,持续 15d以上就可以引起萝卜在短日照的条件下抽薹开花。不同的品种对处理条件的要求也不同 。

When the seeds had been vernalized for 30 days, radish can flower and bolt under a short-daylight condition with one-hour night-break treatment for more than 15 days. The responses to the night-break significantly differed among the varieties because of their heredity.
