用暗室短光照处理和分期播种的方法研究了黄麻两个栽培种中不同熟型品种的光温反应特性,对感光性实质和生育期长短的形成进行了分析。结果表明:两个种间在感光株龄和完成光诱导时间上存在差异且圆果种临界光长表现出熟型间的不同;光期诱导过程的中断与否对光照阶段的通过影响不大,生育进程大体相同;在一定播期范围内,发育转变仅决定于光照条件,温度效应不甚明显。 The light-temperature response characteristics of different ripe varieties in two cultivars of jute were studied by the darkroom short-sowing treatment and the staged sowing method. The formation of the light-sensitive substance and the growth period was analyzed. The results showed that there was a difference in the light-induced plant age and light-induced time between the two species, and the critical light length of the round fruit species showed a difference between ripened varieties. The interruption of the light-induced process had little effect on the passage of light , The same fertility process; within a certain sowing date, the developmental change is only determined by light conditions, the temperature effect is not obvious.
