黃麻早播出現早花现象,主要是由于日照长度較短所引起。黄麻品种新长一号对日照长度的反应很敏感,它的光照阶段开始得既早,而且通过得又快,在出苗后9天給予6—12天的10小时短日照便可引起早花。在短日照中的成长植株,經过4—5天生长錐便开始分化,14—17天現蕾。花芽分化的整个过程可以分为五級:第一級是花芽原基突起,第二級是蕓片形成期,第
Early emergence of jute early flowers appear phenomenon, mainly due to the shorter length of the sunshine caused. The jute variety Xintiao 1 is sensitive to the length of the sunshine and its light phase begins early and passes very fast, giving 10 to 10 days of short daylight at 9 days after emergence to cause early flowering. Growing plants in short sunshine began to differentiate after 4-5 days of growth cone and buds 14-17 days. The whole process of flower bud differentiation can be divided into five stages: the first stage is the primordia of flower buds, the second stage is the period of the formation of the disc,
