糜子种子生理休眠特性的研究

Study on physiological dormancy characteristics of millet

种子在成熟收获后会有一定时间的后熟过程,即生理休眠过程。不同作物的种子后熟时间不同,它与种子的外在环境和自身条件都有关系。实验通过在同一时间采收不同生长状态的糜子种子,并在相同的时间段内进行发芽实验,结果表明:采收时间越接近成熟时间的种子休眠时间越短;在同一穗上,越靠近穗顶端的种子后熟时间越短。实验初步探索了种子熟后休眠的一般规律,以期为生产提供帮助和借鉴。

Physiological dormancy process is that seed mature in the harvest will have a certain time after the ripening process. The time of seed ripening of different crops was different, which has a relationship with the external environment and their own conditions.The seeds of different growth status in the same time was harvested, and the germination test was carried out in the same time.The results showed that the c]oser it get to the mature harvest time, the shorter the time of seed dormancy ;in the same ear, moving closer to the top of the ear the shorter the time of seeds after-ripening. Preliminary experiment explored the general regulation of seed dormancy after-ripening in order to provide help and reference for production.
