通常,落叶果树的种子采收后,要有一定的时间才能后熟、发芽;用来嫁接苹果、梨的山定子、杜梨等砧木种子,在春播前也要用湿砂层积一至二个月的时间,促使完成后熟过程,这个过程的时间能不能缩短?是生产上迫切需要解决一个问题。我们根据乙烯利具有促进植物成熟的作用,做了用乙烯利处理山定子、杜梨等种子的试验。试验中为了寻求乙烯利的适宜的配置浓度、浸种时间和相应的层积时间,采用了正交试验法,初步看出它对促进种子后熟、缩短层积时间有明显作用,小结如下:
Usually, deciduous fruit trees after harvest, there must be some time to ripening, germination; used to graft apples, pears Hill statues, pear and other rootstock seedlings, before spring sowing should also be used to layer one to two wet sand Months, prompting the completion of cooked process, the process of time can not be shortened? It is an urgent need to solve a problem in production. According to ethephon has the role of promoting plant maturity, we have done with ethephon Hill stator, pear and other seeds of the test. In order to find the suitable concentration of ethephon, the soaking time and the corresponding lamination time, orthogonal test was used in the experiment. It was initially found that it has a significant effect on promoting seed ripening and shortening the lamination time. The summary is as follows:
