在马铃薯栽培上,化学刺激剂常常用来打破新收块茎的休眠期,在长期貯藏时阻止其发芽,以及防止落花等。可是,利用化学刺激剂来提高植物的生产力的问题,尽管过去也曾进行过研究,还是研讨得不够的。而且大家知道,块茎发芽时,顶端芽眼的主芽开始生长较早。而侧芽、尤其是脐部芽眼,开始生长较慢,而且常常不发芽。这样就减少了茎枝的形成,并影响到马铃薯的产量。据许多作者的资料,块茎幼芽发芽的生理活性与其中存在的生长素有关,随着其含量的提高而增强。
In potato cultivation, chemical stimulants are often used to break the dormancy of newly harvested tubers, prevent them from sprouting during long-term storage, and prevent falling flowers. However, the use of chemical stimulants to increase the productivity of plants has not been explored in spite of previous studies. And we all know that when the tubers germinate, the buds of the top buds begin to grow earlier. The lateral buds, especially the umbilicus buds, begin to grow slower and often do not germinate. This reduces stem formation and affects potato yield. According to many authors’ information, the physiological activity of tuber germination relates to the auxin present in it, and increases as its content increases.
