播种前处理种子的方法相当多,可以分为物理的、化学的和生理学的。各方法的效果首先决定于种子休眠类型(见表1),种子的外表特征也有较大的影响,并且要认真保持处理所必要的条件。下面简略叙述这些方法,解除复被物阻碍作用的各种措施均属于物理方法:有全部切除复被物、划痕、碰撞、各种机械处理以及淘洗等方法。化学作用包括用碱水、酸液处理种子或果实,以及用某些其它物质促进复被物透性的增加、生理方面的主要作用是影响胚本身的
There are quite a few ways to treat the seeds before planting, which can be divided into physical, chemical and physiological. The effectiveness of each method depends primarily on the type of seed dormancy (see Table 1), the appearance of the seeds also has a greater impact, and careful maintenance of the necessary conditions. The following is a brief description of these methods. The various measures to relieve the effect of the complex object are all physical methods. There are all methods of removing the complex object, scratches, collisions, mechanical processing, and panning. Chemical effects include the treatment of seeds or fruits with alkaline water, acids, and the use of certain other substances to promote the increase of the permeability of the coating, the major physiological effect being on the embryo itself
