三、种子生理1、发芽生理种子发芽所需要的条件有温度、水分、氧气和水。在这些条件适宜的时候,休眠中的胚就开始生长,也就是说开始发芽。进行发芽试验之前,学习和掌握关于这些条件的基本知识是很有必要的。再者,在实际从事发芽试验的时候,还必须掌握除此而外的休眠、硬壳种子等生理现象方面的知识。(1)温度 Third, the seed physiology 1, germination physiological seed germination conditions required temperature, moisture, oxygen and water. When these conditions are right, dormant embryos begin to grow, which means that germination begins. Before conducting a germination test, it is necessary to learn and master the basics of these conditions. Furthermore, knowledge of physiological phenomena such as dormancy, crustacean seeds, and the like must also be mastered in actual germination tests. (1) temperature
