通常,辨别种子有无生活力是通过发芽试验测定其发芽率而定。这种方法需时较长,不能满足应急需要,尤其对深休眠状态的种子,根本无法正确判断其生活力。因此,有必要寻找一种快速测定种子生活力的方法。 1985年,我们在本校进行了7—8次试验,证明红墨水染色法是快速、准确地测定稻、麦、玉米种子生活力的简便方法。其原理是:一切活细胞的原生质膜对物质的吸收都具有选择性,即对一些物质可以吸收,对另一些物质则拒绝吸收。而死细胞的原生质
In general, identifying the viability of a seed is determined by measuring its germination rate by germination tests. This method takes a long time, can not meet the emergency needs, especially for the seeds of deep dormancy, simply can not correctly judge its viability. Therefore, it is necessary to find a rapid determination of seed viability method. In 1985, we carried out 7-8 experiments in our school to prove that the red ink dyeing method is a quick and accurate method for measuring the viability of rice, wheat and corn seeds quickly and accurately. The principle is that all living cells of the plasma membrane of the substance of the absorption of the selective, that is, some substances can be absorbed, while others refuse to absorb. And dead cell protoplasm
