水稻种子活力的研究
STUDY ON SEED VIGOUR OF RICE
-
摘要: 通过本试验,我们得到如下初步结果:用种子活力表示水稻种子质量比用发芽率表示来得准确;逆境会降低种子活力,水稻种子活力的下降先于发芽率的下降,且种子活力水平与其发芽趋势之间没有必然相关性;活力指数下降的百分数可以作为衡量水稻抗逆性强弱的较好指标;幼苗生长势用根芽千重来表示较为合理。Abstract: The seed vigour of rice was studied. It has got the results as follows. Useing the seed vigour as a target of seeds quality was better than useing the germination percentage. The seed vigour of rice was decreased in adversity. The decrease of seed vigour was earlier than that of germination percentage. And there was no relation between the level of seed vigour and that of germinating viability. Decreasing percentage of the index of seed vigour can be used as a good target in measuring the level of stress resistance of rice. It was good to use dry weight of both roots and buds to express the growth vigour of rice seedlings.
