迄今为止,种子发芽试验都是采用培养皿法。但是,培养皿法一般只适用于测定种子生活力,不适用于测定种子活力。1983年,中国科学院植物研究所北京植物园徐本美、顾增辉同志介绍了玻板直立发芽法,为应用发芽法研究种子活力提供了较好的手段。我们在试用过程中,发现它也有不足之处:其一、不便于定期测定种子在发芽过程中的胚根、胚茎生长情况;其二,由于种子上下都覆有滤纸,透气性
To date, seed germination experiments are conducted using a dish method. However, the petri dish method is generally only applicable to the determination of seed viability, not suitable for determination of seed vigor. In 1983, Xu Benmei and Gu Zenghui of Beijing Botanical Garden, Institute of Botany, Chinese Academy of Sciences introduced the method of vertical glass-plate germination, which provided a better method for the study of seed vigor by germination method. We found in the trial process it also has shortcomings: First, it is not convenient to regularly measure the seed germination process in the radicle, the growth of stems and stems; Second, the seeds are covered with filter paper, breathable
