播种怎样的种子较好,这是农家最关心的问题之一。用遗传性优越的种子,这是不必说的;而同一品种有大粒种子和小粒种子之分,尽管其遗传性相同,亦有各式各样的见解发表。本文拟就这个问题稍加考察。为了说明的方便,把内容结合作物的生长发育,就发芽率、生存率、生长、各器官组织及产量与粒重的关系加以说明。同时,文中籽粒的轻重和大小的关系,以粒重者作为大粒,轻者作为小粒。
Seeding what kind of seed is better, this is one of the most concerns farmers. Needless to say, it is needless to say the genetically superior seeds, while the same species has the seeds of large seeds and the seeds of small seeds. Although their heredity is the same, a variety of opinions are also published. This article is intended to examine this issue a little. For convenience of illustration, the content is described in relation to the growth and development of the crop on the relationship between the germination rate, the survival rate, the growth, the respective organ tissues and the yield and grain weight. In the meantime, the relationship between the severity and the size of the grain in the text is taken as the large grain and the light grain as the small grain.
