不同基因型玉米种子籽粒大小与生长关系的研究

本文将四个玉米自交系按照籽粒大小分成8组作为实验材料,探讨了籽粒大小对玉米生长发育及其产量的影响,以便为优良的玉米种子繁育及生产提供参考。研究结果表明,同一自交系的籽粒大小对玉米的生育进程无相关性,对玉米前期生长有一定的影响,对玉米籽粒产量的影响则因自交系而异。

Study on the Kernel Size and Growth Relation in Various Genotypes of Maize

Four maize inbred lines were divided into eight groups according to grain size as experimental materials, and the effects of grain size on maize growth and yield were discussed in order to provide reference for good maize seed breeding and production. The results showed that the grain size of the same inbred line had no correlation with the growth process of maize, had some influence on the early growth of maize, and had different effects on the grain yield of maize.
