摘要
通过盆栽的方法对黑龙江省近50个水稻品种(系)的叶片及穗部性状特征进行了比较分析。结果认为产量的形成是源库互作的结果,颖花数量是决定产量高低的关键。
The leaf and spike characteristics of nearly 50 rice varieties(lines) were analyzed by means of pot culture. The result indicated that yield formation was affected by source and sink relation and spikelets was the major determinate factor of rice yield.
