摘要
对3个近年来在黑龙江省推广面积比较大和有代表性的品种(系)的干物质积累与产量的关系研究结果表明,在标准施肥水平条件下,籽粒产量与生物产量,特别是收获指数呈正相关。最大LAI与生物产量及经济产量均呈正相关,LAI大,籽粒产量高,但LAI过大,产量有降低的趋势。鼓粒期干物重与籽粒产量呈显著正相关。最大CGR与产量显著正相关。NAR和RGR均与籽粒产量呈正相关,但二者和籽粒产量的相关性大小基因型之间存在差异。
Three soybean varieties were tested in the experiment station of Northeast Agricultural University. The results showed that yield was significantly correlated with biomass and harvest index, especially the latter. LAI of soybean was significantly correlated with yield, but yield began to decline when LAI was too high. Dry matter weight of fulling period was correlated with yield. Maxim CGR was significantly correlated with yield. NAR and RGR were correlated with yield.$$$$
