摘  要:
研究结果表明,抗黄1号虽在各生育阶段的叶面积系数(LAI)均比泉花10号低,但仍具有较高的LAI;在苗期、结荚期,抗黄1号的净同化率分别比泉花10号高10.6%、21.8%;抗黄1号除在开花下针期干物质积累率比泉花10号略低外,其余各个时期的积累率均大于泉花10号;产量形成期的经济系数抗黄1号也比泉花10号高;抗黄1号不仅库大、源大,而且库/源比率高,库、源的协调性也比泉花10号好。

摘  要:
The research indicated that the leaf area index(LAI) of Kanghuang 1 was lower than that of Quanhua 10 at different growth phases,but still had high LAI;the net assimilation rate(NAR) of Kanghuang 1 was separately 10.6% and 21.8% higher than Quanhua 10 at seedling stage and bearing pod stage;the dry matter accumulation rate of Kanghuang 1 was slightly higher than that of Quanhua 10 except at pegging stage;The economic coefficient of Kanghuang 1 was higher as compared to Quanhua 10 in grain-filling period.Kanghuang 1 showed not only big sink and big source,but also concerted sink-source structure.
