摘　　要：本文研究不同大豆品系（种）鼓粒期冠层叶片的净光合速率、转化酶活性与单株籽粒产量的关系。结果表明，不同大豆品系（种）的净光合速率、转化酶活性和籽粒产量均存在明显差异。大豆籽粒产量与叶片净光合速率之间里显著正相关（ｒ＝０．５６６８＊），而与叶片转化酶活性之间表现负相关，但不显著（ｒ＝０．１７３３）。本研究筛选出两个高光效高产大豆品系 ９７０２和 ９２０８—５，它们的净光合速率比早熟１８号高光效对照品种分别提高几２９％和１９．２％，籽粒产量分别提高３３．４９％和２６．２５％。Fifteen cultivated soybean strains (variety) bred by our Lab. were used to study relationships between net photosynthetic rate(N-PHR), invertase activity (ITaseA) of leaf in stage of seed forming and seed weight per plant(SWtP). The experimental results indicated that the differences in N-PHRs, ItaseAs and SWtps of these strains(variety) were very notable. The correlation between N-PHRs and SWtPs of these materials was positive and significant (r=0. 5668* ), but there was an non significant negative correlation (r= -0. 1733) between ITaseAs and SWtPs of these materials. Strains 9702 and 9208- 5 among these experimental materials had much higher N - PHRs(11. 29 % and 19. 2 % ) and SWtPs (33. 49 % and 26. 25 % ) than ZS 18 variety(ck).
