摘　　要：在大田栽培条件下,研究了杂交棉豫杂35、中棉29、标杂A2、标杂A1、经杂2号的主茎叶的光合特性及其产量和纤维品质,结果表明:豫杂35由于其叶片功能期Pn较高,且衰老慢,其叶片的Pn、Fv/Fm和ФPSⅡ日变化幅度又较小,对强光利用能力强,全天光合速率较高,从而获得显著高的最高产量;中棉29、标杂A2、和经杂2号获得较标杂A1显著高的产量;标杂A1由于叶片早衰且叶片光合性能相对较差,而产量最低,纤维品质较差。The photosynthetic characteristics and yield ＆ fibre quality was studied under field condition with five hybrid cotton varieties. The results showed that Yu-Za 35 indicated higher photosynthetic rate （Pn） and smaller diurnal change of Pn, Fv/Fm, φPS Ⅱ in leaves , consequently having higher ability of utilize powerful light and the highest yield was harvested compared with other varieties. The yield of Zhong mian 29,Biao za A2 and Jing za 2 was higher significantly compared with Biao za A1. The yield of Biao za A1 was lowest because of senescence-early and lower Pn of leaves.
