摘  要:
在大田栽培条件下,研究了短季棉豫早73、豫早06、豫早08、中棉37和中棉30的主茎叶片的光合特性及其单株产量和纤维品质。结果表明:豫早06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,从而获得最高产量;豫早73和豫早08,由于其叶片的Pn、Fv/Fm和ФPSⅡ日变化幅度比中棉30的小,对强光利用能力强,全天光合速率较高,而获得较中棉30显著高的产量;中棉37由于其叶片功能期Pn较高,且衰老慢,也获得较中棉30显著高的产量;中棉30由于其叶片光合性能相对较差,而产量最低。

摘  要:
The photosynthetic characteristics and yield and fiber quality of five short-season cotton varieties were studied under field condition. The results were as the follows: Yuzao 06 indicated higher photosynthetic rate(Pn) and smaller diurnal change of Pn, Fv/Fm and ФPSⅡ in leaves, and gave the highest yield compared with other varieties; Yuzao 73 and Yuzao 08 showed smaller diurnal change of Pn, Fv/Fm, ФPSⅡ and higher Pn in leaves, and yield was higher significantly compared with Zhongmian 30; Zhongmian 37 indicated higher Pn in leaves, and its yield was higher significantly compared with Zhongmian 30; Zhongmian 30 indicated poor photosynthetic characteristics with the lowest yield.
