摘　　要：本研究选用3个纤维颜色不同的棉花近等基因系-绿色棉、棕色棉和白色棉为材料,研究参试材料的主茎功能叶片在整个生育期的生理特性变化,并对生理指标与产量因素进行相关性分析。结果表明:整个生育期2种彩色棉的净光合速率均低于白色棉;除吐絮期外,彩色棉总叶绿素含量、蔗糖合成酶和蔗糖磷酸合成酶活性均低于白色棉;净光合速率与单株铃数、单铃重及单株产量呈显著正相关;总叶绿素含量与单铃重、单株产量呈极显著正相关;蔗糖磷酸合成酶活性与单铃重呈极显著正相关,与单株产量呈显著正相关。本研究结果将为彩色棉高产品种选育提供理论依据。In this study,three cotton near isogenic lines with different fiber colors,green cotton,brown cotton and white cotton,were selected as materials to study the changes of physiological characteristics of main stem functional leaves in the whole growth stages,and the correlation between physiological indexes and yield factors was analyzed.The results showed that the net photosynthetic rate of two colored cottons in the whole growth stages was lower than that of white cotton,and the total chlorophyll content,sucrose synthetase and sucrose phosphate synthetase activity of colored cotton were lower than that of white cotton except for the boll opening stage.The net photosynthetic rate was positively correlated with the number of boll per plant and the weight of boll,and yield per plant.The chlorophyll contentwas positively correlated with boll weight and yield per plant.Sucrose phosphate synthetase activity was positively correlated with the weight of boll and yield per plant.The results of this study will provide a theoretical basis for the breeding of high-yield varieties of colored cotton.
