摘　　要：本试验研究杂交棉中棉63号和常规棉2号优系的吸收光合有效辐射（APAR）和光合有效辐射截获量（FAPAR）随生育期的变化特征及与产量的相关关系。结果表明：棉花2品种群体APAR和FAPAR在盛蕾期较低，开花结铃期达到最高值，它们的变化趋势与棉株昀生长发育进程相一致。杂交棉和常规棉的APAR和FAPAR与产量均达到极显著的线性相关，且杂交棉与常规棉相比较，APAR和FAPAR与产量的相关性较高。Research the relationship between absorbed photosynthetic active radiation （APAR） and photosynthetic active radiation intercepted quantity （FAPAR） with production of hybrid cotton No.63 and conventional cotton No.2. Results showed that： the two varieties＂ APAR and FAPAR were lower in bud stage, highest in flower and boll period, and their change tendency was consistent with the process of growth and development of cotton. The APAR and FAPAR of both varieties had significant relationship with the production, and the hybrid cotton were more significant than conventional cotton.
