摘要
本文对3个杂交水稻及其亲本灌浆期叶绿体诱导荧光动力学光谱、活体叶片光合放氧速率、叶绿体低温(77k)荧光发射光谱与二磷酸核酮糖羧化酶的活性研究结果表明:强优势的杂种均表现出高活性和高效率,而弱优势的杂种则相反。并对光合优势的生理机制进行了分析。
In this paper the kinetics of fluorescence induction and low temperature(77k) fluorescence excited in chloroplasts, in vivo photosynthetic O(?) release rate and ribulose-1, 5-biphosphate carboxylase in leaves of hybrids and their parents at filling stage were studied. The results indicated that the vigorous hybrids has higher activity and efficieney. The physiological mechanism of heterosis in photosynthesis was diseussed.
