摘要: 为分析小麦新品种‘烟农5158’的光合生理基础,以其亲本之一‘鲁麦14号’为对照,研究了‘烟农5158’与其亲本‘鲁麦14号’之间的生物学特点及灌浆期的光合生理指标。结果表明:‘烟农5158’与‘鲁麦14号’相比,具有更好的株型结构和更大的产量潜力;花后不同时期籽粒的灌浆进程和灌浆速率、旗叶的净光合速率、叶绿素含量、花后旗叶蒸腾速率、旗叶原初光化学效率的日变化、旗叶最大和实际光化学效率、PSⅡ实际光化学效率、非光化学能量耗散等光合生理指标都优于对照‘鲁麦14号’。这是‘烟农5158’具有高产特性的生理原因之一。

Abstract: To analysis Photosynthetic Physiological basis of new wheat variety ‘Yannong 5158’, the physiological characteristics during grain filling stage and biology characteristics of it were studied by using one of its parents ‘Lumai 14’ as control. The results showed that ‘Yannong 5158’ had better plant type structure and higher yield potential than ‘Lumai 14’. The photosynthetic physiological indexes during filling stage, such as filling process and rate in grain, net photosynthetic rate in flag leaf, chlorophyll content, transpiration rate in flag leaf after blooming, day changes of primary photochemical efficiency in flag leaf, the largest and actual photochemical efficiency in flag leaf, actual photochemical efficiency of PSⅡ, non-photochemical energy dissipation were better than the control. This was one of the physiological reasons with high yield characteristics of ‘Yannong 5158’.
