浚单0898生理特性研究

Physiological Characteristics of Xundan 0898

[目的]以浚单0898、郑单958为供试材料,研究不同生育期玉米品种的生理特性。[方法]测定2种供试材料的叶面积指数、叶绿素含量、地上部分干物质积累、子粒灌浆速率的动态变化规律。[结果]整个生育进程浚单0898的叶面积指数、叶绿素含量、地上部分干物质积累、子粒灌浆速率高于郑单958。[结论]浚单0898具有高产潜力,该研究为玉米适时管理提供科学依据。

[ Objective ] Taking Xundan0898 and Zhengdan958 as the test materials, we investigated the physiological characteristics of the materials at different growth period. [ Method ] The dynamic change laws of leaf area index, chlorophyll content, aboveground dry matter accumulation and grain - filling were carried out. [ Result] Leaf area index, chlorophyll content, aboveground dry matter accumulation and grain - filling at different growth period of Xundan0898 were higher than Zhengdan958. [ Conclusion] Xundan 0898 has high yield potential. This paper also provided the scientific basis for timely management of maize.
