摘    要:以紧凑型高产潜力玉米品种先玉335、郑单958和普通平展型玉米品种豫玉22、农大518为试验材料,对其群体叶面积指数、光合势、净同化率、干物质积累量及产量在全生育时期内的动态进行分析。结果表明,两个高产潜力玉米品种的群体叶面积指数、光合势和干物质积累总量均高于平展型玉米品种;群体光合生产率在不同生育时期表现不同,生育前期豫玉22和农大518的净同化率高于先玉335和郑单958,出苗90d后呈现相反趋势;产量与吐丝后干物质积累量呈现显著正相关,与各群体生理参数并非全部呈现显著差异。作物产量的形成过程是数量性状和质量性状的综合作用结果,最佳产量水平群体不是某项生理指标的突出表现,而是决定于各项生理指标的适度。

关 键 词:玉米  群体生理参数  干物质  产量

Abstract:Two types of maize cultivars, high yield potential maize (Xianyu335 and Zhengdan958) and normal maize (Yuyu22 and Nongda518) were chosen as materials, the canopy physiological parameter including leaf area index, leaf area duration, the net photosynthetic rate, dry matter accumulations and yield were analyzed in maize with different types. The result showed that the leaf area index, leaf area duration and the total dry matter accumulation of maize with upright-leaf type were higher than normal maize. The net photosynthetic rate of Yu22 and Nongda518 was higher than Xianyu335 and Zhengdan958 in the early growth stage. Emergence showed the opposite trend after 90d; yield and dry matter accumulation after silking showed a significant positive correlation with physiological parameters that not all groups showed a significant difference. The formation of crop yield and quality traits were quantitative trait combination of results, the best level of production groups was not a physiological indicator of outstanding performance, but decided at the appropriate physiological indicators.
Keywords:Maize  Canopy physiological parameter  Dry matter  Yield
