摘要:
?2009～2010年，以普通大豆品种九农21为对照，比较了其与高产品种长农13和吉育88的生长动态、主要农艺性状及产量，并对形态指标和产量构成因素进行了典型相关分析。结果表明：高产品种的叶面积指数、地上部生物量、根系指标（根系活力、伤流量、根系体积和干重）、产量以及株高、单株荚重、单株粒重和百粒重等主要农艺性状均高于对照品种，但主茎节数和分枝数低于对照；通过典型相关分析发现，单株粒重与R5期根系体积呈显著正相关，而与R6期叶面积指数呈显著负相关，表明合理调控鼓粒期的群体结构，有助于增产。
Abstract:
?In 2009-2010,taking ordinary soybean cultivar(Jiunong 21)as control,growth dynamics(leaf area index,aboveground biomass,root indexes),major agronomic traits and yield of highyield cultivars(Changnong 13 and Jiyu 88)were compared,and canonical correlation analysis was made between the morphological index and yield components.For high-yield soybeans,LAI,aboveground biomass,root indexes（root activity，bleeding sap volume,root dry weight and volume）,yield and main agronomic traits such as plant height,pod weight per plant,seed weight per plant and 100-seed weight were higher,while main stem nodes and branches were less than control.Canonical correlation analysis showed seed weight per plant was significant positively correlated with root volume at R5 stage,and significant negatively correlated with LAI at R6 stage.The result indicated that a reasonable regulation on soybean population structure at seed filling period would be helpful to increase yield.
