- 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 highyield 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.
