Individual differentiation and biomass characteristics of young Sapindaceae mukorossi forest——Superior individual selection techniques of S.mukorossi
摘要
Abstract
Among the young forest of Sapindus mukorossi Gaertn,there is significant individual variation,and the differentiation degree is canopy widthsground diameter plant heightbranch number.Among phenotypes,there exists significant correlation.The plant total biomass consists of the root biomass accounting for 26.00%,stem biomass accounting for 68.32%,and leaf biomass accounting for 5.67%,and stem is the main harvest part of biomass.Through stepwise regression,the regression model of S.mukorossi Gaertn's total biomass to ground diameter,plant height and canopy widths has been set up,the regression model is: y=612.2606+91.6329x1-72.88x2-87.1238x3.The correlation coefficient r is 0.9825,which illustrates that conducting individual biomass evaluation by the selective factors of S.mukorossi Gaertn's canopy widths,ground diameter and plant height can realize the effect of evaluation and selection through the final goal of total biomass.关键词
