Phenotypic Characteristics Research on Correlation of Saussurea balangshanensis Populations to Altitude
The research on correlation of 10 Saussurea balangshanensis populations to different altitude which distributed on Balang Mountain in National Natural Reserve of Sichuan Wolong.The results indicated the species richness of S.balan-gshanensis populations and number of target plant all showed an invert-U-shaped curve,which had significantly(P＜0.05)and most significantly(P＜0.01)quadratic regression equation with the altitude.There was a significantly positive correla-tion between petiole length and altitude(P＜0.01),a very significanty negative correlation between flower diameter and altitude(P＜0.01),none correlation between number of flowers and altitude.The results provide a important reference for exploits and studies on conservation in the future.
