| Abstract: | Leaf traits of 17 provenance resources in the major distribution region of the whole country were determined,and the genetic variation of Castanopsis hystix leaves from different producing areas was analyzed.The results showed that variance coefficient of 15 leaf traits ranged from 0.64%～26.09%,and significant difference of leaf traits existed among provenances of C.hystix,which indicated that variation of leaf traits in C.hystix provenances were abundant.The range of phenotypic differentiation coefficients among provenances were from 8.96% to 37.65% and the average value was 22.97%,which were lower than those within the provenances(77.03%).The correlation analysis of each leaf character in C.hystix Provenances suggested that leaf length,leaf width,left leaf width and leaf erea showed extremely significant positive correlation with altitude,while those showed extremely significant negative correlation with longitude and average annual temperature.The study had provided a certain basis for the classification,breeding and rapid propagation of nursery of C.hystix.; |
