Correlation between Characters of Xanthoceras sorbifolia Cone

HOU Yuan-kai; HUANG Lin; ZHOU Zhong-hui

Xanthoceras sorbifolia provenances were obtained in their main districts, and some cone characters were tested which includes cone diameter(A), cone length(B), pericarp thickness(C), fruitstalk diameter(D), single cone weight(E), pericarp weight(F), seed weight(G), number of seed room(H), seed number(J), rate of seed of cone(K). From the analysis of those characters, it was found that the indexes of characters of single cone weight(E), seed weight(G), pericarp weight(F) had large disparities, and the indexes of characters of cone diameter(A), cone length(B), pericarp thickness(C), fruitstalk diameter(D) had small disparities. There were linearly positive correlations between indexes of characters, the relative coefficient of factors with A is E＞B＞F＞G＞D＞J＞C; the relative coefficient of factors with B is E>G>F>A>J>D>C;the relative coefficient of factors with C is J＞G＞E＞B＞F＞A;the relative coefficient of factors with D is E＞G＞F＞A＞B＞J;the relative coefficient of factors with E is F＞G＞A＞B＞J＞D＞C; the relative coefficient of factors with F is E＞G＞A＞B＞J＞D＞C;the relative coefficient of factors with G is E＞F＞B＞A＞J＞D＞C.
