Abstract The 11 morphological and anatomic traits in fruit twist direction, spine/wing texture, and twist degree, etc. of 15 species of Calligonum L. from China were studied by use of principal component analysis (PCA). Results showed that the contribution of the first principal components accounted for 29.704%, among which sparse degree of fruit spine, trench depth, arris raised degree are the main factors influencing fruit characters; the contribution of the second principal components accounted for 25.598%, which included base width, fruit type. In PCA analysis, factors affecting fruit characters can be divided into four classes: the first class including spine/wing row number of fruit, sparse degree of fruit spine, arris width; the second consisting of fruit type, fruit twist direction, and twist degree; the third involving spine/wing texture, hard and thick degree, trench depth, arris raised degree; and the forth comprising base width. Analysis of the first, the second and the third principal components disclosed that the fruit of Calligonum L. grows to be shallow trench and narrow arris, and the fruit spine density to be intense so as to adapt to desert environment.
