Character Performance and Clustering Analysis of 19 Different Xanthoceras sorbifolia Germplasm Resources in Xinjiang
The growth characteristics and influence factors of 19 X.sorbifolia germplasm resources at seedling stage were studied by the sowing and seedling raising test to provide the scientific basis for further popularization and application of X.sorbifolia.Results: The height, ground diameter and crown width of Mudanjiang, No.1, Kun 6 and Jing 7 of X.sorbifolia germplasm resources at different growth periods are the best but the height, ground diameter and crown width of Jing 1, Yi 22 and Hong 5 X.sorbifolia are poor among 19 X.sorbifolia.There is an obvious difference in leaf number among 19 X.sorbifolia germplasm resources and the variation range of leaf number is 12~35.The leaf number of Mudanjiang is the highest (35 leaves)and significantly higher than other germplasm resources.The leaf number of Jing 22, Hongbu 4 and Jing 18 is the lowest.19 X.sorbifolia germplasm resources can be divided into four groups by clustering analysis.The comprehensive performance of Group Ⅰ(Mudanjiang) is the best and the growth vigor of Group Ⅳ is poorer.The daily average temperature is positively related to height and crown width of X.sorbifolia very significantly and daily average relative humidity is negatively related to ground diameter of X.sorbifolia significantly.The average wind velocity has no correlations with height, ground diameter and crown width of X.sorbifolia.
