摘  要:
对荒漠草原区和山地区2种不同条件下的天然柄扁桃生长状况进行调查,通过初选和复选,采用主成分分析法,确定了天然柄扁桃优树指标及标准。结果表明:荒漠草原区入选优树的标准为灌丛高≥1.42 m,平均单枝基径≥1.82 cm,平均单枝分枝长≥24.01 cm,种子长径≥11.50 mm,叶面积≥1.03 cm2,平均单枝分枝数≥16.00条;山区入选优树的标准为灌丛高≥1.61 m,总结实量≥663个,平均单枝分枝长≥25.42 cm,种子长径≥11.69 mm,千粒重≥354.16 g,平均单枝分枝数≥13.00条。

摘  要:
In this paper,the natural Prunus pedunculata in different site of desert- steppe area and mountain area were investigated. The index and standard of plus tree of natural Prunus pedunculata were determined by the methods of preliminary selection,final selection and principle component analysis. The results show that in desert-steppe area,the standard for selection of plus tree was the shrub height≥1. 42 m,the average base diameter of single branch≥1. 82 cm,the average branch length of single branch ≥24. 01 cm,the length- diameter of seed ≥11. 50 mm,the leaf area≥1. 03 cm2,the average branch number of single branch≥16. 00 strips. In mountain area,the standard of selected plus trees is the shrub height ≥1. 62 m,the total number of fruit ≥663,the average branch length of single branch≥25. 42 cm,the length- diameter of seed≥11. 69 mm,the thousand kernel weight≥354. 16 g,the average branch number of single branch≥13. 00 strips.
