DNA C-values might be one of important indices in the evaluation of angiospermous invasiveness. To test this viewpoint, we compared DNA 1C-values and basic genome sizes in 3,676 angiosperms. The results suggest that:(1) the two nuclear values vary greatly among different groups, e.g., significantly higher in herbs than in trees, in monocots than in dicots, in perennials than in non-perennials;(2) the two nuclear values both have significant effects on plant invasiveness, especially in herbs, dicots, monocots, perennials, non-perennials, diploids, polyploids, Compositae, and Poaceae, while not significant in trees and Fabaceae.

DNA C值与被子植物入侵性密切相关，为考察应用DNA C值评估被子植物入侵性的可靠性和局限性，我们统计分析了全世界范围内3676种被子植物的DNA 1C值（配子未发生DNA复制时的染色体DNA含量）及基因组大小（单个染色体组的DNA 含量），结果表明：1）DNA 1C值和基因组大小在被子植物不同类群中差异极大，例如在草本植物中显著高于木本植物，单子叶植物显著高于双子叶植物，多年生植物显著高于非多年生植物；2）两项指标都与被子植物入侵性显著负相关，尤其是在草本植物、双子叶植物、单子叶植物、多年生植物、非多年生植物、二倍体、多倍体、菊科和禾本科中，然而在木本植物、豆科植物中其与植物入侵性无显著关系。
