The results were as follows:(1) Seeds of 80 species or subspecies could be classified into two groups. Group Ⅰ included the seeds of Gramineae, Cyperaceae, Polygonaceae and Amaranthaceae, and Group Ⅱ included the seeds of Compositae, Euphorbiaceae, Brassicaceae and Umbelliferae.(2) Only FTIRs of the seeds of Brassicaceae were clustered together in the dendrogram,while those of the other families all appeared farraginous.(3) Among FTIRs of the 11 groups of the congeneric species,8 groups were clustered with other genus species, and 6 out of 7 groups of conspecific seeds appeared farraginous in the dendrogram.

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。
