摘要

In this paper, the pollen morphology characteristics, chromosome karyotype characteristics, floral pigments, and scents components of 15 species and hybrids of Syringa L. were obtained by means of scanning electron microscopy, root tips quash method, HPLC–MS, and GC–MS, and the 15 species and hybrids of Syringa L. were clustered separately with each index. Results show that the 15 species and hybrids of Syringa L. are clustered into four different groups separately by each index. In morphological taxonomy, S. microphylla Diels and S. microphylla ‘ShuangJi’, which belong to the Ser. Pubescentes family, original and hybrid species, most varieties of Ser. Syraega are basically cluster into the same group, which is consistent with morphological taxonomy. The findings indicate that the aforementioned four indicators are significantly related to the morphological classification of Syringa L. Among them, the clustering results of pollen morphology were the most consistent with morphological classification. The relationship between the above four aspects and the morphological classification of Syringa L. groups has not been reported in previous related researches, especially indicating the relationship between microscopic morphological indicators, specific physiological components and Syringa morphological classification. The research results have novelty, scientificity and comprehensiveness.
