四倍体泡桐叶片显微结构观察及抗逆性分析
Observation on microstructure of leaves and stress tolerance analysis of different tetraploid Paulownia
摘要
Abstract
Microstructure characters of the leaves of tetraploid and diploid Paulownia (B4, Y4, N4 and M4 ; B2, Y2, N2 and M2) were observed and measured using scanning electron microscope, and the stress tolerance of tetraploid and diploid Paulownia were evaluated according to microstructure characters. The results showed that thickness of upper and lower epidermis, palisade tissue and leaf of tetraploid plants were larger than those of the diploid; cell tense ratio and ratio of palisade tissue thickness to sponge tissue thickness were also larger than those of the diploid; but spongy ratio and thickness of spongy were the opposite case. Three indexes (thickness of lower epidermis, spongy and palisade tissue ) were selected to evaluate stress tolerance of Paulownia by using the subordinate function value a-nalysis. The order of stress tolerance was M4 > Y4 > N4 > B4 > M2 > Y2 > N2 > B2.关键词
