Comparative Study on Biological Characteristics between iploid and Polyploid Siraitia grosvenorii
摘要
Abstract
Compared with the diploid, biological characteristics of diploid and polyploid Siraitia grosvenorii were studied and polyploidy Siraitia grosvenorii included triploid and tetraploid.The results showed that the basal diameter, stem width, leaf length and width, leaf area, leaf thickness, stomatal length and width, guard cell length and width, petal length and width, ovary vertical diameter and horizontal diameter were 4X＞3X＞2X,and the differences of most biological characteristics were significant between different ploidies (P ＜ 0.05). On the contrary,the trend of stomata density was 2X＞3X＞4X,and the differences were also remarkable between different ploidies (P ＜ 0.05). Because polyploidy Siraitia grosvenorii showed largness,it could be identified fastly,and used to breed Siraitia grosvenorii.关键词
