摘要
爪耳木是滨海地区较理想的造林树种,具有一定的药用和经济价值。为保护爪耳木和开展爪耳木基因组学研究,利用流式细胞术对爪耳木进行染色体倍性测定和基因组大小评估。结果表明:爪耳木为二倍体植物,基因组大小约为921.11 Mb。
Lepisanthes unilocularis is an ideal afforestation tree species in coastal areas, and has certain medicinal and economic value. In order to protect Lepisanthes unilocularis and study the genomics of Lepisanthes unilocularis,chromosome ploidy of Lepisanthes unilocularis was determined and genome size was evaluated by flow cytometry. The results showed that Lepisanthes unilocularis was diploid with a genome size of 921.11 Mb.
