摘要
以海南红树林植物红海榄和秋茄为对象,研究了两种植物的内生真菌的多样性。结果表明:红海榄和秋茄的枝、叶中分别分离到内生真菌30株和27株,内生真菌的优势属分别是茎点霉属和拟盘多毛孢属;同种植物的枝和叶中内生真菌的定殖率差异显著;红海榄和秋茄内生真菌的多样性指数分别为1.7890和1.7473,均匀度指数分别为0.5260和0.5302。两种红树林植物的内生真菌显示出丰富的多样性。
Diversity of endophytic fungi from mangrove plants Rhizophora stylosa and Kandelia candel in Hainan Province were investigated. The results showed that 30 strains and 27 strains were isolated and identified from the twigs and leaves of two plants,respectively. The dominate genera were Phoma in R.stylosa and Pestalotiopsis in K.candel. Colonization frequencies varied significantly between stems and leaves in the same plant. In R.stylosa and K.candel,the Shannon-Wiener index was 1.7890 and 1.7473 respectively,and the evenness index was 0.5260 and 0.5302 respectively,which indicated that the endophytic fungi are rich in both mangrove plants.
