| 摘 要： | 以红树林植物红海榄Rhizophora stylosa和秋茄Kandelia candel为对象,研究了2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Phoma和拟盘多毛孢属Pestalotiopsis;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Shannon-Wiener多样性指数分别为1.7890和1.7473,Pielou均匀度指数分别为0.5260和0.5302。2种红树林植物的内生真菌显示出丰富的多样性。 |

| Abstract: | Endophytic fungal diversity on the mangrove plants Rhizophora stylosa and Kandelia candel was studied using the Shannon-Wiener and Pielou indexes. Results produced isolation and identification of 30 strains of R. stylosa with a colonization frequency of 100% and 27 strains of K. candel with a colonization frequency of 95.9%. The dominate species in R. stylosa was Phoma spp. and in K. candel was Pestalotiopsis spp. There were also significant differences（P0.05） in the colonization frequency of stems and leaves in R. stylosa and K. candel. For R. stylosa the Shannon-Wiener index （H′） was 1.789 0 and the Pielou index （J） was 0.526 0, whereas for K. candel H′ = 1.747 3 and J = 0.530 2. Thus, for both R. stylosa and K. candel endophytic fungi were plentiful. |
