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1.789 0和1.747 3,Pielou均匀度指数分别为0.526 0和0.530 2。2种红树林植物的内生真菌显示出丰富的多样性。表4参22Abstract: 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(P<0.05) 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.[Ch,4 tab. 22 ref.]
