Study on the species and ecological character of mangrove pathogenic fungi in Guangxi
摘要
Abstract
The species and ecological character of mangrove pathogenic fungi in three areas (Shankou,Qinzhou and the estuary of Beilun in Guangxi) are reported. Among fourteen genus twenty-six species(isolates)of mangrove pathogenic fungi that are mainly Colletotrichum,Pestalotiopsis,Alternaria and Phyllosticta were identified. And the richenss index(DMA)、species diversity index(H')and evenness index(JSW)of the identified pathogenic fungi species in three areas are 2.826 5～4.700 4、0.971 8～ 1.276 8 and 0.900 5～0.915 8 respectively. In Shankou,there are only twelve species,less than other two areas,so the DMA and H' are the minimun accordingly. Meanwhile,the most important character in the distribution of the mangrove pathogenic fungi is that the variety in high-tide land is more than that in low-tide land,and the most variety is found in the area round estuary. The pathogenic fungi infect chiefly the top of the mangrove plant. Diseases occur mostly on leaves,then on the tip of branch,and rarely on the root and stem. Most diseases occur on Aegicera corniculatum and Excoecaria agallocha,however,few diseases occur on Rhizophora stylosa and Acanthus ilicifolius.关键词
