| 摘 要： | 通过组织分离空心莲子草叶片和茎秆，得到8种不同形态的菌株，鉴定菌株A、B、C分别为链格孢菌，镰刀菌和葡萄孢菌，D为未知真菌（没有产孢），E、F、O、H均为细菌。将上述分离获得的菌株分别接种PDA平板上培养3d后，用无菌水冲下，以喷雾器喷洒到健康的空心莲子草植株叶片上，记录发病情况，结果表明，菌株B和H对空心莲子草的生长有抑制作用，其中B的作用并不明显，发病率仅为4％，而H则对空心莲子草的生长有着较强的抑制作用，其发病率达到了59．6％。

| Abstract: | 8 kinds of different micro-organisms were attained by the use of tissue isolation method in philoxeroides hollow leaves and stems.Strains A,B and C were identified to be Alternatrina sp,Fusarium sp and Botrytis sp,Strain D is a kind of fungus;strains E,F,G,H are bacteria.These strains were inoculated to PDA stabs for 3 days and washed down,then they were insuffulated into hollow philoxeroides leaves,then recorded the case of deseases.The result showed strains B and H inhibited the Alternanthera philoxeroide... |
