摘要

摘要: 采用双层平板法和平板对峙法分别筛选对试验细菌指示菌和植物病原菌具有抑菌效果的内生拮抗真菌, 并通过形态特征观察和18SrDNA序列测定对拮抗真菌进行鉴定。结果表明:从单丛茶树中筛选出F15GEN、F15YE和LB35JING这3株内生拮抗真菌, 其中F15GEN对金黄色葡萄球菌抑菌圈直径为13.36mm, F15YE对枯草芽孢杆菌的抑菌圈直径为14.92mm, LB35JING和F15GEN对立枯丝核病原菌和梨腐烂病原菌的生长有抑制作用, F15YE对核桃叶枯病原菌的生长有抑制作用, LB35JING对茄腐镰刀病原菌的生长有抑制作用。经形态学和18S rDNA序列鉴定:F15GEN为斜卧青霉Penicillium decumbens, F15YE和LB35JING均属于青霉属Penicillium sp.。

Abstract: Endophytic fungi antagonistic against the selected bacteria and phytopathogens were first screened from the microbial samples collected from the single-clump tea plants using the double-plate and the flat-stand methods. Then, they were identified by their morphologies and 18SrDNA sequences. Three strains of the fungi, i.e., F15GEN, F15Ye, and LB35JING, were isolated. The diameter of the inhibition zone of F15GEN against Staphylococcus aureus was 13.36 mm, and that of F15YE against Bacillus subtilis 14.92 mm. In addition, LB35JING and F15GEN showed inhibition activities against Rhizoctonia solani and Valsa ambiens Pers, F15YE against Sphaerulina juglandis, and LB35JING against Fusarium. The 18S rDNA sequence of F15GEN identified it as Penicillium decumbens, while those of F15YE and LB35JING linked them to Penicillium sp.
