| 摘 要： | 辣椒内生枯草芽孢杆菌(Bacillus subtilis) BS-莉和BS-1,对胶孢炭疽菌(Colletotrichum gloeosporioides)引起的辣椒苗和果炭疽病有良好的防治效果,菌株培养液对苗炭疽病的防效分别为81.5%~93.3%和66.1%~79.2%;对果炭疽病的防效分别为80.0%~100%和60.0%~100%,喷施菌株培养液后间隔24h以上接种病原菌的防病效果比两者同时接种的高。菌株外分泌物对病菌菌丝生长、分生孢子产生和萌发及附着胞形成均有明显的抑制作用。菌株菌体及其胞外分泌物均有防病作用,菌体可能起主导作用。另外,2菌株培养液浸种,对辣椒还有明显的促生效果。BS-2菌株的防病和促生效果均比BS-1高。

| Abstract: | Two strains of the endophytic Bacillus subtilis BS-2 and BS-1 isolated from foliage and stem of capsicum respec-
tively were used as biological control agents to control the anthracnose of capsicum. The results showed that the anthracnose
of the capsicum seedlings and fruits caused by Colletotrichum gloeosporioides was controlled effectively by these two strains,
with the control efficacy of 81.5%-93.3% and 66.1 %-79.2% for the seedling anthracnose, and 80.0%-100% and
60.0%-100% for the fruits anthracnose by BS-2 and BS-1 respectively. It also indicated that the growth of the capsicum
seedlings was promoted significantly by the two strains. The effects of the disease control and growth promotion of BS-2 were
better than those of the BS-1. The biological control mechanism of the two strains was discussed in this paper. |
