摘要：

从保存的以及从桃果实表面和伤口上分离获得的拮抗菌中筛选出了10余株能有效地防治采摘后果实病害的拮抗菌.结果表明,保存的洋葱伯克霍尔德氏菌(Burkholderia cepacia)、季也蒙假丝酵母(Candida guiliermondii)、柠檬形克勒克酵母(Kloeckera apiculata)、汉逊德巴利酵母(Debaryomyces hansenii)、枯草芽孢杆菌(Bacillus subtilis)B-912等5种拮抗菌对甜樱桃褐腐病都表现出显著的抑制效果,其中枯草芽孢杆菌、季也蒙假丝酵母可完全抑制病害的发生;季也蒙假丝酵母和柠檬形克勒克酵母能有效地防治核果类果实采摘后软腐病.从桃果实表面分离到的隐球酵母(Cryptococcus albidus (Saito) Skinner)和丝孢酵母(Trichosporon sp.)能防治苹果灰霉病和青霉病,而从桃果实伤口处分离到的膜醭毕赤酵母(Pichia membranefaciens hansen)则对核果类果实软腐病有较好的抑制作用.在分离的细菌中,B8对褐腐病和软腐病的抑制作用最好,Bw6和Bw7可抑制褐腐病的发生,Bw10则对软腐病有显著的抑制作用.
