| 摘 要： | 采用在NYDB上共培养酵母菌与绿霉菌Penicillium digitatum孢子、酵母菌防御接种沙糖桔果实后,挑战接种绿霉菌孢子的方法,研究了几株酵母菌对沙糖桔采后绿霉病的控制效果。结果表明,膜醭毕赤酵母Pichia membranaefaciens Hansen和深红酵母Rhodotorula rubra Demme Lodder显著抑制绿霉菌孢子萌发和芽管生长,有效减少沙糖桔绿霉病发生率及病斑数;添加2%NaHCO3可增强膜醭毕赤酵母的抗病效果,添加2%CaCl2对深红酵母的抗病效果有轻微的增强作用。4个拮抗剂组合均能提高沙糖桔果皮几丁质酶活性,以添加2%NaHCO3的拮抗菌制剂的几丁质酶活性最高。膜醭毕赤酵母和深红酵母可作为防治沙糖桔采后病害的拮抗菌,NaHCO3适合作为膜醭毕赤酵母制剂的添加剂,该制剂能有效地诱导几丁质酶活性增加,提高拮抗防病效果。 |

| Abstract: | The effects of 4 yeasts,Rhodotorula glutinis,Debaryomyces hansenii,Pichia membranaefaciens and Rhodotorula rubra,on the control of green mold(Penicillum digitatum) were evaluated on harvested Citrus reticulata cv.'Shatangju' fruit,by culturing both the yeast and the pathogen in nutrient yeast dextros agar(NYDB) suspension,and then inoculating the fruit with the cultures.Results showed that P.membranaefaciens and R.rubra apparently inhibited the germination and growth of P.digitatum spores.Adding 2%of NaHCO3... |
