南昌地区蔬菜冰核活性细菌分离鉴定

摘要

Detection of INA (ice nucleation active bacteria) population on horticulture plants in Nanchang City was carried in this study. Through isolation and identification, 3 strains of high active INA were obtained among which were 2 strains of Erwina spp., 1 strains Pesudomonas spp. Among them Pesudomonas spp. and E. ananas were dominant population.%　　本研究对南昌地区蔬菜作物上的冰核活性细菌的进行分离鉴定，得到高冰核活性细菌3株，其中活性较强的初步鉴定为欧文氏菌属(Erwinia spp.)2株，假单胞菌属(Pesudomonas spp.)1株.初步了解了南昌地区蔬菜上冰核活性细菌的主要种群为假单胞菌属和欧文氏菌属.
