To investigate the potential of Pantoea agglomerans to control the major post-harvest diseases on Golden Delicious apples.
In laboratory trials, a high level of control of Penicillium expansum, Botrytis cinerea and Rhizopus stolonifer was obtained with P. agglomerans. In semi-commercial trials at 1degrees C in air and a low oxygen atmosphere, the reduction of blue mould was 81% and 100%, respectively, and control of grey mould was achieved equally with P. agglomerans and imazalil. In trials at 1degrees C and seven atmosphere conditions, maximum reduction in decay was 80% obtained at 3% O2-6% CO2. The population of P. agglomerans on apples followed the same pattern under all three atmosphere conditions studied.
Pantoea agglomerans could be used effectively on apples under a wide range of temperature and atmosphere conditions. SIGNIFICANCE AND IMAPCT OF THE STUDY Pantoea agglomerans can be used as a biocontrol agent on apples at 8 x 10(7) cfu ml-1, the same concentration as in pears. This will facilitate the application of this biological control agent by the growers in packing houses.
研究成团泛菌对金冠苹果主要采后病害的防治潜力。
在实验室试验中，成团泛菌对扩展青霉、灰葡萄孢和匍枝根霉有较高的防治水平。在1℃空气和低氧环境的半商业试验中，对青霉病的防治效果分别为81%和100%，成团泛菌和抑霉唑对灰霉病的防治效果相同。在1℃和七种气体环境条件下的试验中，在3%O₂-6%CO₂条件下腐烂率最大降低了80%。在所研究的三种气体环境条件下，苹果上成团泛菌的数量遵循相同的模式。
成团泛菌可在广泛的温度和气体环境条件下有效地应用于苹果。研究的意义和影响：成团泛菌可以作为一种生物防治剂，以8×10⁷ cfu ml⁻¹的浓度用于苹果，这与用于梨的浓度相同。这将便于种植者在包装厂应用这种生物防治剂。
