Effects of Storage Environment on the Growth of Rhodotorula glutinis and Biocontrol of Alternaria alternata on Sweet Cherries
Abstract：The yeast antagonist Rhodotorula glutinis grew rapidly under the room temperature of 20～25℃.The concentration of 20% CO2 did not inhibit the growth of R.glutinis ,but there was negative relationship between the expansion of colony diameter and the CO2 concentrations(0-20%)(r=-0.899 9*～-0.938 3*).R.glutinis was more sensitive to high CO2 at low temperature (1℃) than at room temperature.Although it did not grow in the concentration of CO2 more than 15% at low temperature,R.glutinis grew rapidly after being transferred to room temperature for two days.CO2 at the concentration of 5% or 15% did not inhibit the disease incidence of Alternaria alternata on the sweet cherry fruit,but significantly inhibited the expansion of disease lesion.R.glutinis(108 cfu/mL)combined with 5% or 15% of CO2 could completely inhibit the growth of A.alternata on sweet cherry fruit.
