Abstract
【Objective】The purpose of this research was to study the effect of UV - C combined with 1 - MCP treatment on the resistance of black spot and enzymes activities related to the disease resistance of fragrant pear fruit during cold storage.The possible mechanism of the increasing disease resistance induced by UV - C and 1 - MCP was researched to provide the method for controlling effectively the growth of the black spot disease,which might reduce the incidence of disease and maintain good quality of the harvested fragrant pear fruit.【Method】Fragrant pear fruit was used as testing materials treated with 1 ppm 1 - MCP combined with UV - C 7.5 kJ/m~2 for 39 min,then,injury inoculation with Alternaria pp and was conducted and stored at low temperature(- 1℃,90%-95%RH) and normal temperature(20℃,80%- 85%RH)environment. The diameter of black spot and enzymes related withed disease resistance PAL,POD,CHT,GLU were measured during storage period.【Result】Fragrant pear treated with UV - C combined with 1 - MCP significantly enhanced the fruits defense enzymes PAL,POD,CHT,GLU activity.The diameter of black spot and disease incidence were inhibited by UV - C combined with 1 - MCP treatment.【Conclusion】Fragrant pear fruit treated with UV - C combined with 1 - MCP could effectively restrain the growth of the black spot disease,reduce the incidence of fruit,keep good quality and commodity value of fragrant pears.
