Abstract:Using red globe as the experimental material，the effects of Botrytis cinerea on the main chemical components of epicuticular wax and storage quality of red globe stored at room temperature（25.0±0.5）℃were studied.Gas chromatography-mass spectrometry（GC-MS）was employed to analyze the main components of the epicuticular wax of red globe fruits.It was found that fatty acids and esters throughout the storage period were relatively high，followed by alcohols，alkanes，terpenoids，and aldehydes.As the storage time increased，alkanes，terpenoids，and aldehydes in the two groups of fruits decreased relatively.B.cinerea infection led to a decrease in the relative content of epicuticular wax components，thereby reducing the content of epicuticular wax.During storage，B.cinerea aggravated the weight loss and softening of red globe fruits and lowered soluble solids，titratable acid，total phenols and total flavonoids.Correlation analysis between the main components of wax and quality indicators revealed that epicuticular wax was an important factor affecting the storage quality of red globe.
