Abstract

Abstract: With Shine Muscat grape as the research object, four treatments of fruit thinning were conducted, including 100, 80, 60 berries and no fruit thinning for each grape bunch. And the influences on the berry weight, longitudinal and transverse diameter, soluble solid, soluble sugar, titrable acid, and soluble protein content of Shine Muscat grape fruit were studied. The results showed that when the thinning amount of the berry was 100 and no fruit thinning,the grape bunch was crowded and each berry was small, while the content of the soluble solid was low. When the thinning amount of the berry was 80, the berry size was medium, the soluble solid and soluble protein content was high. When the amount of the berry was 60, the berry was uniform, without any size differences, the single berry weight was the heaviest, and the soluble solid content and economic benefit were higher. Considering the comprehensive benefits, the best thinning amount of Shine Muscat grape was 60 berries for each grape bunch in Hubei Province.

Key words: Shine Muscat grape, load capacity, fruit thinning, fruit quality
