气候因子与脐橙果实糖、酸含量的灰色关联度分析

The Gray System Analysis of Climatic Factors to the Organic Acid and Sugar Content of Navel Orange (Citrus sinesis Osbeck) Fruit

对 11个主要气候因子与脐橙果实糖、酸含量的灰色关联度分析研究 ,结果表明 :对果实糖含量影响最大的气候因子是年均温 ,其次是幼果期 (5月、6月 )和成熟期 (10月、12月 )的月均温 ;对果实有机酸含量影响最大的则是年降雨量、年均温 ,其次是果实生长期的月均温 ,尤以脐橙果实有机酸下降期 (9月 )和有机酸合成期 (5月、6月 )

By the gray system analysiag of 11 climate factors to the fruit acid and sugar content, the results show that the factors which influence the sugar content more seriously is the annual average temperature; the second is the average temperature of May, June, October and December. The factors which seriously influence the organic acid content are annual rainfall and annual average temperature. The second is the average month temperature of the fruit developing. Especially the greatest influence factors are the synthesis period of organic acid (the average temperature of May and June) and the decomposing period of organic acid (the average temperature of September).
