Abstract: In order to reveal the dynamics of fruit growth and lipid accumulation regularity of Lindera glauca Blume, the quantitative character, lipid content and fatty acid composition of fruit were analyzed. The results showed that vertical and horizontal diameter of fruit, fresh weight of one hundred fruit and volume increased rapidly from fruit setting to the middle of June, which was relatively intensive fruit enlargement period. The fruit growth curves of vertical and horizontal diameter were fairly similar to‘S’model, whose coefficient of determination was more than 0.95 and statistical test of regression equation reached a highly significant level (P<0.001). Lipid accumulated mainly from late June to early September, during which time oil growth reached 73.23% of the total oil content of fresh fruit. In the process of growth and development, although the relative content of unsaturated fatty acid declined and that of saturated fatty acid increased, the relative content of unsaturated fatty acid was always higher than that of saturated fatty acid. Overall oleic acid was on a rising trend, and there was a strong negative correlation between oleic acid and linoleic acid as well as stearic acid (P≤0.05), whose correlation coefficients were -0.801 and -0.843, respectively. In addition, certain amount of capric acid and lauric acid, which were widely used in industry, were detected in fruit oil of Lindera glauca.
