| Abstract: |
| In order to learn fruit characters, and fatty acid composition and content of Olea europaea after implanting to China, twelve fruit characters of Olea europaea of six varieties were analyzed by principal component analysis and the correlations between them and oil content or fatty acid compostion were studied, including Leccion, Manzanlia, Arbequnia, Picholine, Zhongshan 24# and Chenggu 32#. The results showed that coefficient of variation in weight of fruit pulp was the maximum and it was the minimum in rate of fruit pulp. Picholine was the maximum in types and values in cofficient of variation of fruit character, and Arbequnia was the minimum in coefficient of variation of fruit character. There were highly singnificant correlation between fruit weight and fruit diameter and weight of fruit pulp between fruit height and weight of fruit stone, between fruit diameter and pulp thickness and weight of fruit pulp between pulp thickness and weight of fruit pulp, and the correlation coefficients were above 0.900. It indicated that there were close correlations among their fruits morphological characteristics. The twelve fruit morphology characters could be simplified into two main characters, rate of nucleation and weight of fruit stone, which represented all information. The fatty acid compositions of oils from fresh fruit and dry fruit had small differences, and the content of polyunsaturated fatty acids in dry fruit oil decreased. The correlation analysis with fruit characters showed that the content of linolenic acid in Olea europaea oil was highly significant or significant positively correlated with fruit weight, diameter of furit stone, weight of fruit pulp, weight of fruit stone, fruit diameter and pulp thickness. The content of palmitoleic acid was highly signicant or signicant negative correlated with oil content in dry fruit, fruit shape index and stone shape index. It indicated that partial component of unsaturated fatty acids in Olea europaea oil was related with the fruit characters. |
