| Abstract: | Three local avocado strains in Hainan were used as the test materials. White paper bags and yellow outside and black inside kraft paper bags were selected to bag avocado fruits, and non-bagging was used as the control. 100 days after bagging, samples were collected when avocado was mature to determine the appearance and internal quality of fruit. The effects of bagging on fruit quality and fatty acid composition of avocado were observed and determined. Comprehensive evaluation was carried out by the principal component analysis. The results showed that the skin of fruits treated with yellow outside and black inside kraft paper bags turned yellow, and the skin color of fruits treated with white paper bags had little difference from that without bags. Bagging had no significant effect on the appearance indexes of single fruit quality, fruit transverse diameter, fruit longitudinal diameter, fruit shape index, pulp weight, seed quality, seed longitudinal diameter and seed transverse diameter of avocado fruit, but bagging could reduce the harm of diseases and pests, reduce the damage of branch and leaf friction to avocado fruit surface and improve the appearance quality of avocado fruits. Bagging had no significant effects on the internal indexes of edible rate, water content and soluble sugar content of avocado fruit, but bagging could significantly improve the contents of vitamin C, soluble protein, total phenol and total flavonoids. Through the determination of 8 fatty acid components in avocado pulp, the comparative analysis showed that bagging had no significant effects on the fatty acid components of avocado fruit, but could improve the relative content of unsaturated fatty acid in avocado fruits. Through principal component analysis, the score of nine treatments on three principal components was obtained. After calculating the score according to the expression, the fruit quality traits of white fruit bags were the best among the three bagging treatments of each strain. In conclusion, fruit bagging during the growth and development of avocado can provide a new microenvironment for its growth and development, reduce the impact of various external adverse factors on fruit development, and improve the appearance and internal quality of fruit. This study preliminarily screened out the white paper bag suitable for the bagging of avocado, which can provide reference for growers in the production of avocado, so as to better meet the demand for high-grade fruits in the domestic and foreign markets. |
