摘　　要：以金沙柚为试验材料,不套袋为对照,采用不同透光率纸袋在盛花后80 d进行套袋处理。分析套袋后不同发育时间油胞发育状况及成熟果皮挥发性成分含量变化。结果表明:套袋后油胞形态结构、横纵径无显著变化,但挥发性物质的种类和相对含量发生了变化。不套袋、单层白色纸袋和双层外红内黑纸袋处理分别检测到44、45和44种挥发性物质,均以萜烯类化合物为主,相对含量为75.77%~80.58%。两种套袋处理的萜烯类种类少于不套袋处理,三者共有萜烯类物质11种,都以D-柠檬烯相对含量最高,而双层纸袋处理D-柠檬烯高于不套袋和单层纸袋处理;两种套袋处理的醇类物质种类和相对含量高于不套袋处理,三者均以橙花醇和香叶醇为主;三者都包含两种检测到的醛类物质,并以柠檬醛为主,其中单层纸袋相对含量最高;酮类物质相对含量随光照减少而减少,其中不套袋以姜黄酮为主,单层和双层纸袋以圆柚酮为主;酯类中乙酸香叶酯相对含量最高,并且在各处理间差异很小;仅在单层纸袋处理中检测到微量的异香橙烯环氧化物。Using Jinsha pomelo as the experimental material and no bagging as the control,different light transmittance paper bags were used for bagging treatment of 80 days after blooming,the development status of oil cells and changes in volatile component content in mature fruit peels after bagging were analyzed at different developmental time.The results showed that there was no significant change in the morphology,structure,and diameter of oil cells after bagging,but the types and relative content of volatile substances changed.There were 44,45,and 44 volatile compounds detected in non bagged,single-layer white paper bags,and double-layer red and black paper bags,respectively,all of which were mainly terpenes with relative contents ranging from 75.77%to 80.58%.The types of terpenes in the two bagging treatments were less than those in the non bagging treatment.There were a total of 11 types of terpenes in the three treatments,with D-limonene having the highest relative content.However,the double-layer paper bag treatment had higher levels of D-limonene than the non bagging and single-layer paper bag treatments;The types and relative contents of alcohol substances in the two bagging treatments were higher than those in the non bagging treatment,and the three were mainly composed of nerol and geraniol;All three treatments contained two detected aldehydes,with citral as the main component,with single-layer paper bags having the highest relative content;The relative content of ketones was inversely proportional to the light intensity.Gingerol was the main ingredient without bagging,and naringin was the main ingredient in single-layer and double-layer paper bags;The relative content of acetate geranyl ester is the highest in esters of three treatments,and there was little difference among all treatments;Only trace amounts of isocyanate epoxide were detected in single-layer paper bag treatment.
