摘  要：
采用固相微萃取结合气质联用仪(SPME–GC–MS)检测了元宝枫(Acer truncatum Bunge.)叶片春、夏、秋季挥发物的释放,同时利用CIRAS-Ⅱ型光合仪测定了其主要光合参数,分析了元宝枫挥发物的主要成分、季节变化规律及其影响因素。结果表明,元宝枫挥发物的主要成分是酯类,其次是醇和醛类及萜烯类物质,主要物质有3–己烯醛、3–己烯醇、乙酸叶醇酯、乙酸己酯和β–石竹烯。挥发物总峰面积为春季>夏季>秋季,主要物质的释放规律不同,挥发物总峰面积与气孔导度呈显著正相关,与温度、净光合速率及蒸腾速率的变化趋势一致,与光合有效辐射的变化不一致。

摘  要：
Volatile compounds emitted by Acer truncatum were collected and analyzed by SPME– GC–MS in spring,summer and autumn,and the photosynthetic characteristics of the species were measured by CIRAS-Ⅱ photosynthetic apparatus.The main components,seasonal change and influencing factors of volatile compounds were analyzed.The results showed,the main volatile compounds included esters,followed by alcohols,aldehydes and terpenes,and the main components were 3-hexenal,3-hexen-1-ol,3-hexen-1-ol,acetate,acetic acid hexyl ester and β-caryophyllene.The total volatile compounds concentration varied with seasons,presenting a tendency of spring>summer>autumn,and the main components showed different releasing patterns.The correlation analysis indicated that there was a positive correlation between the total volatile compound and the stomatal conductance at the significant level.And the total volatile compound was accord with temperature,photosynthetic rate and transpiration rate,but not accord with the PAR.
