Comparative study of volatile components from male and female flower buds of Populus × tomentosa by HS-SPME-GC-MS
The differences of volatile components in male (MFB) and female flower buds (FFB) of Populus × tomentosa were analysed and compared by HS-SPME with GC-MS for the first time.A total of 34 compounds were identified.Two clusters were clearly divided into male and female by hierarchical clustering analysis.Both the male and female flower buds showed methyl salicylate (22.83% and 24.09%,respectively) and 2-hydroxy-benzaldehyde (10.05% and 12.41%,respectively) as the main volatile constituents.The content of 2-cyclohexen-1-one,benzyl benzoate,and methyl benzoate in FFB was remarkably higher than in MFB.In contrast,the content of ethyl benzoate in MFB was greater than that in FFB.The phenomena showed the characteristic differences between MFB and FFB of P.× tomentosa,which enriched the basic studies on dioecious plant.
