摘要: The volatiles of 75 plums belonging to five species and one interspecific hybrid were investigated by headspace-SPME-GC-MS; 88 volatiles were identified. Primus salicina and its hybrids had much more compounds and higher contents of volatiles than Primus domestica and other three Chinese wild species. Aldehydes were the dominant volatiles in P. domestica and Prunus spinosa while esters were the major volatiles in P. salicina, P. salicina hybrids and Prunus ussuriensis fruits. Regarding terpenoids and alcohols, they were relatively high in several P. salicina cultivars, P. salicina hybrids and P. spinosa, and in Prunus cerasifera, respectively. All the plum germplasms could be divided into three groups via principal component analysis: (1) nine cultivars of P. salicina with high ester content, (2) nine Chinese cultivars and one P. salicina hybrid with ester content and two terpenoids, and (3) the rest of the cultivars and three Chinese wild species without characteristic volatiles.
