摘要： Aroma profiling peach flowers can improve the landscape and ecological value of the surrounding environment. In order to preliminarily explore and screen the flower aromas of peach germplasms, the floral aroma profiles of 50 peach germplasms were analyzed by electronic nose detection. The clustering results from ten sensors showed that it was possible to identify each peach blossom aroma type. 'Gansutao2' was separately classified as cluster I; 'Yuntaishanshantao', 'Dazhuanggansutao', and 'Zhouxingshantao' as cluster II; 'Xinjiangpantao' and 'Xinjianghuangrou' as cluster III; and the remaining germplasms as cluster IV. The flower aromas of clusters I, II, and III were different from that of cluster IV and were mainly highlighted by the significant differences in the response values of the three main sensors, which were W1S (methane), W1W (hydrogen sulfide), and W5S (nitrogen oxides). The principal component analysis and significance analysis of the sensor response values showed that 'Hua3', 'Hongfenjiaren', and 'Yuntaishanshantao' had special flower aromas. The response values of these three varieties produced by the W1S, W1W, and W5S sensors and two aromatic sensors, W2W (aromatic components and organic sulfides) and W3S (methane-aliph), were significantly different from most of the other germplasms. The 'Yuntaishanshantao' response values produced by the five sensors' were low, which showed that it had a light aroma, while the 'Hongfenjiaren' and 'Hua3' values were high, which showed that they had strong aromas. The results from this study provided basic data that could be used to screen peach germplasms with obvious floral aromas, cultivate new varieties with strong aromas, and aid the development and utilization of peach floral aroma substances.
