本研究首先对8种蔷薇属植物花苞期、半开期以及盛花期花瓣挥发性成分进行了

In this study, the volatile components of the petals of eight species of Rosa were detected and analyzed at the bud stage, half-open stage and full-bloom stage, and their floral fragrance release rules were explored, and the expression levels of key genes for monoterpene synthesis and the composition of floral fragrance components were analyzed. Correlation analysis was carried out to determine the DXR and NUDX1-1a genes play an important role in the synthesis of volatile components of Rosa petal monoterpenes in this study.

This study first detected and analyzed the volatile components in the petals of 8 species of Rosa plants during their bud, half bloom, and full bloom stages, exploring their floral aroma release patterns. The expression levels of key genes for monoterpene synthesis were correlated with the content of floral aroma components, and it was confirmed that DXR and NUDX1-1a genes play an important role in the synthesis of monoterpene volatile components in the petals of Rosa plants in this study.

In this study, the volatile components in petals of 8 species of Rosa were detected and analyzed at bud stage, semi-blooming stage and full flowering stage, and their floral release laws were explored. The correlation between the expression of key genes for monoterpene synthesis and the content of floral components was analyzed, and it was confirmed that DXR and NUDX1-1a genes played an important role in the synthesis of monoterpene volatile components in petals of Rosa in this study.
