Abstract: This study analyzed the grape senescence conditions of eight cultivars postharvested and relative expression of related genes. It was found that the Euramerican hybrids‘Fujiminori’，‘Shinano Smile’and‘Xiyanghong’with higher relative expression levels of VvNCED1，VvACO1 and VvPG genes were analyzed the obvious decline of physiological index，such as pulling resistance，turgor pressure and berry dropping rate increased rapidly. Their storability was poor. However，Eurasian hybrids‘Yellow Italy’，‘Red Globe’and‘Manicure’with high expression of VvPOD2 and VvMnSOD were analyzed that the decline of physiological index was slow，berry dropping rate increased slowly and storability was eligible. The research illustrated that the relative expression of aging-related genes can reflect the storage capacity.
