Abstract: In order to provide the theoretical basis and scientific reference value for grape ploidy breeding, the physiological and biochemical indexes of different varieties of diploid and tetraploid were determined. The results showed that (1) The tetraploid of different grape varieties showed a great characteristic with the diploid in botanical characteristics. (2) The tetraploid content of proanthocyanidins in leaves of different grape varieties was higher than that of diploid; (3) T The tetraploid of chlorophyll content in leaves of different grape varieties was higher than that of diploid; (4) The content of MDA in leaves of different grape varieties was very low. (5) The tetraploid of POD and CAT in leaves of different grape varieties was higher than that of diploid.
