Abstract:
The changes of some physiological indexes of antioxidation metabolism were studied in floral buds of ‘Zhonghuashoutao’ peach during the dormancy for two successive years.The results showed that there were some differences in dormancy progression,soluble protein content,total amino acids content,POD activity,H2O2 content,and AsA content in floral buds.The time of endodormancy maintenance of floral buds in 2013—2014 was longer than that of floral buds in 2014—2015.The content of soluble protein gradually decreased,however,the total amino acids content gradually increased during endodormancy and dormancy release.POD activity and H2O2 content occurred on the same change.It appeared the trend of variation ‘up-down-up-down’.But there was difference in the occurring date of maximum and minimum values of AsA content between two years.
