Abstract
In order to research the relationship between the related enzyme activities in leaves of the Anli anti-browning strain and the anti-browning phenomenon of it's fruits,and provide evidence for the early anti-browning selection of Anli strain varieties,the activities of POD,CAT,PPO and SOD were studied using the leaves of anti-browning Anli strain,and two non anti-browning varieties,Anli pear Yanan-1 and Yanan-2.The results showed that the POD and CAT activities were(48.36±3.27) U/(g·min) and(122.65±8.34) U/(g·min) in anti-browning Anli strain leaves,significantly higher than the two anti-browning varieties.The activities of POD,CAT and PPO in the three Anli pear activities(strains) were(from large to small): anti-browning,Yanan-1,Yanan-2.SOD activity was not related with the browning degree of fruits.
