Abstract:
Taking blackberry cultivar(Rubus spp.cv‘Arapaho’) as material,from the stage of three days after flower (DAF) to the maturation process,fruit antioxidant system of ‘Arapaho’ was investigated.The results showed that superoxide dismutase (SOD) and peroxydase (POD) activity first increased and then decreased,catalase (CAT) activity decreased gradually during the fruit development and ripening process;antiscorbic acid (AsA) and free proline (Pro) content decreased during the fruit ripening process,glutathione (GSH) content and the generation of O2 first increased and then decreased,MDA content showed no significant difference in the process of fruit development.The combination of antioxidases SOD,POD,CAT and antioxidant materials AsA,GSH,Pro played an important role to keep the balance of generating and scavenging of active oxygen in the process of fruit development,and ensure fruit to develop and mature.
