[Study on the physiological and biochemical characteristics of different types of leaves of Aquilaria sinensis].
摘要
OBJECTIVE: To study the physiological and biochemical characteristics of different types of leaves of Aquilaria sinensis. METHODS: Six types of leaves' physiological and biochemical indexes were studied and analysed, these indicators included: malondialdehyde (MDA), soluble sugar content, soluble protein content, peroxidase activity (POD), catalase activity (CAT) and superoxide dismutase activity (SOD). RESULTS: POD, CAT, SOD had no significant difference; POD, CAT, and SOD had a coordinating role on cleaning-up oxidation products MDA; The soluble protein contents of different types of leaves was negative corelatad with the centent of MDA; The contents of soluble sugar among them were signifiant different. CONCLUSION: Growth activity sequence of different types of Aquilaria sinensis is as follows: lobular type > large-leaved type, transitional leaf type > elliptical leaf type.
