采用电导法和恢复生长法对寒富苹果腋花芽的抗寒机理进行了初步研究。结果表明,低温胁迫下,寒富苹果腋花芽的活力、超氧化物歧化酶(SOD)和过氧化物酶(POD)活性高于同温度处理的顶花芽,游离脯氨酸含量、相对电导率低于同温度处理的顶花芽。 The cold-resistant mechanism of axillary buds in cold-apple was studied by conductivity method and recovery growth method. The results showed that under low temperature stress, the vigor, the activities of superoxide dismutase (SOD) and peroxidase (POD) in axillary buds of Hanfu apple were higher than those of the top flower buds treated with the same temperature, the free proline content, the relative conductivity Below the same temperature treatment top flower buds.
