摘  要:
采用各种活性氧诱发剂(0.5g/L百草枯、10mmol/L H2O2和10mmol/L H2O2+10mmol/L FeSO4.7H2O)及相应的清除剂(20mmol/L没食子酸丙酯、10个单位CAT和70mmol/L DMSO)、外源乙烯(750μl/L乙烯利)、乙烯生成先导物(合成前体,1mmol/L ACC)和乙烯合成抑制剂(10mmol/L AOA)处理香蕉果肉切片。结果表明,在不同成熟度的香蕉果实中,只有存在及乙烯合成不受抑制时,淀粉酶活性才能呈现,果实才能软化、成熟;而及OH.可能在乙烯合成中所起的作用有所不同。

摘  要:
The pulp slices of banana fruit treated with exogenous active oxygen (0.5 g/L paraquat, 10 mmol/L H2O2 and 10 mmol/L H2O2+10 mmol/L FeSO4.7H2O) and corresponding active oxygen scavengers (20 mmol/L propyl gallate, 10 units CAT and 70 mmol/L DMSO), exogenous ethylene (750μl/L ethyephon), the leading product (1 mmol/L ACC) and the inhibitor (10 mmol/L AOA) in ethylene synthesis were investigated. The results showed that in the present of and ethylene, the activity of amylase could exhibit and made the fruit soft and ripe. Otherwise, might have different effect from OH. in synthesis of ethylene.
