中文摘要: 为明确采后6-苄氨基嘌呤(6-benzaminopurine,6-BA)处理对梨货架期的保鲜效果,以‘苏翠1 号’梨为试材,以清水处理为对照,探究0.1 g/L 6-BA 浸泡处理10 min 对‘苏翠1 号’梨常温[(24±2)℃]货架期品质的影响。结果表明,与对照组相比,6-BA 处理有效地延缓货架期梨果皮叶绿素含量、果肉硬度、果肉可溶性糖含量、可滴定酸含量和维生素C 含量等品质指标的下降,还可以抑制果实失重率的增加。6-BA 处理可以有效地降低‘苏翠1 号’梨在整个货架期的呼吸速率和乙烯释放速率,使梨果实保持相对较高的超氧化物歧化酶、过氧化物酶和过氧化氢酶等抗氧化酶活性和较低的丙二醛含量,这可能是6-BA 处理减轻梨果实细胞膜氧化性损伤、延缓梨品质下降和衰老发生的原因。该研究证明6-BA 处理对‘苏翠1 号’梨具有明显的保鲜效果,可有效地延缓货架期品质的下降。
Abstract:In order to determine the effect of postharvest 6-benzaminopurine(6-BA)treatment on the preservation of pears during shelf-life storage,the effect of 0.1 g/L 6-BA immersion treatment for 10 min on the quality of‘Sucui 1’pears during shelf life at room temperature [(24±2)℃] was investigated,and the water treatment was set as the control group. The results showed that compared with the control group,6-BA treatment could effectively delay the decline of chlorophyll content of peel,flesh hardness,soluble sugar content,titrable acid content,and vitamin C content during shelf life and inhibit the increase in weight loss.6-BA treatment could effectively reduce the respiration rate and ethylene release rate of‘Sucui 1’pear during shelf life and maintain relatively high antioxidant enzyme activities such as superoxide dismutase,peroxidase,and catalase and lower malondialdehyde content of the pear. These may be the possible reasons that 6-BA treatment could reduce the oxidative damage of cell membranes and delay the senescence and degeneration of pears during their shelf life. This research indicated that 6-BA treatment had an obvious fresh-keeping effect on‘Sucui 1’pears and could effectively delay the quality decline during shelf life.
