摘要
以清水处理为对照(CK),研究了低温(温度0～2℃、相对湿度90%～95%)条件下,不同浓度(0.5%、1.0%、2.0%)的氯化钙处理对采后双孢菇(Agaricus bisporus)贮藏生理的影响。结果表明,0.5%浓度的氯化钙处理能够有效的抑制超氧阴离子自由基(O2-)产生速率和脂氧合酶(LOX)的产生、提高过氧化物酶(POD)、超氧化物歧化酶(SOD)、过氧化氢酶(CAT)的活性,减少植物组织中多酚氧化酶(PPO)的产生;1.0%氯化钙处理能够提高POD的活性和降低PPO的活性,但对其他生理指标效果不明显;2.0%氯化钙处理效果不好,不能延缓双孢菇的衰老。综合考虑,0.5%氯化钙溶液处理能够有效的延缓双孢菇的采后衰老,在生产中具有广泛的应用价值。
Under different concentration（water control,0.5%,1.0%,2.0%） of calcium chloride,effects of calcium on storage physiologies of Agaricus bisporus during low temperature circumstances（0～2℃ reserve temperature, 90%～95% relative humidity） were studied. The results indicated that 0.5% of calcium chloride treatment could effectively inhibit the production rate of superoxide anion and lipoxygenase,improve the activities of peroxydase, superoxide dismutase and catalase,and reduce the production of polyphenol. While 1.0% CaCl 2 treatment could improve peroxydase activity and lower the activity of polyphenol,but had no positive effects on other physiologies. 2.0% CaCl 2 treatment had little effects on Agaricus bisporus and couldn’t delay senility of it. To sum up,the treatment of 0.5% CaCl 2 could be used in delaying senility of Agaricus bisporus,and possess of popularization and application value widely.
