    摘要:

    為研究氣調(diào)對(duì)蕨菜貯藏期間保鮮效果的影響,，設(shè)置不同CO2和O2的體積分?jǐn)?shù),，對(duì)蕨菜采 后SOD活性、POD活性,、呼吸強(qiáng)度,、乙烯釋放量、蕨菜干鮮重以及丙二醛,、葉綠素,、可溶性糖 、VC含 量進(jìn)行了研究,。結(jié)果表明：適宜的CO2和O2組合有利于采后蕨菜維持較高的SOD和POD活 性,，減少了MDA的積累，維持恰當(dāng)?shù)暮粑鼜?qiáng)度和乙烯釋放速率,，減少蕨菜干鮮重的損失 ,，利于蕨菜采后葉綠素、可溶性糖,、VC的保存,。試驗(yàn)得出了最好的氣體組合,即CO2和O 2體積分?jǐn)?shù)為2%和6%，其次為6%和10%,，這些組合能很好地保持蕨菜貯藏中的品質(zhì),，可使蕨 菜保鮮期達(dá)15d以上。

    Abstract:

    In order to research the effects of modified atmosphere on the preservation of Pteridium aquilinum during storage period, the SOD and POD activity, respir ation rat e and ethylene release,，fresh and dry weight, MDA, chlorophyll, soluble sugar an d VC content were studied by setting different CO2 and O2 proportion. Result s showed that, proper CO2 and O2 proportion can maintain the higher SOD and POD activity, decrease the content of MDA, keep the respiration rate and ethylen e release appropriately, reduce the loss of dry and fresh weight, eventually ava il to the preservation of chlorophyll, soluble sugar and VC content. In this exp eriment, the optimal CO2 and O2 proportion is 2% and 6%, second is 6% and 10 %. The combination could commendably retain the quality of Pteridium aquilin um up to above 15d.
