摘要: 研究了不同浓度的外源乙醇(1、2和3ml/kg)采后处理对食荚豌豆低温贮藏期间主要生理指标、腐烂和品质的影响。结果表明,lml/kg的外源乙醇可有效抑制食荚豌豆贮藏期间的呼吸强度、乙烯释放和蒸腾失水,延缓了豆荚中叶绿素含量的下降及纤维素和木质素含量的上升,降低豆荚贮藏中腐烂的发生,从而较好地保持豆荚的食用品质,延长贮藏期。2和3ml/kg乙醇处理促进了食荚豌豆的衰老进程和腐烂发生,这可能与高浓度乙醇对豆荚产生伤害有关。

Abstract: Edible podded peas(Pisum. sativum L. var. macrocarpon Ser.)were tr ea ted with different concentrations of ethanol vapor(1, 2 and 3ml/kg)at 20℃ for 24h before storage at 1℃for 35days. Treatment with 1ml/kg ethanol could signifi cantly inhibit the respiratory rate, ethylene production and weight loss, decre a se the chlorophyll content increase the crude fibre and lignin contents and in hi bit decay incidence, thereby maintaining better quality and prolonging the st ora ge life. Treatments with 2ml/kg and 3ml/kg ethanol promoted the senescence p roce ss, as manifested by higher respiratory rate and ethylene production and in creas ed decay incidence. It clearly showed that high concentrations of ethanol caused injury to edible podded pear.
