摘要
研究新型抑芽剂3-癸烯-2-酮对马铃薯的抑芽保鲜效果,为马铃薯抑芽保鲜方面的应用提供了参考依据.以马铃薯品种青薯9号为试验材料,分别采用0.05、0.10、0.15、0.20、0.30 mL/kg的3-癸烯-2-酮对马铃薯进行抑芽熏蒸处理,考察马铃薯的抑芽效果以确定适宜剂量,并研究适宜剂量下的3-癸烯-2-酮对马铃薯失重率、呼吸强度、抗氧化酶活性和膜脂过氧化等生理指标的影响.结果表明,3-癸烯-2-酮的适宜剂量为0.15 mL/kg,可显著降低贮藏期间的失重率、呼吸强度,延缓了膜脂过氧化程度,并提高了马铃薯的抗氧化酶SOD和CAT活性.
Abstract
This study investigates the inhibitory effect of the novel sprout inhibitor 3-decene-2-one on potato sprouting,providing a reference for its application in potato preservation.Using the potato variety Qingshu 9 as the test material,potatoes were subjected to fumigation treatments with 3-decene-2-one at doses of 0.05,0.10,0.15,0.20,and 0.30 mL/kg to assess the sprouting inhibition and determine the appropriate dose.Effects of the optimal dose of 3-decene-2-one on physiological indicators,including weight loss rate,respiration intensity,antioxidant enzyme activity,and membrane lipid peroxidation in potatoes,were studied.The results indicated that the suitable dose of 3-decene-2-one is 0.15 mL/kg,which significantly reduces weight loss,respiration intensity,and membrane lipid peroxidation during storage,while increasing antioxidant enzyme activity of SOD and CAT in potatoes.
