氯苯胺灵对马铃薯亚常温发芽及品质的影响

为明确氯苯胺灵[isopropyl N-(3-chlorophenyl)carbamate,CIPC]处理对马铃薯块茎12℃亚常温贮藏期间发芽及品质的影响,以费乌瑞它马铃薯为试材,研究12℃亚常温下,质量浓度为0.3 g/kg CIPC处理后块茎贮藏150 d的发芽情况、营养品质及动态残留,并与4℃低温和12℃亚常温贮藏效果进行对比。结果表明,与4℃低温对照相比,12℃+0.3 g/kg CIPC处理减缓了块茎内淀粉向还原糖的转化,同时保持了可溶性蛋白含量;与12℃亚常温对照相比,12℃+0.3 g/kg CIPC处理显著抑制了块茎呼吸强度、降低发芽和鲜重损失,且对块茎营养品质有积极的保持作用;短期贮藏30 d后薯皮和薯肉中CIPC残留量均低于残留限量标准(30 mg/kg)。因此,0.3 g/kg CIPC可作为12℃亚常温下马铃薯长期贮藏高效的抑芽剂使用。
