摘要(Abstract)：

【目的】探讨不同贮藏温度对梨新品种‘玉露香’果实保绿效果和品质维持的影响,为生产上针对不同贮藏期限的‘玉露香’保鲜提供技术支撑。【方法】以山西太谷‘玉露香’为材料,通过对果实冰点测定,设定3个不同贮藏温度(分别为-1、0和2℃),于冷藏120和210 d后刚取出时以及相对应的货架10 d时测定生理指标,并调查不同贮藏期果实果心褐变指数和腐烂率,同时对不同温度下贮藏果实进行感官评价。【结果】L值和h值可分别较好地反映‘玉露香’果实油腻化程度和转黄程度,不同温度对‘玉露香’梨保绿效果差异主要体现在贮藏后期(210 d)。贮藏至120 d时,不同贮藏温度下果实腐烂率和果心褐变指数均较低。贮藏至210 d时,-1℃可有效抑制果实油腻化和褪绿转黄的发生进程,并且降低果心褐变指数和腐烂率的发生,而0℃更有利于果实可滴定酸和维生素C含量的维持,-1℃和0℃对果皮L值和h值的影响未达到显著水平。在整个贮藏期,不同贮藏温度贮藏果实的Fv和Fv/Fm在冷库取出时差异不显著,但在(120+10)d时,2℃显著低于-1℃和0℃,在(210+10)d时,-1℃显著高于0℃和2℃。低温(-1℃)能更好地抑制果实贮藏期乙烯释放量和呼吸强度,减缓果皮和果心相对电导率的升高,保持较好的食用品质。【结论】‘玉露香’短期贮藏(不超过90 d)以2℃为宜,贮藏至春节前后,可选择0℃,贮藏至3月份以后以-1~-0.5℃为宜,但贮藏期仍不可超过210 d。
