摘　　要：研究了亚精胺与乙烯对赛买提杏货架期生理生化的互作效应。将0.1 mmol/L亚精胺(S)和100μL/L乙烯利(C)溶液采用不同处理顺序对采后绿熟期新疆赛买提杏进行实验,在常温条件下模拟货架期,每天取样分析不同处理对乙烯释放量、硬度、叶绿素、TSS、TA和抗坏血酸等各指标的影响,探讨货架期亚精胺与乙烯对赛买提杏生理生化的交互作用。结果表明:先亚精胺后乙烯利处理可延缓果实硬度下降的速度,降低乙烯释放量并推迟乙烯高峰,维持杏果实的品质;混合溶液处理与先亚精胺处理结果相似,但可滴定酸含量下降较快,先乙烯利后亚精胺处理能改善果实风味,但加速了果实软化衰老进程。The effect of the spermidine and ethylene on the quality and maturity of ＂Samaiti＂ apricot was studied in this paper. 0.1 mmol/L spermidine and 100 μL/L ethephon solution using different sequence experiment of postharvest green ripe stage in Xinjiang ＂Saimaiti＂ apricot, simulated shelf life under the condition of normal temperature, daily sampling analysis indexes of different treatments on ethylene production, firmness, chlorophyll content, TSS, TA and ascorbic acid. Physiological and biochemical interaction was studied. Results show that： Spermidine treatment then ethephon treatment can delay the decrease speed of fruit firmness and reduce ethylene release and delayed the peak of ethylene, to maintain quality of apricot fruit. Mixed solution treatment results were similar, but the fast decrease of the titratable acid content. Ethephon treatment then spermiatment can improve the flavor of fruit, but accelerated the fruit softening and senescence.
