摘要: 以‘秦光2 号’油桃和‘秦王’桃为试材, 在0 ℃和5 ℃两种贮藏温度条件下研究了1-甲基环丙烯(1-MCP) 对果实呼吸速率、乙烯释放速率、硬度、可滴定酸含量、可溶性固形物含量及果肉褐变的影响。结果表明, 0 ℃的贮藏温度能显著降低秦光2号油桃和秦王桃的呼吸速率和乙烯释放速率, 减缓果实软化。1μL·L -1的1-MCP 处理能降低果实的呼吸速率和乙烯释放速率, 抑制果实软化, 减少果肉褐变,但对可滴定酸和可溶性固形物含量无明显影响。

Abstract: Effects of 1-methylcyclopropene (1-MCP) and storage temperatures on respiratory rate and ethylene production rate were investigated in relation to flesh firmness , titratable acid , total soluble solids and internal browing of ‘Qinguang 2’nectarine and ‘Qinwang’peach fruits during storage at 0 ℃and 5 ℃. Fruit stored at 0 ℃had more reduced rates of respiration and ethylene production , firmer flesh and less internal browing compared with those at 5 ℃. Application of 1μL·L-1 1-MCP inhibited the rates of both respiration and ethylene production, delayed fruit soffening and reduced internal browing , but had no obvious effects on contents of titratable acid and
total soluble solids. The potential to use 1-MCP for storage and transport of nectarine and peach can be expected.
