摘要
以哈密瓜品种"西州密25号"为试材,用浓度为0.1、0.3、0.5g·L^(-1)水杨酸(SA)处理后,分别放置于0、5、20℃贮藏,测定不同浓度水杨酸处理后哈密瓜果实可溶性固形物(TSS)含量、可滴定酸(TA)含量和超氧化物歧化酶(SOD)活性的变化。结果表明:与对照(清水)相比,在5℃贮藏条件下,经0.3g·L^(-1)水杨酸处理后,可以显著地保持贮藏期间哈密瓜果实可溶性固形物和可滴定酸含量,抑制SOD活性下降,延迟哈密瓜果实后熟,较好地保持了哈密瓜贮藏期间果实的品质。
Taking Hami melon species ‘Xizhoumi-25'as test material,concentration of 0.1,0.3,0.5g·L^(-1)salicylic acid(SA)were treated,then were preserved at 0,5and 20 ℃.The contents of soluble solids(TSS),titratable acid(TA),and superoxide dismutase(SOD)activity of ‘Xizhoumi-25'were determined with the different concentrations of salicylic acid treatment.The results showed that compared with the control(water),under the condition of 5℃,the treatment of 0.3g·L^(-1) salicylic acid could significantly maintain the contents of TSS,TA and SOD activity of‘Xizhoumi-25'fruit ripening was delayed.‘Xizhoumi-25'fruit quality was better kept during the storage.
