不同浓度水杨酸处理对金柑果实贮藏保鲜效果的影响

The Effect of Different Concentratins of Salicylic Acid Treatments on the Storability of Fortunella crassifolia

试验分别在采前1个月和采后对果实进行0.5、1.5、2.5mmol/L水杨酸和清水处理,探讨不同浓度水杨酸处理对金柑果实贮藏性的影响,找出水杨酸处理金柑的最佳浓度和作用时间。结果表明:水杨酸处理可有效地降低金柑果实贮藏过程中的腐烂率和失重率,且采前处理较采后处理效果明显,其中以采前1.5mmol/L水杨酸处理效果最好,各浓度水杨酸处理对果实品质没有负面影响。

In present study,0.5 mmol/L,1.5 mmol/L,2.5 mmol/L SA and water were treated on the tree crown of Fortunella crassifolia 30 d before harvest and postharvest for studying their effects on the storability of fruit. The results showed that, fruit treated via SA treatment had lower disease incidences and weight loss than the control during the storage. While, Pre-harvest SA treatments were better than postharvest treatments. It was also found that the storage of fruit was remarkably improved by the Pre-harvest SA treatment of 1.5 mmol/L. There was no obvious changes on fruit quality caused by SA treatment
