摘要
研究了水杨酸对寒富苹果采后品质及乙烯受体基因表达的影响。以未经过处理的苹果果实为对照样品,探讨了不同浓度的水杨酸处理对苹果果实采后贮藏期间乙烯生成量、呼吸速率、硬度、可溶性固形物含量和乙烯受体基因MdETR1和MdERS1表达的影响。实验结果表明,与对照组相比,不同浓度的水杨酸处理能够有效抑制寒富苹果果实的乙烯生成量和呼吸速率,提高了苹果果实的硬度,延缓了苹果果实可溶性固形物的上升速度,抑制了苹果果实乙烯受体基因的表达水平。其中,浓度为1.0mmol/L水杨酸对提高苹果果实品质的效果更加显著。由此可见,水杨酸处理可以提高苹果果实的贮藏期商品品质,并延缓了苹果果实的后熟与衰老进程,为水杨酸在果蔬采后贮藏保鲜的应用提供理论依据。
Here,by study with effectiveness of treatment with SA on postharvest quality and ethylene receptor gene expression in apple fruit,the effectiveness of treatment with different concentrations of SA on ethylene production,respiratory rate,firmness,soluble solid content and ethylene receptor gene expression of postharvest apples compared to untreated samples during storage were investigated.The results showed that SA can effectively restrain the ethylene production and respiratory rate,improve the firmness,decay the increasing of soluble solid content,and suppress the ethylene receptor gene expression level.However,1.0 mmol/L SA showed better effectiveness than other treatments on improving quality of apples.Therefore,it is clear that SA can improve the commodity quality and delay the process of ripening and senescence of stored apple fruit,which provided a theoretical basis for the application of SA in the storage and preservation of fruits and vegetables.
