摘要
以"红富士"苹果为试材,研究套袋和不套袋对果实品质、耐贮性和农药残留的影响。结果表明:不套袋苹果可溶性固形物含量比套袋苹果提高1%,达到显著程度;果实硬度方面,二者差异不明显;除着色面积、光洁度等外观品质套袋果优于对照外,其它风味、口感等内在品质,以及果实在贮藏期间的硬度、可溶性固形物和失重率等果实耐贮性特征方面,不套袋明显优于套袋;果实的农药残留量没有明显差别,有机磷、有机氯和菊酯类农药均未检出。套袋果实的外观品质好于不套袋;但不套袋果实的内在品质和风味,以及耐贮性等方面显著优于套袋果实;且不套袋果实的农药残留量并没有超过质检标准。
Taking ‘Red Fuji’apple as material,the differences of fruit quality,storability and residues of pesticides were studied by the method of bagged and non-bagged fruits.The results showed that the soluble solids content of non-bagged fruits had increased by 1%compared with that of bagged fruits,this increase was remarkable.There were no significant differences in fruit firmness between bagged and non-bagged fruits.The non-bagged fruits were much better than bagged fruits in fruit quality,including shaded area and flavor.In addition,the storability characteristic,which was measured in firmness,soluble solids content and weight loss rate of non-bagged fruits were all better than that of bagged fruits during storage.The two type fruits had no obvious difference in residues of pesticides.Meanwhile,organophosphates,organ chlorines and parathyroid pesticides were not detected.The non-bagged fruits were much better than bagged fruits in fruit quality and storability except appearance,and two type fruits met the quality standards in residues of pesticides.
