摘　　要：本研究旨在探究茉莉酸甲酯结合氯化钙对红托竹荪贮藏品质的影响。本实验以红托竹荪为试材,研究不同处理(对照组为采前喷施蒸馏水(CK);采前喷施3%氯化钙(S1);采前喷施0.3 mmol/L茉莉酸甲酯(S2);采前喷施0.3 mmol/L茉莉酸甲酯结合3%氯化钙(S3))在温度(1±0.5)℃条件下对红托竹荪贮藏品质的影响。结果表明,与CK组比较,不同处理组均能够抑制红托竹荪失重率和呼吸强度的上升,降低红托竹荪剪切力和丙二醛含量,保持红托竹荪游离氨基酸含量、蛋白质含量、多糖含量和黄酮含量,维持红托竹荪SOD活性、CAT活性和POD活性。在贮藏期12 d时,CK组、S1组、S2组和S3组的红托竹荪腐烂率分别为32.56%、28.32%、19.85%、14.64%,失重率分别为5.62%、3.89%、2.89%、2.21%。综合比较,茉莉酸甲酯结合氯化钙能够显著推迟红托竹荪的劣变进程,延缓红托竹荪贮藏品质的下降。因此,采前用茉莉酸甲酯结合氯化钙处理红托竹荪最好,能够更好地保持红托竹荪的贮藏效果。本研究可为红托竹荪的保鲜研究提供理论参考和技术支撑。The aim of this study was to investigate the effects of combined treatment of methyl jasmonate and calcium chloride on storage quality of Dictyophora rubrovalvata.The Dictyophora rubrovalvata was used as the experimental material in this experiment,and the effects of different dealing methods(preharvest distilled water spray treatments mark CK,preharvest 3%calcium chloride spray(S1),preharvest 0.3 mmol/L methyl jasmonate spray(S2),preharvest 0.3 mmol/L methyl jasmonate+3%calcium chloride spray(S3))on the storage quality of Dictyophora rubrovalvata at(1±0.5)℃were studied.The results showed that compared with CK group,the different treatment groups could inhibit the increase of weight loss rate and respiratory intensity,reduce the Dictyophora rubrovalvata shearing force,malondialdehyde content,maintain the free amino acid content,protein content,polysaccharide content and flavone content,and maintain the SOD,CAT and POD activity of the Dictyophora rubrovalvata.At 12 d of storage,the decay rate of Dictyophora rubrovalvata in CK,S1,S2 and S3 groups was 32.56%,28.32%,19.85%and 14.64%,and the weight loss rate was 5.62%,3.89%,2.89%and 2.21%.In general,methyl jasmonate combined with calcium chloride could significantly delay the deterioration process of Dictyophora rubrovalvata and the decline of its storage quality.Therefore the combination of spraying methyl jasmonate combined with calcium chloride before picking had the best fresh-keeping effect,which could maintain the storage effect of Dictyophora rubrovalvata.This study can provide theoretical reference and technical support for the preservation of Dictyophora rubrovalvata.
