摘要:
以“宁杞1号”为材料，以硝普钠（SNP)为一氧化氮（NO）供体，研究了不同浓度NO对枸杞果实采后生理效应的影响。结果表明：外源NO处理，能有效减少果实失重率和果实腐烂指数，推迟果实可溶性固形物含量下降，抑制果实乙烯的产生和呼吸速率，能增强果实超氧化物歧化酶（SOD）、过氧化氢酶（CAT）、过氧化物酶（POD）活性，降低丙二醛(MDA)含量，且以0.50 mmol?L-1 SNP溶液浸泡处理效果最好。试验表明，适宜浓度的SNP处理可以提高枸杞果实采后保鲜效果。
Abstract:
Taking Lycium barbarum L.‘Ningqi No.1’ as material,SNP as donor of NO,the physiological effects of nitric oxide(NO)on postharvest fresh fruits of Lycium barbarum L.were studied.The results showed that exogenous NO could depress the weight loss rate and decay rate,delay the decrease of content of soluble solids,inhibit ethylene production rate and respiration rate,increase the activities of SOD,CAT and POD,reduce MDA content.The 0.50 mmol?L-1 SNP treatment was the best.The experiment indicated that the exogenous nitric oxide could improve preservation effect of Lycium barbarum L.after harvest.
