以不同成熟度的赛买提杏(Armeniaca vulgaris cv．‘Saimaiti’)为材料,研究 MeJA 对其保护酶的影响.用0 mol/L(CK)、1×10－6 mol/L MeJA处理绿熟期、完熟期的赛买提杏,在常温(18~25℃)贮藏6 d,研究货架期间不同成熟度的赛买提杏 MDA含量变化及 SOD、POD、CAT的活性变化.结果表明,1×10－6 mol/L MeJA能有效抑制绿熟和完熟期赛买提杏中 MDA含量的增长；延缓绿熟期、完熟期赛买提杏中 SOD、POD和 CAT活性的下降. MeJ A能提高保护酶的活性,抑制货架期不同成熟度赛买提杏的膜脂过氧化程度.

With different maturity of Armeniaca vulgaris cv.‘Saimaiti’as the experimental material,the effect of MeJA on protective enzymes was studied.The 0 mol/L(CK),1×10-6 mol/L MeJA were used to treat the mature and green ripe stage Armeniaca vulgaris cv.‘Saimaiti’respectively,storaged at room temperature (18-25 ℃)for 6 days to study MDA contant and SOD,POD and CAT activity changes in Armeniaca vulgaris cv.‘Saimaiti’.Results showed that 1 ×10-6 mol/L MeJA treatment,both green and mature apricot,MDA content were decreased;the decrase rate of SOD,CAT and POD activity were de-layed.MeJA can improve the activity of protective enzymes,inhibiting membrane-lipid peroxidation of apri-cot in shelf-life.
