褪黑素对青椒低温贮藏品质及能量代谢影响
Effects of Melatonin on Storage Quality and Energy Metabolism of Green Pepper(Capsicum frutescens L.)During Low Temperature Storage
摘要
Abstract
In order to study the effect of melatonin on the storage quality and energy metabolism of postharvest green pep-per(Capsicum frutescens L.).The green pepper was used as the experiment material in this experiment with different concentrations(100,200 and 300 μmol/L)at low temperature(9℃).To investigate the effects of melatonin treatment on the storage quality and energy metabolism of green pepper fruits.The results showed that melatonin treatment could effe-ctively reduce decay rate and slow down the decline of fruit hardness of green pepper.In particular,the treatment effect of 200 μmol/L melatonin was the best.In addition,melatonin could delay the decline of capsaicin and chlorophyll content,mai-ntained a lower MDA content,inhibited the degradation of ATP,ADP and AXP,promoted the accumulation of AMP con-tent,and maintained a higher energy charge level in green pepper.Melatonin could also maintain high SDH,CCO,H+-ATPase and Ca2+-ATPase activity in green pepper.Correlation analysis showed that the activities of ATP,ADP,AXP,energy charge,H+-ATPase and Ca2+-ATPase in green pepper were significantly negatively correlated with the decay rate(P<0.05),and were significantly positively correlated with the contents of capsaicin and chlorophyll(P<0.05).Moreover,the activities of ATP,ADP,AMP,AXP,energy charge,H+-ATPase and Ca2+-ATPase in green pepper were significantly positively correlated with each other(P<0.05),indicating that melatonin treatment could explain that the quality of post-harvest green pepper was closely related to energy level during storage.The results of this study can provide technical refe-rence for the application of melatonin in controlling the storage quality of postharvest green pepper.关键词
