采后UV-C处理对葡萄抗病性和品质的影响
Effects on Disease Resistance and Quality in Harvested Grape by UV-C Treatment
摘要
Abstract
[ Objectives ] Influences of low energy short wave ultraviolet (UV-C) to decay of grape and action mechanism were studied for providing scientific basis of UV-C application in fresh-keeping. [ Method] Grape fruits were exposed to UV-C irradiation energy levels of 0'0.5、1.0、1.5、2.0 kJ/m2 and then stored for 12 weeks at 0 ± I ℃, 90% RH. Decay index, total phenols ( TP), total flavonoids ( TF), enzymatic activity of phenylalanine ammonia-lyase (PAL), polyphenoloxidase (PPO), chitinase and β-1,3-Glucanase were measured thereafter every 2 days. [ Result] UV-C treatment maintained lower decay percentage and increased shelf life of fruit. These benefits correlated positively with higher levels of TP, TF, PAL, PPO, chitinase and β-1,3-Glucanase. [ Conclusion ] These results suggested that the inhibition of postharvest grape fruit decay by UV-C was related to the induction of defensive enzyme activities and accumulation of phenolic and flavonoids compounds关键词
