摘要
以绿叶蔬菜芥兰(Brassica alboglabra Bailey)为试材,在确定适宜熏蒸时间的基础上,观测了不同浓度NO(60、100μl/L)气体对芥兰采后失重、开花率、黄化率及抗氧化酶系的影响。结果表明:利用外源NO处理芥兰的适宜处理时间是30min,芥兰的存在能够控制贮藏环境中NO氧化产物NO2的积累。外源NO处理对芥兰采后失重率无显著影响,但是能够显著抑制芥兰采后开花及叶片黄化。外源NO处理能够抑制芥兰采后SOD、CAT活性的下降,并能控制芥兰组织中MDA含量的上升。
In order to determine the proper fumigation time of nitric oxide (NO), the change tendencies of NO concentration from 60 μl/L and 100μl/L were investigated in the presence of Brassica alboglabra Bailey. Furthermore, the effects of NO concentrations of 60 μl/L and 100 μl/L on postharvest weight loss, flowering ratio, yellowing ratio of leaves and anti-oxidation enzymes were also investigated. The results showed that the proper fumigation time of NO is 30 minutes. The presence of Brassica alboglabra Bailey ca...
