山野菜在采集离体后的老化速度很快,造成的损耗严重.为解决这一问题需要探讨采集后发生的生理生化变化,文献上没有查到山野菜在这方面的直接文献.在其它植物中对机械伤害(如切割、触摸、虫咬等)和化学损害(如真菌浸染、大气污染物影响等),植物都能产生一系列的变化.如呼吸作用加速、呼吸途径变化;近年来对伤害的刺激较多研究的是信号传递,如化学信号和电信号.更多的集中在乙烯的诱导形成,并对伤害诱导的基因表达、乙烯生物合成的前体 ACC 合成酶和氧化酶得到进一步证实.还 In order to solve this problem, we need to discuss the physiological and biochemical changes after the collection, and there is no direct literature about the wild plants in this field.In other plants In the mechanical damage (such as cutting, touching, insect bites, etc.) and chemical damage (such as fungal infection, the impact of air pollutants, etc.), plants can produce a series of changes, such as respiratory acceleration, respiratory pathways change in recent years Much more damage is stimulated by signaling, such as chemical and electrical signals. More focused on the induction of ethylene formation and on injury-induced gene expression, ethylene biosynthesis precursors to ACC synthase and oxidase are further Confirmed. Also
