| 摘 要： | 在芍药"大富贵"品种蕾期,以一定浓度(100mg/L)的维生素C(VC)和不同浓度(60、120、200mg/L)的甘氨酸甜菜碱(GB)混合液对其进行整株喷雾处理,测定了整个花期花瓣中一些与衰老相关的生理生化变化。结果表明:VC与不同浓度的GB混合液处理均提高了花瓣超氧化物歧化酶(SOD)与过氧化物酶(POD)的活力,降低了丙二醛(MDA)含量、超氧阴离子(O2.)产生速率和花瓣浸出液的相对电导率(REC),其中以VC 100mg/L+GB 120mg/L处理效果最好。

| Abstract: | Herbaceous peony ’Dafugui’ were sprayed in the bud period by the solution of a certain concentration(100 mg/L)of vitamin C(VC) and different concentrations(60,120,200 mg/L)of Glycine betaine(GB).Some physiological and biochemical indexes were measured in petals of herbaceous peony in the entire florescence.The results showed that VC and different concentrations of GB could enhance the activity of SOD and POD and decrease MDA content,O·2 production rate and relative electrical conductivity of petals exudate,and VC 100 mg/L+GB 120 mg/L were the best treatments. |
