摘要
对柠条苗期中7个生长阶段、3种器官中的PAL粗酶进行提取,并测定了相关样品的活性和比活性。结果表明:在柠条干种子中PAL活性较低;浸泡至硬化期,柠条根、茎、叶中的PAL活性和比活性均呈抛物线变化;柠条根中PAL活性和比活性以真叶期最高,其茎和叶中PAL活性和比活性以速生期最高。
The activity and specific activity of phenylalanine ammonia-lyase （ PAL, EC 4.3.1.5 ） were determined periodically during the 7 seedling growth stages of leaf, stem and root of Caragana korshinkii Kom. The results were as follows ： the PAL activity of its dry seed was lower; the PAL activity and specific activity of leaf, stem and root of C. korshinkii Kom from seed at hardening stage displayed parabola type; the PAL activity and specific activity of its root were the highest at the real leaf stage; the PAL activity and specific activity of its leaf and stem were the highest at rapid growth stage.
