【摘要】 对5个品系茶树春梢的超氧化物岐化酶(SOD)活性进行了研究,结果表明:春梢中SOD活性安农35号>合肥种>白山大叶种>宁国种>英德大叶种。5个品系茶树春梢SOD同工酶谱带亦不相同。安在35号春梢不同叶位中第2叶SOD活性最强,第3叶,第4叶依次减小,顶芽SOD活性介于第3叶和第4叶之间,丙二醛(MDA)含量与此相反。更多还原

【Abstract】 SOD activity of 5 tea plant cultivars was studied. The result showed that the level of SODactivity in new shoot of Annong 35 cultivar was the highest, followed by the cultivars Hefei, Bais-han, Ningguo, and Yingde. The activity Was different at different leave sites. Those in terminalbud and fourth leave were lower than in second and therd leaves. The content of Malondiadchyde(MDA) had an opposite situation, and isozyme spectra in 5 cultivars were different. The studyprovides a new way to dentify improved variety in early period.更多还原
