杂交棉冀棉18号一代、二代的SOD和POD活性及生理生化机制研究

Study on the SOD and POD Activity and Physiological Biochemical Mechanism in F_1 and F_2 of Cotton Hybrid Jimian No.18

对冀棉18号F1和F2花铃期的SOD和POD活性及生理生化机制进行了研究。结果表明,冀棉18号F1和F2花铃期的同化量明显高于对照种中棉12,并且光合产物主要运输到蕾铃等生殖器官上;F1和F2的SOD活性差异不明显,并与亲本和对照相近;F1的POD活性略高于F2,二者均明显高于对照。

This paper examined the SOD and POD activity and physiological and biochemical mechanism in F1 and F2 of jimian No.18.The result showed that the assimilation rates of the F1 and F2 generations were significantly higher than that of Zhongmian 12,and the major photosynthesis products were allocated to the reproduction organs.SOD activity in F1 and F2 of Jianmian No.18 showed similar,which was also close to that of their parents and the ck.However,POD activity in F1 had higher than in F2,both F1 and F2 had significantly higher than the ck.
