| Abstract: | Different dose of nitrogen ion were injected into seeds of the twin-embryo rice seeds 09-02-01 and the corresponding autotetraploid 09-04-01.The electrolyte permeability and the seedling growth conditions were investigated,and the effects on peroxidase(POD) activity,superoxide dismutase(SOD) activity,catalase(CAT) activity was researched.The results showed that the average increase in electrolyte leakage rate the dose of 09-04-01 was lower than that for 09-02-01 after ion implantation.The 09-02-01 seedling ... |
| Keywords: | twin-embryo seedlings rice nitrogen ion implantation enzyme activity |
