THE INFLUENCE `OF CAFFEINE AND EDTA POST TREATMENT ON BIOLOGICAL EFFECT OF SOYBEAN AND RAPE SEEDLING |
| |
| Abstract: | The biological effect of Caffeine and EDTA post treatment on soybean and rape seedling was studied. The results showed that the seed germinating rates of the two crops were obviously affected by radiation, caffeine and EDTA post treatment. The seedling growth of the two crops were promoted by lower radiation dose (soybean < 100Gy, rape<600Gy). The root length, seedling height, dry weight and IAA content of the two crops significantly decreased with the increase of radiation dose; with caffeine and EDTA post treatment, the root length, seedling height and dry weight were lower, but IAA content were higher than that with H 2O treatment. The accumulative effects on the seedling root length, seedling height and dry weight of the two plants were observed with the post treatment with combining of caffeine and EDTA. |
