| Abstract: | The seeds of Tagetes patura were irradiated with ~(60) Co-γ ray of the different dosages and the seed germination rate and seeding growth were observed.The result showed the relation between the germination and the radiant dosage were negative correlation;the relation between the length of bud and the radiant dosage were positive correlation and the relation between the length of root and the radiant dosage were tiny negative correlation.Irradiation could improve the growth of Tagetes patura but it could restrict the rate of seed germination.At the 20 Gy,it was better to improve the germination rate and seeding growth,but it was restrained at the 50 Gy. |

| Keywords: | Tagetes patura Irradiation Germination Length of bud Length of root |
