Effect of ~(60)Co-γ ray Irradiation on Germination Rate of Seed and Seedling Growth of Celosia cristata
QIANG Ji-ye et al ( Department of Physics, Lishui University, Lishui,Zhejiang 323000)
The Celosia cristata was irradiated wigh 60Co-γ ray and its germination rate and seedling growth were observed. The results showed that there was a positive correlation between irradiation desage and germination rato, but there was a negative relationship between the length of roots, the height of seeding and the irradiation dosage . And the results also indicated that though it could improve the germination rate, it restricted the seedling growth.
