摘      要：To elucidate the potential and sensitivity of cirradiation in Pongamia pinnata,the present study has been done by irradiating the air-dried seeds to differentγ-irradiation doses(100 Gy,200 Gy,400 Gy and 600 Gy),using 60Co *** increase(p≤0.05)in the germination,growth,and vigor was recorded under the100 Gy treatment than the control *** chlorophylla and total chlorophyll content(mgg-1 FW)in the leaves of *** showed a significant decrease under the higher irradiation treatments(200 Gy,400 Gy and 600 Gy).In contrast,chlorophyllb showed a radio-resistance up to 200 Gy dose,and above which its concentration declined significantly(p≤0.05).Photosynthetic rate,stomatal conductance,intercellular CO2 concentration,and transpiration rate were stimulated by 100 Gy irradiation treatment and the higher doses inhibited these *** activity in the leaves of *** tended to increase after irradiation in a dose-dependent *** the plants under different treatments ofγ-irradiation showed stimulation in production of proline,flavonoid,and phenolic content in comparision to the *** findings of the present study showed thatγ-irradiation treatment stimulates the secondary metabolite production(proline,flavonoid and phenolic)and favours faster growth of ***.
