Abstract
The present investigation aimed at estimating the influence of gamma rays on germination and growth parameters of groundnut revealed suppressive effect compared to non irradiated seed. Groundnut seed (Narayani) were exposed to gamma rays ranging from 0.70 kGy to 2.30 kGy using CO gamma radiation (GC 5000) facility at Quality Control Laboratory, Acharya N.G Ranga Agricultural University, Rajendranagar, Hyderabad during 2010-2011. To find out LD dose for the seed and further investigate the influence on germination and seedling parameters. The experimental results revealed that the percentage of germination had decreased after irradiation and the effect become stronger with increase of gamma dose. Parameters such as germination percentage, speed of germination, mean daily germination, peak value and germination value had significantly decreased with increased irradiation doses. Similarly seedling parameters viz., Root length, Shoot length, Vigour index and Root/Shoot length ratio expressed higher reduction at higher doses as compared to non irradiated control. The study clearly indicated increase in the deleterious effects of gamma irradiation at regular intervals, with attainment ofLD at a dose of 1.50 kGy.
