Vegetative and reproductive response of sorghum to gamma-rays treatment

, : Vegetative and reproductive response of sorghum to gamma-rays treatment. Annals of Agricultural Science, Ain Shams University 30(1): 195-206

In 1982-3 seeds of sorghum Giza 3 and Giza 15 were exposed to 0, 2.5, 5, 10, 20, 40, 60, 80 or 100 kr gamma rays before sowing in the field. The 20 and 40 kr doses increased tiller number in both cv., while plant height and the number of internodes/plant decreased. Plant height at 40 kr was reduced by 16.2 and 17.3% (1982) and 0.05 and 10.0% (1983) for Giza 3 and Giza 15, resp.

The maximum stimulatory effect was observed at the dose of 10 Krd of X-rays and 5 Krd of gamma-rays. However, percentage surviva...
