Abstract:
The experiment was carried out to investigate the mutagenic effects of gamma radiation on chlorophyll concentration in the J. auriculatum physiological stages of flowering. The LD₅₀ (50 percent lethality) was attained at 20 Gy. Three doasges 15, 20 and 25 Gy of gamma rays were subjected. The cuttings were planted to raise the M₁V₁ generation. The M₁V₁ generation cuttings were collected and planted in the next season to raise the M₁V₂ generation. Leaf chlorophyll content was measured for M₁V₁ and M₁V₂ generation plants. Flowering stage mean ranged from 54.52 (control) and 55.25 (best treatment). The decrease in chlorophyll is observed when increase gamma irradiation in both M₁V₁ and M₁V₂.
