INFLUENCE OF FAST NEUTRON IRRADIATION AND SODIUM AZIDE ON SESAME.
Abstract:
This research aimed to investigate the impacts of Fast Neutron Irradiation (FNI) and Sodium Azide (SA) on three Sesame (Sesamum indicum) varieties: Kenana-4, Ex-Sudan, and E-8. Each variety had 300 seeds exposed to FNI from an Americium-Beryllium source with a flux of 1.5×10^4 n.cm^-2s^-1 at doses of 0, 4, 8, 12, and 16µSv. Additionally, 300 seeds of each variety were treated with Sodium Azide at five different concentrations: 0.00%, 0.02%, 0.04%, 0.06%, and 0.08%. The irradiated, chemically treated, and control seeds were cultivated to maturity, and various morphological and yield parameters were measured, including survival rate, flowering, and oil content.
The results revealed that the 12µSv dose led to significantly higher values (p<0.05) for plant height, number of leaves, length of petiole, and number of seeds. Survival percentages were highest at 0µSv (60% for Ex-Sudan and E-8, and 53% for Kenana-4). In terms of oil content, 16µSv and 8µSv consistently produced the highest percentages across all three varieties. Regarding flowering percentage, Kenana-4 showed higher values at 8µSv and 12µSv (75% each) compared to the control. However, Ex-Sudan and E-8 performed better at 4µSv (78.1% and 46.8%, respectively) compared to the control.
For Sodium Azide, the results indicated that the 0.02% concentration led to significantly higher values (p<0.05) for plant height, number of leaves, length of petiole, leaf surface area, and capsule weight. Survival percentages were highest at 0.02% for Ex-Sudan, 0.08% for Kenana-4, and 0.04% for E-8 (80%, 93%, and 94%, respectively). In terms of oil content, Kenana-4 and E-8 showed higher values at 0.08% (37.7% and 28.6%, respectively), while Ex-Sudan exhibited its highest value (30%) at 0.00%. Regarding flowering percentage, Ex-Sudan and E-8 demonstrated higher values at 0.02% (75% and 53.1%, respectively), while Kenana-4 achieved its highest value (78%) at 0.04%.
In conclusion, Fast Neutron Irradiation and Sodium Azide have the potential to induce genetic variability in sesame. Specifically, concentrations of 0.02% to 0.04% Sodium Azide and a 12µSv dose of Fast Neutron Irradiation show promise for creating variability that can be utilized for sesame improvement.
