GERMINACIÓN DE SEMILLAS DEL PASTO SABOYA (Panicum maximum), EXPUESTOS A DIFERENTES NIVELES DE IRRADIACIÓN CON RAYOS GAMMA (60Co).

Abstract

This research was carried out with the purpose of evaluating the germination of savoy grass seeds (Panicum maximum), exposed to different levels of irradiation with gamma rays (⁶⁰Co) in the Faculty of Agricultural Sciences of the Technical University of Babahoyo. Savoy grass seed was used, irradiated at different levels of gamma rays (⁶⁰Co). To evaluate the variability of phenotypic characteristics of Savoy, the following variables were used: germination, plant height, chlorophyll level, leaf length, leaf width, leaf area, stem diameter, number of leaves, flowering days, yield. of dry matter. As results, it was possible to evidence the somatic effects observed in the evaluated plants, consisting of the reduction in the percentages of germination and height of the seeds, sterile seeds. The irradiation levels applied in treatments T1, T2, T3, T4 and T5 did not show significant statistical differences in all the variables evaluated. Similar results were obtained with the variable dry biomass and yields for all irradiated and non-irradiated treatments did not show statistical differences, numerically the treatment that stood out was T2 (50 Gy) and T3 (75 Gy).
