Effect of gamma radiation of 60Co on sunflower plants (Helianthus annuus L.) (Asteraceae), from irradiated achenes
Genetic variability, Mutation, phenotype
In order to know the effect of 60Co gamma irradiation, in the sunflower crop, were irradiated achenesin the Transelektro LGI-01 in the Instituto Nacional de Investigaciones Nucleares. The data wasevaluated under a completely randomized design, where the treatments were 0, 100, 200, 300, 400,500, 600, 700, 800 and 900 Gy and four repetitions (10x4) = 40 experimental units. The responsevariables were: plant height, root length and volume, dry biomass. The results indicated thatgermination and sprouting decreased as the radiation increased, adjusting these to a quadratic model.Plant height, length, root volume and dry biomass decreased at high doses. From this investigation itwas concluded, that doses of 100 and 200 Gy, have a stimulating effect on plant height and root length,being an important agent, to induce genetic variability in sunflower.
