Effect of gamma radiation of 60Co on sunflower plants (Helianthus annuus L.) (Asteraceae), from irradiated achenes
subject: Genetic variability, Mutation, phenotype
description: 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.
