EFFECT OF IRRADIATION WITH 60Co GAMMA RAYS IN GLADIOLUS (Gladiolus communis L.) RED AND WHITE CULTIVAR
IRRADIATION EFFECT IN GLADIOLUS
Keywords:
Irradiation, stimulation, radiosensitivity, GR30.Abstract
Irradiation with 60 Co is an alternative for the generation of genetic variability in gladiolus to induce desirable phenotypic characteristics. 10 irradiation levels were evaluated in corms of red and white borrega gladiolus cultivars. The trial was developed under greenhouse conditions, in order to evaluate the stimulation exerted in days to sprout, greenness, plant height, greenery and stem thickness. The 30 and 70 Gy treatment stimulated the expression of the height and thickness of the stem were stimulated above the control in the two cultivars, which was corroborated with the 30% growth reduction analysis. The doses of 80 to 100 Gy stimulated lower height and thickness of the stem, reaching a reduction of over 30% compared to the control. In white borrega, greater greenness and stem thickness were expressed, while in red borrega, greater plant height was expressed compared to the control.
