Abstract
Semințele din linia homozigotă AG07-2008 din grupa de germoplasmă Lacaune au fost expuse la doze de radiație X de la 25 la 500 Gray(Gy), cu o diferență de 25Gy dintre variante. Variantele au fost semănate pe parcele cu suprafața de 5m2, câte 30 de semințe iradiate. Controlul a fost reprezentat prin 2 parcele, în total 22 parcele (110m2). În perioada de vegetație a fost măsurată înălțimea plantei, diametrul și lungimea știuletelui. Rezultatele arată o corelație inversă puternică între doza de iradiere și înălțimea plantei și o influență mai scăzută a dozei de iradiere asupra parametrilor știuletelui.
Seeds from the homozygous line AG07-2008 in the Lacaune germplasm group were exposed to X radiation doses from 25 to 500 Gray (Gy), with a difference of 25Gy between the variants. The variants were sown on plots with an area of 5 m2, 30 irradiated seeds each. The control was represented by 2 plots, in total 22 plots (110 m2). During the vegetation period the height of the plant, the diameter and length of the corn cob was measured. The results show a strong negative correlation between irradiation dose and plant height and a lower influence of irradiation dose on maize cob parameters.
