Abstract
Abstract M 2 progenies from geranium ( Pelargorium X hortorum L.H. Bailey), which had been irradiated with 1, 2, and 3 krads of acute gamma radiation, were evaluated for stem and branch length and number of leaves and branches. After several weeks, the progenies from plants irradiated with 2 and 3 krads were significantly shorter than the controls. Progenies treated with 3 krads were 21% shorter and exhibited a 30% reduction in branch length compared to the controls at the termination of the experiment. These effects were similar to those observed in the M 1 generation. Leaf and branch number did not differ significantly among progenies of the irradiated plants. It is suggested that gamma radiation induced changes in endogenous levels of GA in the M 1 plants, and these changes were transmitted to the M 2 progenies.
