Abstract

Irradiation of seeds of various crop plants with 3000 r of X rays seemed to stimulate the growth of lettuce and cabbage, but more critical tests showed no significant effect of the irradiation. Irradiation of Gladiolus bulbs with 4000 r of X rays did result in significantly earlier flowering.
