Abstract
RECENTLY, Fletcher, Alcorn and Raymond1 presented evidence that gibberellins had no effect on the nodulation of white clover (Trifolium repens) grown either in aseptic agar or in soil. In concentrations from 1 to 1,000 p.p.m., gibberellic acid was also without effect on the growth of the nodule-forming organism Rhizobium trifolii. These combined results seemed to contradict a previous report of Thurber, Douglas and Galston2, who had found a marked depressive effect of potassium gibberellate on nodulation in dwarf beans (Phaseolus vulgaris).
