Experimental treatment with gibberellic acid improves germination rates in sweetgum seeds, suggesting effective methods for seed propagation.
Treatment with a K-salt of gibberellic acid increased total germination of unstratified sweetgum seed over that of untreated controls. Successive increments of 75 ppm up to a concentration of 225 ppm educed progressively higher germination; thereafter germination declined. Response to gibberellic acid treatment was greatest in aqueous solution.
