Abstract

A group of xanthine derivatives and a novel analog of 6-benzylaminopurine (BAP) were tested for their ability to inhibit conjugation of cytokinin with alanine in soybean leaves. 3-(5-Hexenyl)-1,7-dimethylxanthine was found to be the most effective xanthine derivative. Although it had no senescence-retarding activity when applied alone to soybean leaves, it enhanced the action of BAP.
