Abstract

It was shown that young seeds of Lupinus luteus contained some unknown cytokinins besides dihydrozeatin, which strongly stimulated the growth of cultured tobacco tissue (Nicotiana tabacum cv. Wisconsin No. 38). These unknown cytokinins were purified partially and studied with paper chromatography and bioassay. One of them is water-soluble and hydrolysis of it yields more active water-soluble cytokinin, but neither dihydrozeatin nor its ribonucleoside. This unknown cytokinin is not dihydrozeatin ribonucleotide, and may be a novel cytokinin. Another unknown cytokinin is not water-soluble, but extractable with n-butanol. On paper chromatograms this cytokinin locates closely to dihydrozeatin ribonucleoside, and gives a positive color reaction specific to pentose. Hydrolysis of it yields an active component indistinguishable from dihydrozeatin. It seems likely that this cytokinin is dihydrozeatin ribonucleoside.
