摘要：A cytokinin-autotrophic strain of tobacco callus contained cytokinin-active compounds with chromatographic mobilities on Sephadex LH-20 corresponding to ribosylzeatin, zeatin, and 6-[Delta] 2-isopentenylaminopurine. Zeatin, the apparent major cytokinin, was estimated to be present at a concentration of 10-4{micro} mol/kg of tissue. Cytokinin-autotrophic callus supplied with [14C]adenine produced radioactive components with the same chromatographic properties as zeatin and 6-[Delta] 2-isopentenylaminopurine. These components were not obtained from cytokinin-dependent tissue supplied with [14C]adenine in the same manner.
