There are several procedures for isolating cytokinins which
involve a number of steps including extraction, solvent fractionation
and column or paper chromatography. Various combinations of these
procedures were tried in an attempt to isolate cytokinins from cucumber
cotyledons. It was found that with this tissue it was preferable to
omit a few steps to minimize the loss, of cytokinins activity.
The endogenous cytokinin levels in etiolated cucumber cotyledons
of different ages were estimated and compared with the capacity of
the cotyledons to produce chlorophyll after exposure to light. There
was a parallel relationship between cytokinin levels and chlorophyll
production. The cytokinin levels were highest in 8 day old cotyledons,
at which time the production of chlorophyll was also maximal. It is
proposed that cytokinins have an important role in chlorophyll production.
