摘要:

Administration of exogenous cytokinins to lettuce seedlings germinating in the light, inhibits the accumulation of chlorophyll in the cotyledons. This action seems to be independent from the type of modification in N-6 or N-9 position of the purine ring of cytokinins. This fact suggests that the purine ring itself could be involved in this particular cytokinin action. The biochemical event(s) affected are unknown.
