Experiments concerning the effects of benzyladenine applications on the growth and senescence of leaves have been carried out with cuttings of bean seedlings. By measuring the interactions between leaves, it was found that this kinin not only can stimulate the growth of a treated whole leaf, but it can bring about the inhibition of growth in other untreated leaves on the same plant. Consistent, with the apparent mobilizing actions of this chemical, it was found that applications to one or more leaves would induce the senescence of untreated leaves in a manner similar to the senescence‐inducing effects of stem apices and flowers and fruits. The experiments suggest that the mobilization effects due to natural kinins in such centers in the intact plant may provide endogenous stimuli of leaf senescence.
