Abstract

GA3, cyclic AMP as well as 3′-AMP and 5′-AMP induced the formation of floral buds inImpatiens balsamina under strictly non-inductive photoperiods. While photoperiods and treatments with GA3 or AMPs did not much affect acid phosphatase activity, AMPs increased the activity of alkaline phosphatase both in the stem and the leaves under both photoperiods. The phosphatase activity of the water- and GA3-treated plants under inductive photoperiods was higher than that of the plants of the respective treatments under non-inductive photoperiods. GA3 as well as all the three AMPs induced both in the stem and the leaves the formation of new isoenzymes of both these enzymes under both photoperiods.
