Suppression of Floral Induction by Inhibitors of Steroid Biosynthesis
This paper concerns a class of metabolic inhibitors
which possess the ability to suppress the flowering
of short-day plants and which appear to do
so by interfering with generation of the flowering
stimulus by the leaf. The inhibition of flowering
with which we are here concerned is thus different
from that elicited by 5-fluorouracil and 5-fluorodeoxyuridine.
These two substances act by preventing
successful receipt by the bud of the leaf-produced
floral stimulus (4, 17). The substances here reported
as active in inhibition of the generation of
flowering stimulus by the leaf are of further interest
in that they are inhibitors of the biogenesis of steroids
