Abstract

Plant-growth regulating compositions and methods having strong effects on plant growth, containing a heterocyclic sulfonium salt of the formula ##STR1## in which R is alkyl; substituted alkyl; alkenyl; alkynyl; cycloalkyl; or aralkyl which is optionally substituted in the aryl moiety; PA1 A.sup.- is one equivalent of an anion; and X is oxygen or the group N.sup.+ R'R" A.sup.- or S.sup.+ -R'" A.sup.- in which PA1 A.sup.- is identified as above; PA1 R' and R", which may be identical or different, are each alkyl of up to 6 carbon atoms; and PA1 R'" is defined as R or can be, together with R, an ethylene linkage.
