Heterocyclic sulfonium salt containing plant-growth regulant compositions

摘要

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