The invention relates to new plant growth regulating compositions, which contain as active agent 0.001 to 95% by weight of one or more compound(s) of the general formula (I), ##STR1## wherein R.sup.1 and R.sup.2 each represent hydrogen atom, a C.sub.1-5 alkyl group, a C.sub.5-7 cycloalkyl group, an aryl group, a halogen-substituted aryl group, an aralkyl group, a C.sub.2-5 alkenyl group or a C.sub.2-5 alkynyl group, or

Plant growth regulating compounds and compositions and a process for the

The invention relates to new N-substituted amino propane sulfonic acid derivatives of the Formula I ##STR1## and salts and hydrates thereof, a process for the preparation thereof and plant growth regulating agents comprising the same wherein

N-substituted amino propane sulfonic acid derivatives and plant growth

Racemic or optionally active 2-(propargyloxyimino)-1,7,7-trimethyl-bicyclo[2,2,1]heptane of the formula (I) ##STR1## or a mixture of these isomers is prepared by reacting a racemic or optically active 1,7,7-trimethyl-bicyclo[2,2,1]heptane derivative of the general formula (II), ##STR2## wherein Y stands for oxygen atom, sulfur atom or oxime group, with a propyne derivative of the general formula (III),
