Abstract
Tricyclic nitrogenous compounds having strong plant growth regulating properties are disclosed. The compounds display the general formula ##STR1## wherein A is one of several nitrogen-containing radicals, R.sup.1, R.sup.2, R.sup.3 and R.sup.4 are selected from various recited aliphatic, aryl, araliphatic and heterocyclic groups. R.sup.3 and R.sup.4 may also together form one of a number of nitrogen, sulfur and oxygen containing radicals. These compounds have a variety of uses, including the reduction of plant growth height without harm to the plant.
