摘要:
A process for regulating plant growth, wherein the plants, the seed or the soil are treated with a polycyclic nitrogen-containing compound of the formula ##STR1## R.sup.2 is --N.dbd.N-- or --NH--NH, and R.sup.3 is ##STR2## or phenyl which is substituted by halogen, fluoroalkyl of 1 to 2 carbon atoms, NO.sub.2 or C.sub.1 -C.sub.3 -alkyl, the equivalent of less than 100 g of active ingredient being employed per hectare.
摘要:
Phenylpropylammonium salts of the formula ##STR1## where R.sup.1 denotes for instance alkyl or halogen, R.sup.2 denotes for instance alkyl or alkoxy, R.sup.3 denotes alkyl, alkenyl or alkynyl of up to 6 carbon atoms, R.sup.4 and R.sup.5 denote hydrogen or alkyl of up to 3 carbon atoms, m denotes one of the integers 0, 1, 2 and 3, n denotes one of the integers 0, 1 and 2, o denotes one of the integers 4, 5 and 6, X.sup..theta. denotes an anion, and the dashed bond may be hydrogenated when n is 0 or 1, and is hydrogenated when n is 2; the preparation of these compounds; and agents for regulating plant growth containing these compounds as active ingredients.
摘要:
Substituted alkylammonium salts of the formula ##STR1## where Ar denotes substituted phenyl, X denotes oxygen or sulfur, n denotes one of the integers 0, 1 and 2, B denotes bicyclic quinuclidine, bicyclic pyrrolizidine or substituted ammonium, and Z denotes the anion of a nonphytotoxic acid, the manufacture of these compounds, and their use as plant growth regulators.
摘要:
New and valuable polycyclic compounds which contain nitrogen-containing rings and have a strong action on plants, agents for influencing plant growth containing these compounds, and a method of influencing plant growth with these compounds.
摘要:
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.
