A process for improvement of the soil by reducing microbially formed ethylene in the soil by bringing compounds which bind ethylene or of which it is known that they inhibit ethylene biosynthesis between S-adenosyl-L-methionine and 1-aminocyclopropane-carboxylic acid or 1-aminocyclopropane-1-carboxylic acid and ethylene respectively, into the soil zone relevant for the root growth of higher plants and allowing them to act there on the soil microorganisms.

Process and composition for soil improvement by reducing microbially formed ethylene in the soil

The sugar content of plants is increased by a method in which the plants are treated, from 1 to 15 weeks prior to harvesting, with a compound of the formula (I) ##STR1## where R.sup.1 is alkyl of 1 to 4 carbon atoms, R.sup.2 is alkyl of 1 to 4 carbon atoms, unsubstituted or halogen-substituted alkenyl of 3 to 5 carbon atoms or alkynyl of not more than 5 carbon atoms, R.sup.3 is a non-aromatic heterocyclic structure which has 5 to 7 ring members and no double bonds or one double bond in a heterocyclic ring, contains 1 or 2 hetero atoms from the group consisting of sulfur and oxygen, and can be substituted by alkyl of not more than 3 carbon atoms, and X is H or C00-alkyl, or one of its plant-tolerated salts.

Increasing the sugar content of plants

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.

Influencing plant growth

New agents for regulating plant growth, especially for reducing the height of plants, containing a mixture of a quaternary substituted thianium or ammonium salt and a phosphonic acid derivative.

Plant growth regulators

Agents for regulating plant growth, especially for improving abscission, which contain substituted ammonium salts or substituted fatty acid amides, and a process for improving abscission with these agents.
