Abstract
New plant growth regulators, including compounds and compositions, and methods of use including for promoting root growth. The compounds are carotenoid oxidation products, and a preferred example is 3-OH-β-apo-13-Carotenone. A method comprising promoting the growth of at least one plant with use of an effective amount of at least one composition comprising an effective amount of at least one compound which is represented by A-B-C, wherein B is a bivalent polyene moiety, A is a monovalent moiety linked to B by a six-membered carbon ring, wherein the ring has at least one substituent linked to the ring by an oxygen atom, and C is a monovalent moiety linked to B by a carbonyl group. Synergistic effects can be used with combinations of compounds.

A method comprising promoting the growth of at least one plant with use of an effective amount of at least one composition comprising an effective amount of at least one compound which is represented by A-B-C, wherein B is a bivalent polyene moiety, A is a monovalent moiety linked to B by a six-membered carbon ring, wherein the ring has at least one substituent linked to the ring by an oxygen atom, and C is a monovalent moiety linked to B by a carbonyl group.
A composition for promoting the growth of at least one plant, the composition comprising (i) at least one compound which is represented by A-B-C, wherein B is a bivalent polyene moiety, A is a monovalent moiety linked to B by a six-membered carbon ring, wherein the ring has at least one substituent linked to the ring by an oxygen atom, and C is a monovalent moiety linked to B by a carbonyl group;
- and (ii) at least one delivery compound which is different from compound (i) which facilitates delivery of the compound for promoting the growth of at least one plant.
A compound represented by structure Z:
- wherein S1 is an alkyl or a carboxylic acid group;
- wherein S2 is an alkyl, carboxylic acid, or —CH2OH group;
- wherein S3 is an alkyl, a carboxylic acid, or a —CH2OH group;
- and wherein S4 is an alkyl, carboxylic acid, or —CH2OH group, with the proviso that S1, S2, S3, and S4 are each not methyl.
