Abstract: The present invention relates to compositions and methods for increasing tolerance to abiotic stress and/or for reducing the consequence of abiotic stress in a plant and/or part thereof. In some aspects, the method comprises contacting a plant and/or part thereof with a first composition comprising one or more of aminoguanidine, L-nitroarginine, L-nitroarginine methyl ester, 2,2?-bipyridine, 4-methylpyrazole, 8-hydroxyquiniline, caprylic acid, pyrazole, naringenin, kaempferol, quercetin, dodecanoic acid, and/or undecanoic acid, and/or a salt thereof; and a second composition comprising at least one dicarboxylic acid and/or a salt thereof.

Abstract: The present application is directed to methods and compositions for improving growth or yield of plants by reducing stress from abiotic factors without adversely affecting photosynthesis. In one embodiment, the compositions include particulate material and one or more plant growth regulating compounds such as non-gaseous plant hormones, amino acids and amino acid derivatives, and terpenes, and mixtures thereof. The composition is applied to at least part of the surface of the plant, forming a film on the plant. The effects of abiotic factors such as heat, cold, light, and water stress may be reduced or eliminated after application of the composition, and growth or yield may be increased while photosynthesis is not adversely affected.
