    Abstract: Provided compositions and methods of improving a plant growth factor. The compositions and methods contain combinations of plant growth regulators such asplant growth retardants and inhibitors of ethylene biosynthesis or action. The ethylene inhibitors comprise substituted oxime-ethers having the general formula: (see fig. I) (I) or (see fig. II) (II) where R1 and R2 independently of one another are C1-C6-alkyl, n is 2 or 3 and R3 is hydrogen or C1-C6-alkyl. Specific inhibitors of ethylene biosynthesis or action include: {¢(isopropylidene)-amino!oxy}-acetic acid-2-(methoxy)-2-oxoethyl ester, {(isopropylidene)-amino!oxy}-acetic acid-2-(hexyloxy)-2-oxoethyl ester, {{cyclohexylidene)-amino!oxy}-acetic acid-2-(isopropyloxy)-2-oxyethyl ester (methoxy)-2-oxoethyl ester,¢((isopropylidene)-amino!oxy acetic acid, aminooxyacetic acid, amninoethoxyvinylglycine, rhizobitoxine, silver ions (e.g silver thiosulfate), and 2,5norbornadiene. The plant growth retardants include: compounds with quaternary ammonium, phosphonium or sulphonium moieties such as mepiquat chloride and chloromequat chloride; compounds that contain a nitrogen containing heterocycle such as paclobutrazol, uniconazole and ancymidol; compounds such as acylcylohexanediones (e.g.,trinexapac-ethyl and prohexadion-Ca) and daminozide. Low rate application of the methods and compositions are preferred.
