    • Provided are compositions and methods of improving a plant growth factor. The compositions and methods contain combinations of plant growth regulators such as plant growth retardants and inhibitors of ethylene biosynthesis or action. The ethylene inhibitors comprise substituted oxime-ethers having the general formula: ##STR1## 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, aminoethoxyvinylglycine, rhizobitoxine, silver ions (e.g. silver thiosulfate), and 2,5-norbornadiene. 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 prohexadione-Ca) and daminozide. Low rate application of the methods and compositions are preferred.
    • 提供改善植物生长因子的组合物和方法。 组合物和方法包含植物生长调节剂如植物生长阻滞剂和乙烯生物合成抑制剂或作用的组合。 乙烯抑制剂包括具有以下通式的取代的肟 - 醚:其中R 1和R 2彼此独立地为C 1 -C 6烷基,n为2或3,R 3为氢 或C 1 -C 6 - 烷基。 乙烯生物合成或作用的具体抑制剂包括:{[(异丙叉) - 氨基]氧基} - 乙酸-2-(甲氧基)-2-氧代乙酯,{[(异丙叉) - 氨基]氧基} - 乙酸-2- (异己基) - 氨基]氧基} - 乙酸-2-(异丙氧基)-2-氧乙酯(甲氧基)-2-氧代乙基酯,[(异丙叉) 乙酸,氨基氧乙酸,氨基乙氧基乙烯基甘氨酸,根瘤菌素,银离子(例如硫代硫酸银)和2,5-降冰片二烯。植物生长阻滞剂包括:具有季铵,鏻或锍部分的化合物,例如氯代氯铵和氯代氯铵;化合物 含有含氮杂环,如多效唑,单康唑和氰霉素;化合物如酰基环己烷二酮(例如,三氮芥 - 乙基和己酮二酮-Ca)和达米诺肼。优选使用该方法和组合物。
