A series of ester and salt derivatives of fluorene-9-carboxylic acid and fluorene-1-carboxylic acid exhibit significant plant growth regulating properties, useful in controlling the size, shape, dormancy time, flowering time and/or fruit setting of plants, depending upon the concentrations used. They may also be used to control the growth rate, texture and color of turf grass. Presently preferred compounds include the cis-2,5-dimethylpyrrolidine salt of 1-fluorenecarboxylic acid, 9-cis-2,S-dimethyl-1-pyrrolidinyl-2-chlorofluorene-9-carboxylic acid, methyl ester, the 2,6-dimethylpiperidine salt of 1-fluorenecarboxylic acid, and the cis-2,5-dimethylpyrrolidine salt of 9-hydroxyfluorene-9-carboxylic acid.
芴-9-羧酸和芴-1-羧酸的一系列酯类和盐类衍生物具有显著的植物生长调节特性,可用于控制植物的大小、形状、休眠时间、开花时间和/或坐果,具体取决于使用浓度。它们还可用于控制草坪草的生长速度、质地和颜色。目前优选的化合物包括 1-芴甲酸的顺式-2,5-二甲基吡咯烷盐、9-顺式-2,S-二甲基-1-吡咯烷基-2-氯芴-9-羧酸甲酯、1-芴甲酸的 2,6-二甲基哌啶盐和 9-羟基芴-9-羧酸的顺式-2,5-二甲基吡咯烷盐。
