Plant growth-regulating compounds of the formula ##STR1## wherein X and Y are separately oxygen, sulfur, N-B where B is hydrogen, lower alkyl, or acyl; R and R' are separately lower alkyl, acyl, amido, or form a cycle with ##STR2## corresponding to the formula ##STR3## in which R.sub.1, R.sub.2, R.sub.3, and R.sub.4 are separately hydrogen, lower alkyl, halogen-substituted lower alkyl, NO.sub.2, hydroxy or lower alkoxy, and A is a single bond or an alkylene chain of 1-4 carbons, or an alkylene chain of 1-4 carbons interrupted by oxygen or N-B' where B' is hydrogen, lower alkyl, lower halogen-aided alkyl, lower hydroxylated alkyl, lower acyl, or a cycle having in common with the preceding cycle 1 or 2 carbon atoms and containing from 3 to 6 carbons, up to 2 oxygens and/or a group N-B, or a cycle corresponding to the formula ##STR4##
式为##STR1##的植物生长调节化合物,其中X和Y分别为氧、硫、N-B,其中B为氢、低碳基或酰基;R和R'分别为低碳基、酰基、酰胺基或形成与##STR2##对应的环式##STR3##,其中R.sub.1、R.sub.2、R.sub.3和R.sub.4分别为氢、低碳基、卤素取代的低碳基、NO.sub.2、羟基或低碳氧基,A为单键或1-4碳的烷基链或由氧或N-B'(其中B'为氢、低碳基、低卤素辅助烷基、低羟基化烷基、低酰基)中断的1-4碳的烷基链,或与前述环式共有1或2个碳原子并含有3至6个碳原子、最多2个氧原子和/或一个N-B基团的环式##STR4##。
