  A composition for regulating plant growth, the active ingredient of which is an ester of oxaloacetic acid or a salt thereof, or derivatives thereof, wherein the ester of oxaloacetic acid has the given formula, where R1 and R2 are independently selected from a series of C1-C18 alkyl groups, and wherein the content of the active ingredient corresponds to a concentration of from 10-11 M to 10-3 M. The active ingredients and compositions for regulating plant growth allow for treating plants in order to stimulate the growth thereof and achieve such advantages as increased yields, improved plant quality, improved nutrient absorption and enhanced stress resistance, while allowing such advantages to be achieved using a relatively small amount of an active ingredient(s) which is/are biodegradable and environmentally friendly.

  一种调节植物生长的组合物，其活性成分是草酰乙酸酯或其盐或其衍生物，其中草酰乙酸酯具有给定的式，其中 R1 和 R2 独立地选自一系列 C1-C18 烷基，活性成分的含量相当于 10-11 M 至 10-3 M 的浓度。调节植物生长的活性成分和组合物可以对植物进行处理，以刺激植物的生长，达到提高产量、改善植物质量、改善养分吸收和增强抗逆性等优点，同时只需使用相对少量的活性成分即可达到上述优点，而且活性成分可生物降解，对环境友好。
