The growth and economic yield of the plants can be influenced by treating whole plants, or roots, seeds, or soil, with an aliphatic acid ester of a diol having the general formula
wherein R, is hydrogen or OH, R2 is hydrogen or OH or alkyl (C1-C4), R3 is hydrogen, OH or alkyl (C1- C4), R4 is hydrogen, OH or alkyl (C1-C4), R5 is hydrogen or OH or alkyl (C1-C4), RG is hydrogen or OH, m is any number from 0 to 30, n is any number from 0 to 30, (m+n) is not more than 30 and the aliphatic acid (or, in the case of a di-ester, at least one of the aliphatic acids) contains from 4to 36 carbon atoms. Preferred compounds are mono- and di-esters in which the diol is 1,3-propane diol or (dl) 2-methyl 1,4-butane diol and the aliphatic acid is oleic, linoleic, or linolenic acid. The esters of (dl) 2-methyl 1,4-butane diol are novel compounds.

其中 R 是氢或 OH,R2 是氢或 OH 或烷基(C1-C4),R3 是氢、OH 或烷基(C1-C4),R4 是氢、OH 或烷基(C1-C4),R5 是氢或 OH 或烷基(C1-C4),RG 是氢或 OH,m 是 0 至 30 之间的任意数字,n 是 0 至 30 之间的任意数字,(m+n)不大于 30,脂肪族酸(或在二酯的情况下,至少一种脂肪族酸)含有 4 至 36 个碳原子。首选的化合物是单酯和二酯,其中二元醇是 1,3-丙烷二元醇或 (dl) 2-甲基 1,4-丁烷二元醇,脂肪族酸是油酸、亚油酸或亚麻酸。(dl) 2-甲基 1,4-丁二醇的酯类是新型化合物。
