Preliminary field tests by Plant Growth Development Corporation (PGDC) have established that dramatic increases in plant growth can be obtained by foliar treatments of plants with preparations of succinic acid derived from fermentation. Subsequent tests in the greenhouse have shown that fermentation succinic acid is much more active at stimulating plant growth than equivalent amounts of synthetic succinic acid. Analysis of other components in fermentation succinic acid preparations showed that gamma aminobutyric acid (GABA) is also an ingredient. Laboratory and greenhouse tests have shown that synthetic GABA stimulates plant growth, and that bioactivity is synergistically increased by combination with succinic acid. Although GABA is ubiquitous in the plant kingdom, its function is unknown. Funding is being requested to establish the most effective way for using formulations containing GABA to increase plant growth and productivity, and to elucidate the mechanism of GABA bioactivity.

由植物生长发展公司（PGDC）进行的初步田间试验已经证实，通过用发酵产生的琥珀酸制剂对植物进行叶面处理，可以获得植物生长的显著增加。随后在温室中的测试表明，发酵琥珀酸在刺激植物生长方面比等量的合成琥珀酸更活跃。对发酵琥珀酸制剂中其他成分的分析表明，γ-氨基丁酸（GABA）也是一种成分。实验室和温室试验表明，合成GABA刺激植物生长，与琥珀酸结合可协同提高生物活性。虽然GABA在植物界普遍存在，但其功能尚不清楚。目前正在申请资金，以确定使用含有GABA的制剂提高植物生长和生产力的最有效方法，并阐明GABA生物活性的机制。
