Summary
1. β-(Indol-3-yl)acetic acid (IAA) and butyric, phenylbutyric, α-aminobutyric, and γ-aminobutyric acids have an activating effect on the malate dehydrogenase (MDH) of dormant and sprouting cotton seeds, while γ-aminobutyric acid inhibits the MDH of the sprouting seeds.
2. The maximum MDH activity is found on the fifth day of sprouting of cotton seeds. The preliminary steeping of the seeds in solutions of organic acids changes the time of maximum activity to the first and second days.
