Abstract
Cinchomeronic acid (CA) at 10–100mM enlarged the leaf area of radish seedlings, and at 10 mM, it increased stem elongation. CA was found in free form in the plants. The effects of CA analogs on the growth of radish seedlings were investigated. Quinolinic acid and dinicotinic acid increased stem elongation, but at 10 mM, isocinchomeronic acid, dipicolinic acid, lutidinic acid, pyridine monocarboxylic acids, and pyrazine monocarboxylate inhibited elongation. Two carboxyl groups, one at the C-3 position of the pyridine ring and the other at the C-2, C-4, or C-5 position, seem to be required for increased growth. Growth was inhibited by pyridine monocarboxylic acids regardless of the position of the carboxyl group, and growth was also inhibitory by pyridine dicarboxylic acids with one carboxyl group at C-2 and the other at a position other than C-3.
