Abstract
New information is being accumulated for plant-derived oxylipins, such as jasmonic acid (JA) amino acid conjugates. However, these compounds have not being examined for their activity in promoting potato tuber formation. It was found that (-)-JA had the highest activity followed cis-(-)-OPDA, (+)-4, 5-didehydroJA, cis-(+)-OPDA-l-Ile, and (-)-JA-l-Ile, -Leu, -Phe, -Val, although iso-OPDA and 3,7-didehydroJA did not exhibit activity.
