Tuber forming substances from plants and microorgansms were surveyed using a bioassay consisting single-node stem segment culture. From leaves of Jerusalem artichoke (Helianthus tuberosus. L), two cyclopentanoid fatty acids, jasmonic acid(2) and methyl tuberonic acid glucoside(3), and six polyacetylene compounds(4-9) were isolated and the chemical structures were determinded. From the fungi, Lasiodiplodia theobromae IFO 31059, a cyclohexene epoxide(10) and mellein(11) were isolated. Cyclopentanoid fatty acids(2,3) have revealed tuber forming activity at more than 10^<-5>M and cyclohexene epoxide(10) at 10^<-4>M. Polyacetylene compounds(4-9) and mellein(11) have displayed weak activity.
