Germination of Witchweed (Striga lutea Lour.): Isolation and Properties of a Potent Stimulant

C E Cook et al. Science. .

Abstract

A crystalline germination stimulant (trivial name strigol) for the rootparasite, witchweed (Striga lutea Lour.), has been isolated from cotton rootexudates and characterized as a C(19)H(22)O(6) compound. Although apparently different from known plant hormones, the stimulant is active at hormonal levels, causing germination at concentrations less than 1O(-5) part per million.
