• Seminal roots of Zea mays L. show curved growth, i.e. waving, meandering and spiral growth, when water cultured. Root curvature was accelerated by exogenously applied indole-3-acetic acid at 10^<-9> M and gibberellic acid at 10^<-6> M; this curvature disappeared when 10^<-7> M p-chlorophenoxyisobutyric acid was added. Roots curved more when the tops of seedlings were exposed to light than when the tops of seedlings were covered. These results suggest that auxin may induce root curvature.
