Root curvatures induced by culture filtrates of Aspergillus niger

R W CURTIS. Science. .

Abstract

Evidence obtained by paper chromatography indicates that corn root curvatures caused by culture filtrates of Aspergillus niger are caused by the same compound which causes curvatures and malformations on the stems and petioles of bean plants. The R(f) values obtained for this compound were substantially different from those of indoleacetic acid.
