| Abstract: | Summary Formation of green islands in the host (mustard leaves) beneath the infection-drops containing germinating conidia ofAlternaria brassicicola (Schw.) Wiltsch. has been correlated with the secretion of cytokinins by the pathogen.A. brassicicola also synthesized cytokinins in the liquid synthetic medium. Cytokinins produced in vitro were extracted, and their application on the detached mustard leaves evoked the formation of green islands. |
