Abstract

(...) Light and electron microscopy showed that A. flavus var. columnaris was able to invade the internal tissues of the emerging shoot via wounds in the surface (caused by physical injury during germination in the sand or vermiculite); through the stomata; and also by penetrating the apparently intact cuticle. Although the mycelium was concentrated in the space between the coleoptile and the primary leaves, both tissue types were infected. In the parallel study, seeds that had been infected in the same manner were allowed to germinate on sterile filter paper before being planted in sterile soil (...)
