Abstract
IT is well established that the germ tubes of urediospores of rust fungi penetrate host tissue exclusively through stomata. The factors affecting their growth towards stomata are not known. Our observation of a directional growth of urediospore germ tubes of Puccinia antirrhini and other species of rust fungi on surface of leaves of Antirrhinum majus may have some bearing on this problem.
