Excerpt from Studies on Clubroot of Cruciferous Plants: A ThesisIna general way the manner in which the Spores are carried is known, altho two errors are often met with in popular descriptions. For example, in a number of reports (atkinson, 1889, Carruthers, 1893, and others) 2 are statements implying that swarm-spores swim about in the water of the soil until they reach a cabbage root. In a way this is correct, but the. Average layman at once pictures the swarm-spores as traveling from row to rowof plants or even from field to field. Nothing could be more erroneous, for, as far. As dissemination is concerned, the motility of the swarm-spore plays such a slight part that it need not be considered. Its'energy is' not directed in a straight line, and the very minuteness of the organism would preclude any effective locomotion in the time that it remains alive.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
