Occurrence of Fusarium culmorum (W.G.Sm.) Sacc. in the Rhizosphere of Oats

Abstract

As a result of the techniques employed, many of the studies on the occurrence of fungi in rhizospheres have been restricted to considerations of the soil adjacent to roots (rhizosphere soil) as a uniform microhabitat from crown to tip of the root system. Although this may be valid for young roots it is unlikely to be so for older roots, where very different rhizosphere effects will operate at the tip from those exerted at the crown. The aim of ecological studies on the rhizosphere mycoflora should be to provide information comparable to that given by Harley and Waid¹ in their study of mycofloras of the surfaces of beech roots.
