Abstract


In 1995–1998 two field experiments were carried out on a sandy soil. Supplemental irrigation and mineral fertilization modified the yield of pea and white lupine. Higher yield increases gave pea. Furthermore, the applied practices influenced both the anatomical and morphological features of both plant species. Leaves of irrigated and well fertilized plants were bigger and had an increased number of stomata of larger dimensions. Leaves of both plant species harboured numerous populations of spores of microscopic fungi. More abundant spore populations of these fungi were isolated from the white lupine leaves. The most frequently revealed spores were those of the genera Cladosporium and Uromyces. In white lupine, the abundance of spores associated with leaves increased due to the irrigation applied, whereas in pea following the use of fertilizers. Additionally, irrigation increased the number of spores of arbuscular fungi of the genus Glomus in the root zone of pea, but decreased their occurrence among roots of white lupine.
