Abstract
Summary ALDESUQUY H. S. & BAKA Z. A. M. 1992. Physiological and biochemical changes in host leaf tissues associated with the growth of two biotrophic fungi growing in Egypt. - Phyton (Horn, Austria) 32 (1): 129-142. English with German summary. Two biotrophic fungi, from different groups, growing in Egypt were selected for this study, Puccinia lagenophorae, infecting Senecio glaucus and Albugo Candida infecting Cakile maritima during late infection. The intensity of growth of the two pathogens on their hosts was studied in relation to some physiological and biochemical aspects of infected leaves. The infection of Senecio caused a significant decrease of relative water content, while the infection of Cakile caused a nonsignificant decrease of the same parameter. The ionic content (Na+, K+, Ca2+) of infected leaves of both Senecio and Cakile was greatly reduced. Also, there was a decrease in pigments (chl a, chl b and carotenoids) in infected leaves of both Senecio and Cakile. In addition, carbohydrate content (sucrose, reducing sugars and polysaccharides) was significantly decreased in infected leaves of Senecio but increased in case of Cakile. Seventeen amino acids were detected in both healthy and infected leaves of Senecio and Cakile. It was found that, most of these amino acids decreased after the infection by the two pathogens except the increase of some amino acids such as phenylalanine and histidine in case of Senecio and glycine, alanine, methionine and histidine in case of Cakile. The variation of these results were discussed in relation to the growth and behaviour of the two pathogens on their hosts.
