摘要: Abstract Electrophoretic patterns of soluble proteins and multiple forms esterases were studied in non-infected first flag leaves six barley cultivars showing various levels resistance to powdery mildew. Although the pattern acidic was similar for all tested, some low molecular weight observed absent leaves. The appearance genotype-dependent, irrespective stage plant development, whereas esterase showed characteristic differences, genotype. With regard different esterases, tested classified into three groups which also differed with mildew resistance: (i) Mari S Peruvian (highly susceptible mildew), (ii) Villa, Asse (adult resistant) Stamm 41 71 (moderately (iii) Rupee resistant). possible significance this correlation discussed.
