| Popis: | Nine isolates of Ascochyta rabiei from Pakistan were grown in still culture on Czapek Dox liquid medium supplemented with aqueous extracts of the seed of one of two cultivars, a desi (6153) or a kabuli (Cypressa). Toxicity of the culture filtrates from both media was assayed with cells isolated from the leaves of both cultivars and concentrations of the phytotoxins. solanapyrone A and solanapyrone C, in the filtrates were determined by high-performance liquid chromatography (HPLC). For eight of the fungal isolates, toxicity and solanapyrone concentration were correlated, r varying from 0·383 to 0·859 according to medium and assay cultivar, but culture filtrates of another isolate, which was the most active by more than an order of magnitude, contained cytochalasin D but neither of the solanapyrones. |
