Abstract/Description: | Biochemical nature of 25 isolates of Alternaria helianthi were characterized based on production of total sugars, total proteins,total free amino acids and phytotoxins. The estimation of all parameters reflected significant variation among all. The isolate Ah-25 produced maximum concentration of total sugar (13.28 mg), while minimum concentration was noticed in Ah-13 (3.10 mg). Similarly, the total proteins content was found highest in the isolate Ah-25 (21.43 mg) and lowest with the isolate Ah-15 (9.53 mg). Among the isolates, the total free amino acids ranged between 5.67 mg (Ah-15) to 21.24 mg (Ah-21). The phytotoxicity of the crude toxin was tested by adopting detached leaf technique at different concentrations.None of the tested isolates have produced symptoms at 50 ppm concentration. However, the typical symptoms of necrotic lesions were observed at 100 ppm with nine isolates (Ah-1, Ah-2, Ah-4, Ah-7, Ah-12, Ah-17, Ah-21, Ah-24 and Ah-25). Further, the strains were found to vary in their biochemical composition between all the isolates under the study. |
