Utilization of biochemical peculiarities of fungus alternaria solani (ell et mart) sor in cellular selection of tomato species immune to alternariosis

The investigation is concerned with the strains of fungus Alternaria solani and tomato species "Beli Naliv", "Sibirski Ranniy" and "Talalikhin". The object of investigation is revelation of the possibility of cellular selection of tomato species immune to alternariosis. The researchers have studied the process of formation of phytotoxins of fungi in diverse nutritive media, obtained regenerating plants immune to cultural fungous filtrates and developed new methods for isolating and identifying fungous phytotoxins in fungus cultural filtrates and methods of cellular selection of tomato species resistant to fungus phytotoxins. The disclosed methods of isolation and identification of phytotoxins Alternaria solani have been proposed for publicationAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
