- Abstract
This study consisted in a phytopathological evaluation of epiphyte and endophyte mycological flora which appeared on Triticum aestivum seeds placed on two types of substrates (CGA medium and blotting paper). The 30 populations of wheat resulted from the active collection of Suceava Genebank and conserved for different time intervals (8, 15 and 18 years), in controlled atmosphere storages (T=+40 C; relative air humidity = 30 - 40%). Micromycetes were evaluated by counting the infected seeds and the attack frequency was expressed as a percentage, by visual estimation of seeds surface. The target objectives of the study are to establish the influence of the conservation period on the activity of micromycetes placed on stored seeds and to settle the influence of the substrate type - CGA medium (potato - dextrose - agar) and blotting paper - on the development of fungal pathogens. Seeds studied, placed on CGA medium and blotting paper substrate, after incubation, showed a different degree of infection by fungal pathogens, depending on the type of substrate and the age of seeds. The conservation period influenced fungal pathogens longevity, meaning that the more it's higher, the level of infection is reduced. On CGA medium, in comparison with blotting paper substrate, after incubation period, was isolated a greater diversity of fungal pathogens.
