ASSESSMENT OF THE ACTION OF DEPOSIT MYCOFLORA ON VICIA FABA L BEANS FROM SUCEAVA GENEBANK’S COLLECTION

Diana BATÎR RUSU, Danela MURARIU

Abstract

This study consisted in a phytopathological evaluation of epiphyte and endophyte mycological flora which appeared on Vicia faba seeds placed on two types of substrates (CGA medium and blotting paper). The 30 populations of faba bean resulted from the active collection of Suceava Genebank and conserved for different time intervals (8, 18 and 23 years), in controlled atmosphere storages (T=+40C; relative air humidity = 30 - 40%). Micromycets 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 were to establish the influence of the conservation period on the activity of micromycets 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.
