Assessment of the impact of the cultivation of different cultivars of maize, including Bt-maize varieties, on soil- and plant-associated microbial and fungal functional communities
communication orale invitée; We will present a synthesis of the results of our study aiming at evaluating the impact of the cultivation of different maize genotypes (Monumental, DKC3420, DK315, DKC5143, DKC5783) and of corresponding Bt-maize genotypes tolerant to the pyrale production (Mon810, TXP138-F, DKc3946, DK5018, DKc5783Bt), on soil microflora. This analysis has been conducted on three compartments: the soil, the rhizosphere (defined as the soil in contact with the root) and the root (colonisation by arbuscular mycorrhizal fungi).This study has been performed in a greenhouse experiment settled to estimate the impact produced by the cultivation of the different maize genotypes on: (i)…
L'origine de toutes les altérations superficielles du tubercule de pomme de terre est-elle vraiment infectieuse?
SPE communication orale, résumé; Deux essais en sol stérile testant le pouvoir pathogène des souches le plus fréquemment isolées et inoculées seules, et un essai en hydroponie testant l'effet de co-inoculations de 2 souches sur l'apparition des altérations ont été mis en place.
