ABSTRACT: The study aims to determine the tolerance degree of several chestnut hybrid species and clones to P. cinnamomi. Thus, a comparative assay was carried out in which C. sativa and C. mollisima and Euro hybrid Asiatic clones, both provided by the TRAGSA nursery in Ourense, were studied in two development stages - acclimatized plants and explants. Acclimatized plants were acclimatized in the Estación Fitopatolóxica do Areeiro chambers and were later inoculated with growing P. cinnamomi mycelium, which was added to the substrate surface by diffusion. Explants, once propagated and in vitro rooted, were inoculated with mycelium pieces containing fungus sporangia. Plants were analyzed to check pathogen reisolation, a process performed at the EFA laboratories. Susceptibility differences were observed among species and chestnut clones, as well as between both inoculation methods, finding that the hybrid clone HS and C. mollissima were the less susceptible to P. cinnamomi attack.. Keywords: "in vitro", explants, clon HS, C. mollisima |
