Abstract
Jendartearen elikadura beharrizanak asetze aldera, eta egungo aldaketa globalaren aurrean, agroekosistemen kalitatea eta emankortasuna bermatu nahi badira, lurzoruko mikroorganismoen biodibertsitatea indartzea funtsezkoa da; tartean, landareekin sinbiosi mutualistak eratzen dituzten onddo mikorriziko arbuskularrena. Nekazaritza ereduak baduenez aurreko guztian eragina, eta agrobiodibertsitatearen kontra, oro har, geroz eta labore-barietate gutxiago erabiltzen denez, nekazaritza konbentzionalak eta ekologikoak Arabako lautadan ekoizten diren lau barietateren mikorrizazio mailan duten eragina aztertu da. Nekazaritza ekologikoak dibertsitatea sustatzen duela ikusi da, eta, ondorioz, mikorrizazioa areagotzeaz gain, barietate batzuen mikorrizek egoera funtzional hobea erakutsi dute.
Strengthening the biodiversity of soil microorganisms, including arbuscular mycorrhizal fungi (which form mutualistic symbioses with plants), is essential to meet the food needs of society and to ensure the quality and fertility of agroecosystems given the current global change. Since the agricultural model affects all of the above, and contrary to agrobiodiversity, the use of crop varieties, in general, is decreasing, the influence of conventional and organic farming on the degree of mycorrhization of four varieties produced in the Llanada Alavesa has been analysed. Organic agriculture promoted diversity, which not only increased mycorrhization, but also the mycorrhizae of some varieties showed a better functional state.
