| Apple replant disorders are one of the causes of the downward trend of land planted with apple orchards in Central Europe. A specific transnational survey was thus conducted on apple root associated microorganisms, aimed at increasing the knowledge regarding crop management to counteract this tendency. Soil health was evaluated using a bioassay test with root cuttings of the clonal M9 rootstock, one of the most commonly used rootstocks in Europe. Plant growth response in replant, fallow and gamma ray-sterilized soil was evaluated using soil samples taken from nine orchards selected (three per country) from specialized apple growing areas of Germany, Austria and Italy. Plant growth significantly differed between treatments but not between countries. Root... |

| APPLE • Apple replant disease in central Europe has a consistent biotic origin which is responsible for about 30% of growth reduction in multi-generation orchards. Cylindrocarpon-like fungi and Pythium spp. were shown to be primarily responsible for plant growth reduction, which was confirmed as main indicator of apple replant disease. • Pyrosequencing analysis of rhizospheric microbial communities associated to replanted orchards confirmed that Cylindrocarpon-like fungi are largely associated to replant disease; however, it also evidenced that several bacterial and fungal genera indigenous to replanted orchards are positively correlated to plant growth. This suggested that many are the indigenous resource to be exploited for increasing plant... |
