摘要: Summary Distribution and gradient analysis of Ink disease caused by Phytophthora cambivora were studied over a 2 years period in chestnut forest Italy. incidence, severity tree mortality increased during the forest. Disease descriptors landform datasets analysed Geographic Information System software displayed as multilayer thematic map. Indices dispersion empirical models used to study spatial distribution investigated area. Semivariograms interpolate data map disease. A logical dependence variables was found. occurred preferentially along natural drainages routes where multicyclic inoculum build up likely occur. negative relationship found between with respect distance from drainage.
