Abstract

Apple proliferation (AP), Candidatus Phytoplasma mali, is listed as a quarantine diseasein Norway. Until 1996 it was never reported in the country. A national survey inthe years 1996 and 1997 revealed 14 diseased trees in orchards throughout the country.In September 2010, however, a new more serious outbreak of AP occurred in the countyof Sogn og Fjordane. This has led to new surveys and a new focus on this diseasein Norway.

Abstract

Fungi are the main degraders of organic matter and are associated symbiotically with over 80% of terrestrial plants (Smith and Read 1997). Thus, the extent of the mycelial network is an indicator of the decomposing or symbiotic activity. Although the importance of fungi in soil is undisputable, the determination of the extent of hyphal mats and the hyphal biomass is difficult to assess. Methods for estimating hyphae in soil are mostly based on the gridline intersect method originally developed to determine the root length or recently by measuring of the ergosterol content, fungal sterol found in the cell membranes....
