appropriate management of soil phosphorus (p) fertility in highly calcareous soils of iran as around the world should rely upon sound knowledge about the phosphorus reserve and its bioavailability. despite numerous reports on the positive effects of vesicular arbuscular mycorrhizae (vam) fungi on phosphorus uptake which is associated to ectomycorrhiza as a branch of two major branches of group ...

Data on the diversity and distribution of enzyme activities in native ectomycorrhizal (ECM) communities are inadequate. A microplate multiple enzymatic test was developed which makes it possible to measure eight enzyme activities on 14 individual, excised ECM root tips. Hydrolytic and oxidative enzymes are involved in the decomposition of lignocellulose, chitin and phosphorus-containing organic...

A significant fraction of carbon stored in the Earth's soil moves through arbuscular mycorrhiza (AM) and ectomycorrhiza (EM). The impacts of AM and EM on the soil carbon budget are poorly understood. We propose a method to quantify the mycorrhizal contribution to carbon cycling, explicitly accounting for the abundance of plant-associated and extraradical mycorrhizal mycelium. We discuss the nee...

Seedling quality is an important input affecting the outplanted seedling performance. Morphological attributes and association with symbiotic ectomycorrhizal (ECM) fungi belong to influential traits determining quality. In this study, effect of pre-sowing applied commercial additives Ectovit (containing hydrogel ECM fungi), Mycorrhizaroots (ECM nutrients) Vetozen (natural mineral fertilizer) on...
