Erdei fákon kórokozó Phytophthora fajok molekuláris azonosítása = Molecular identification of Phytophthora species pathogenic on forest trees [PDF]

open access: yes, 2008
Előző kutatásaink során beteg és pusztuló erdei fákról több mint 300 Phytophthora izolátumot tartalmazó törzsgyűjteményt hoztunk létre. Az izolátumok morfológiai azonosítása nem minden esetben vezetett eredményre. A molekuláris azonosítást a riboszomális

Nutrition Status of Trees on Spoil Heaps After Coal Mining Can Be Inferred From Seasonal Dynamics of Foliar Nutrient Concentrations

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT A stable vegetation cover on given habitat conditions can be one of the possible requirements for post‐mining sites, as it can prevent erosion and dustiness of these anthropogenic surfaces and bring several practical future benefits, such as biomass production and microclimate improvement.
