Populations and four forest cultures were characterized by a low level of heterozygosity (Ho=0,182-0,205), and it was significantly higher (Ho=0,245-0,300) in another two ones. Genetic polymorphism of P.sylvestris stands, affected by H.annosum, was lower compared to the natural populations, immune to the pathogenic agent (A=2,22-2,67, Pg =2,83-3,11). The effect of air pollutants results in a lower genetic polymorphism in P.sylvestris seed progenies. Coefficient of narrowing (Cn) and pulling-out (Cp), characterizing the form of the seed scale upper part, are characterized by an average level of this feature variation in Picea abies L. from the Ukrainian Polesiye. High potential seed productivity was revealed in P.pungens irrespectively of the distance of its location from metallurgical plants. Scale form index as a possiblephenomarker can be used for studying of P.abies intraspecific variation in the Ukrainian Carpathians. Product Description popup.authors popup.nrat_date 2020-04-02 Close
