Peculiarities of morphometric and anatomical characteristics of Scots pine (Pinus sylvestris L.) in the stand affected by annosum root rot

Abstract
Morphological, anatomical and biometric features of Scots pine (Pinus sylvestris L.) were investigated for the trees which are in annosum root rot (Heterobasidion annosum (Fr.) Bref.) focus and are distinct in health condition (“health”, “stable” and “sick” trees). Taxation indicators as well as the colour, shape and size of cones and seeds were studied; needles parameters were measured and its anatomy (number of resin channels and their location) was explored. “Stable” individuals were significantly different from the “sick” ones by stem height, biometric sizes of generative organs, morphological and anatomical features of needles. Variability of most studied biometric features is modification one, so using them to assess the stability of the trees in stands cannot be effective. There was no correlation between generative organs’ color and resistance of the trees, but in the group of “stable” trees, individuals with hooked apophysises of cones and seed scales and with a larger number of resin canals in the needles dominate. Control trees and the individuals characterized by high resistance have the similar biometric parameters and a higher degree of parameters variability than “sick” ones do.
