CHANGE ANATOMICAL PARAMETERS OF NEEDLES PINUS ELDARICA TEN., GROWING IN ROADSIDE PLANTATIONS KHUJAND CITY
Studied anatomical parameters of needles Pinus eldarica Ten., growing in roadside plantings Khujand. As a general trend of changes in anatomical characteristics of all roadside plantings should be noted lengthening of the needles, increasing its surface area, reducing the diameter of the resin ducts and the height of the cuticle, the extent of these changes depends on the location of growth. The greatest number of significant changes in the anatomical nature of the adaptive parameters of needles of pine was found in the right-bank part of the city - on the street 50 years of the Soviet Union, characterized by a high intensity of freight transport and the close proximity of ore mining enterprises. In Pinus eldarica Ten. on the street 50 years of the Soviet Union in comparison with the control was significantly lengthened needles, increasing the area of its cross section, the area of the central cylinder and mesophyll.
