The estimation of the modern state arboreal plants dendropark Lugansk State Agrarian University was first given. It set that now 5712 copies trees, bushes and lianas, related to 104 species from 63 genus 29 families, sprout on this territory. Dominant position is occupied by trees - 55.6%, 37.0% lianas 7.4%. conditions Aesculus hippocastanum L., Betula pendula Roth, Populus alba L. nigra are ca...

An alternative way to increase plant productivity through the use of nitrogen fertilizers is to improve the efficiency of nitrogen utilization via genetic engineering. The effects of overexpression of pine glutamine synthetase (GS) gene and nitrogen availability on growth and leaf pigment levels of two Betula species were studied. Untransformed and transgenic plants of downy birch (B. pubescens...
