THE QUESTIONS OF THE VARIABILITY OF THE MORPHOMETRIC SIGNS OF <i>HEDYSARUM DAGHESTANICUM</i> RUPR. EX BOISS. WITHIN VARIOUS POPULATIONS IN THE TERRITORY OF THE REPUBLIC OF DAGESTAN
An objective of this research is studying of biological features of a Hedysarum daghestanicum Rupr. ex Boiss., collected in different areas of the Republic of Dagestan and also studying of ecological and morphological features and a polychromism of a corolla from the various populations within this look. Main research techniques: field descriptive methods, rather ecological and morphological stationary methods, ecological and geographical methods. Results of morphological variability of H. daghestanicum Rupr. ex Boiss. are presented in 3 natural populations in the territory of the Republic of Dagestan. The comparative morphometric analysis of 10 exemplars of a H. daghestanicum is carried out, collected during 2015, 2016, 2017 in the territory of various areas of the Republic of Dagestan: Kazbek district near the village of Chirkey, the Botlikh area near the village of Godoberi and Andi. Conclusions: the following regularities are revealed: within population of the village of Godoberi increase in such indexes as quantity of leaves, leaf length, leaf width the scape length, width and length of an unpaired leaflet and also increase in the sizes and thickness of inflorescences is observed. Besides, signs of a polychromism of petals of a corolla were observed that, it is presumably bound to change of ecological conditions of growth of these exemplars of plants.
