ВНУТРИВИДОВАЯ ИЗМЕНЧИВОСТЬ ПОПУЛЯЦИИ ДУБА ПУШИСТОГО В ЗАПОВЕДНИКЕ «ЯГОРЛЫК»

The components of variation of morphological features of the Qercus pubescens Willd. population in the “Yagorlyk” reserve were studied in detail. It was found out that the population is heterogeneous by the main morphological features - the number of leaf lobes, leaf length, leaf petiole length, leaf apex length, characterized by average and significant variation values. It was also found that within the population there are reliable differences between groups (syntaxons) in the number of leaf lobes, lengths of leaf petioles and leaf apices. On the contrary, there is a significant similarity between variants within the population in terms of leaf length, which is insufficient to categorize them into established intraspecific subdivisions in the modern sense.
