Structure and Variability of Correlation Between Morphological Characters of Pentaphylloides fruticosa (Rosaceae) Flowers under Various Conditions of the Mountainous Altay
V. N. Godin
Abstract
A comparative analysis of variability of 18 morphological characters of 300 bisexual flowers of Pentaphylloides fruticosa has been performed in 10 coenopopulations from different ecological-phytocoenotic conditions of the Mountainous Altai. Deterioration of growth conditions leads to an increase both in general variability of most of characters and in the degree of correlation between them. The characters studied have been classified into the groups on the basis of relative variation and coefficient of determination. Calyx and corolla sizes are indicators of variation. It has been established that the greater are changes in correlation between characters, the lower is determination of them. The correlation between characters of the P.fruticosa flower regularly changes under environmental effect.
