Изменчивость Valeriana officinalis и Valeriana exaltata в Беларуси

Abstract

Variability of morphological characters of two diploid valerians: narrow-leaved Valeriana officinalis and broad-leaved Valeriana exaltata has been studied. The differences between these species were found on the following characters: the height of the stem and its thickness at the base, the number of verticils, length and width of the leaf segment, number of teeth and their depth on the top and bottom of the leaf, the average length of hairs along the veins on the underside of leaves and their quantity.
