MORPHOLOGICAL AND ANATOMIC INVESTIGATION OF SERRATULA CORONATA L. LEAVES

Abstract

The aim of the work. Determining of morphological and anatomical diagnostic signs of leaves of the investigated species.

Materials and Methods. The micronutrients were made from dried leaves fixed in a mixture of alcohol-glycerine-water (1: 1: 1) and studied by conventional methods using the Microscope Item: PB-2610, and the results were photophixized by the Samsung PL50.

Results and Discussion. Rosette and grass root leaves are macropodous, large. In the near root rosette, on average about 6 unpaired leaves with 4–7 pairs of oblong-lanceolate lateral segments. The cormophytic leaves of the median formations are alternate, micropodous or sessile, pinnate-separated or cut, lobed with lace, dark green or reddish shade above. Edge is rigid, unevenly-large-pollen, the spikes on the end with a sharp whitish cartilaginous spine. A fluid skirt is on the veins.

The leaf plate of the stem leaves in the structure is gipostomatic, dorsoventral with a sufficiently differentiated mesophilus. The main veins of the stem pinnatifid leaf, that on the areas between the segments are saddle-shaped. The collateral conductive clusters 9, the larger alternate with smaller ones. There are two small concentric clusters in the lateral spurs.

On micronutrients, from the surface of the cell of the upper epidermis of the leaf plate isodimetric, weakly wavy, the stomata are absent.

The epidermis cells of the lower side of the plate are smaller, with more winding membranes. Stomata are many, round-oval, anomocytic type, surrounded by 3–5 epidermis cells. Somewhere along veins, occasionally between them an epidermis with long 3–5-cell, thin sharp hairs.

Conclusions. The morphologic-anatomical features of the saw-wort were studied, and the main macroscopic and microscopic diagnostic features of the leaves were used, which would be used for standardization of medicinal raw materials - the development of control methods of saw-wort leaves.
