STUDY OF THE MORPHOLOGICAL AND ANATOMICAL STRUCTURE OF FERULA FOETIDA SEEDS FROM DIFFERENT MANGYSHLAK POPULATIONS

The paper presents the results related to morphological and anatomical characters of Ferula foetida seeds from different geographical origin. Seed samples collected from Tuyesu and Karynzharyk sands, and the surrounding country of the Tynimbay Shoky Upland (Western and Eastern parts). The morphological parameters were determined on the basis of the length and width of the seeds and the weight of 1000 seeds; and anatomical parameters were determined on the basis of the analysis devoted to the structure of the cross section of seeds in their central part.

The maximum values of morphological parameters were revealed in seeds collected in Karynzharyk Sands, and the minimum values are for plants growing in the surrounding country of the East Tynimbay Shoky Upland. The features of the anatomical characters of Ferula foetida seeds were described for the first time. All seed samples, regardless of plant growth, have the same structural plan and parameters of cells and tissues. The maximum sizes (10.19 ± 0.49 mm) of microscopic structures were noted for West Tynimbay Shoky Upland, and the minimum sizes (8.54 ± 0.37 mm) were recorded for ferule populations from East Tynimbay Shoky. The Weight analysis carried out showed that the maximum sizes (0.23 ±0.02), both of individual seeds, and of tissue and conceptacle sites, were identified for plants growing in Karynzharyk Sands, central part solid mass; the minimum values (0.16 ±0.005) were noted for samples collected in Tynimbay Shoky Upland. The morphological and anatomical sizes and weight of the seed material in Ferula foetida populations vary depending on the place of growth, which is explained by the difference in habitat conditions. Promising populations for the selection of seed material with subsequent introduction into the conditions of the Mangyshlak experimental botanical garden are proposed.
