The article presents the results of a study of germination and germination of seeds of the plant
Crambe tatarica Sebeòk, a rare, endangered species in the conditions of the Aktobe region.
During the study, the seeds of this plant species were collected during the expedition in two districts of the Aktobe
region: in the village of Akrab of the Khobdinsky district and in the village of Akshatau, also in the chalk mountains of
the Mukashtau district. Morphological features of seeds, fruit quality, germination of fruits and seeds were studied for
the first time in laboratory conditions. According to the results of the conducted studies in three populations of
measuring the morphological forms of fruits and seeds (five and ten) in length and width, long seeds have plants
growing in the Cretaceous highlands of the Mukashtau district, 22.07.20 (1.6 and 1.2 mm, 1.5 and 1.1 mm), and the
lowest indicators were observed in the settlement of Akrab 19.07.20 g of the Khobdinsky district (0.5 mm and 0.3 mm,
0.6 mm and 0.3 mm). The average weight of 1000 seeds and fruits is maximal in the first population – 5.8 – 8.24 g.
(22.07.20 g.), respectively, the lowest weight of seeds – 3.87 - 4.27 g. is typical for the first population (19.07.20 g.).
