There have been studied the phenology and morphological features of the generative organs of Adenium obesum (Forssk.) Roem. & Schult. under the introduction conditions to identify the factors which hamper the artificial cross-pollination and production of viable seeds. It has been found that the budding of plants lasts nearly 90 days, flowering – 30–35 days, fruit ripening – 110–120 days. The flowering of one flower lasts for 5 days, but the pollination is possible only in the first two days, because the link between a flower style and carpers is broken further. Moreover, the high pollen fertility is observed within 3–4 days of blooming. At artificial pollination, mature fruits produce (80 ± 30) seeds. The germination of freshly harvested seeds is 96 %. The procedures at artificial pollination of flowers of A. obesum have been proposed.
