Abstract

The viability of some Apocynaceae seeds depending on the duration of storage under conditions of low temperature was studied. Extracted embryos from the seeds of Pachypodium lamerei Drake and Adenium obesum (Forssk.) Roem. et Schult with different storage history were analyzed. Embryos were stained by acidic fuchsine what allows identification of viable and destructed cells. Destructed cells were stained much more intensively, while viable cells remained unstained. Observed results showed dependence of viability of P. lamerei and A. obesum seeds from term of storage. It was obtained that the seeds of investigated succulent species, just like in many other tropical plants, rapidly lost their viability and should be described as microbiotic.
