Effect of seed priming on germination of relict beautiful vavilov, Vavilovia formosa (Stev.) Al. Fed.

OpenAlex English

Priming of seeds increases uniformly germination rate in cultivated and wild species as well, it also shortens germination and emergence time. Beautiful vavilovia, Vavilovia formasa (Stev.) Al. Fed. is a relict and endangered legume crop which is the closest relatives of the genus Pisum L. In beautiful vavilovia, seed priming has ignored due to insufficient seed production of the plant. In the present report, three seed priming including hydro-priming, glycerol (%1) and potassium chloride (KCl) of 5% were compared to control (no-priming application). Findings have shown that seed priming with glycerol significantly accelerated germination time in beautiful vavilovia. Despite better germination time with hydro-priming after glycerol, hydro-priming had almost similar to control. Germination was stalled off at KCl treatment indicating that beautiful vavilovia could be salt susceptible. Priming with glycerol can be suggested as the fast and reliable germination of seeds of relict beautiful vavilovia.
