The results of optimization of storage conditions of Portulaca oleracea L. seed material is given in thearticle. It is determined that at low positive temperatures germination of seeds decreases by 3 times by the end of thesecond year of storage. The effect of extremely low temperatures on the viability of Portulaca oleracea’s seed material isstudied; optimal cryopreservation conditions are selected: freezing in plastic cryo tubes, slow thawing at room temperature22 °C. It is studied the influence of cryoprotectors on the degree of viability of Portulaca oleracea’s seed material inliquid nitrogen. The optimal cryoprotector is 15 % sucrose solution.
