The results of evaluating the laboratory seed germination of endemic Allochrusa gypsophiloides (Turkestan soap root), depending on storage conditions in combination with gibberellic acid treatment (GA 3 ), are presented. In dry storage, control seeds were characterised by a long after-ripening period and a fluctuating germination behaviour upon removal from storage, with a maximum value of 23%. The sensitivity of seeds to GA 3 during dry storage varied significantly, with two germination peaks at 5-7 months, and 12 months (37.5 and 50% germination, respectively). Cold stratification and cryo-preservation accelerated seed after-ripening, promoted germination synchronisation and increased seed sensitivity to GA 3 . The cold stratification of seeds increased germination four months earlier than during dry storage. GA 3 increased germination from 16.7 and 18.3% for the control to 37.5 and 45% for seeds cryopreserved for 5 and 12 months, respectively. We recommend cryopreserving Turkestan soap root seeds to avoid viability loss and to then germinate the seeds after pretreatment with GA 3 .
