Ex situ conservation storage potential of Saxifraga cernua (Saxifragaceae) bulbils from alpine species
Abstract In high latitude and alpine environments many plants show an increase in viviparous reproduction in response to harsh environmental conditions. Low or no seed set means that ex situ conservation in the form of seed banking is not a conservation option for such species. We investigated the p...
