Climate change is a reality of the difficult period we are going through. Plant evolution is generally strongly correlated with variations in temperatures, precipitation, and solar radiation being affected by extreme events. Late frosts influence fruit production, the number of cold hours (perhaps insufficient in recent years), and winter windows in which very high temperatures occur and negatively influence the dormancy of some fruit-bearing species. Paw-paw (Asimina triloba L. Dunal) and jujube (Ziziphus jujuba Mill.) are new fruit species for Romanian areas more resilient to climate change. This paper aims to present the available information on this new fruit species' chilling and heat requirements, focusing on the methods used for their determination. The results reflected the scarcity of research on these fruit species and the necessity to have a methodology with the possibility to extend to new cultivars in different areas.
