ABSTRACT
In this paper we are following the fundamental morphological, structural and physiological study that would explain the advantages of certain methods for before germinating treatments of the seeds of Paliurus spina-christi Miller. A first stage included a morphological research for completing the description of the fruit of the given species provided in specialized literature. The structural study of the Paliurus seeds was conducted through transversal sections followed by quantitative microscopic analysis (including by stereomicroscope). The seeds stored in layers under various conditions were studied by analyzing the physiological changes that occur as a result of a variation in external factors. For the study of the phytochemical composition of the seeds we took into account the abscisic acid revealed by way of extracting the selective solvents, followed by GC-MS, derived fat acids, and triglycerides, followed by GC-MS as well as the glucides, using also derivational reactions and GC-MS analysis.
