Comparative Study of the Emergence and Growth of Young Seedlings of Five Varieties of Pistachio (Pistacia Vera L.) of Syrian Origins

The present work is to study the emergence and growth of seedlings of five pistachio varieties that are: Batouri, Achouri, Neb-Djemel, Adjmi and Bayadhi. The study was conducted in a greenhouse temperature and photoperiod were controlled. The seeds are germinated in pots filled with peat without going through the damp cold stratification at a temperature of 4ºC. The results obtained showed that growth parameters (length and diameter of the plants) revealed significant tests while other parameters (emergence rate, root length and number of leaves per plant) had showed no significant tests. About the number of emerged plants per day, variety Achouri comes first while the variety Neb-Djemel comes last. About the number of emerged plants per day, variety Achouri comes first while the variety Neb-Djemel comes last. For the evolution of growth in height, it is on average 2cm per week until two months after emergence; then it becomes 0.37 and 0.88cm for the final week of growth.
