It was found that CEM2 significantly exceeded compared to wild and cultivated types in the average weight of the fruit, and the average weight of the seed, and pulp percentage, and productivity per tree (0.5 g, 0.1 g, 56%, 41kg \/tree)respectively.<\/p>\n The results of cluster analysis\u00a0<\/strong>depending on 12 morphological characteristics showed that the studied types divided into 3 groups: the first group included the types \u00a0\u00a0\u00a0\u00a0\u00a0\u00a0(WREw11<\/strong>\u060c <\/strong>WREs1<\/strong>\u060c<\/strong>WLSr7<\/strong>(where the relationship between the types(WREw11,WREs1)<\/strong>was clearly appeared.The second group included the types )WAK3,CHG5,WLSe1, CHG9,CHG1, CET6, CHG2, WSD4,CEM2,CEM1<\/strong>(<\/strong>, where the relationship between the types\u00a0CEM2\u00a0<\/strong>and\u00a0CEM1<\/strong> was clearly appeared. The results showed the positive impact of stratification on increasing the seed germination in laboratory, and field, speed of germination, homogeneity, and the growth of plants, which was more significant in the period 120 days than in the periods 90 and 100 days.<\/p>\n The results have shown the significant influence of the time of taking the cuttings<\/strong>(semi-woody), and the concentration of\u00a0IBA\u00a0<\/strong>on the percentage of rooting, number of roots, and their length, where the date (15\/10) showed best results than date (15\/8) and the superiority of WSD4 compared to the rest of types(73.33%, 5.75 root\/cutting, 4.48cm), respectively. On the other hand the grafting<\/strong> by T budding(March date) gave the highest success rate, and the best growth of scion compared to(July date)(69.23%, 44.19cm), respectively, and the superiority of CEM2in success rate, and the scion length (69.83%, 41.92cm), respectively.<\/p>\n The results of the effect of\u00a0deficient irrigation<\/strong> on the studied types, by applying four levels(80, 60, 40.30%) of the field capacity, have revealed the negative impact of lack of irrigation water on plant growth, and it was noticed that the effect was higher with increased water stress,and showed that\u00a0WREs1<\/strong>, and\u00a0WREw11\u00a0<\/strong>were more tolerant towater stress. All types survived despite the increase in water stress up to 30% of field capacity, which allowing\u00a0 to cultivate them in the marginal areas.<\/p>\n Keywords:\u00a0<\/strong>Mahaleb,\u00a0Prunus mahaleb <\/em>L., types, survey, morphological characterization, sexwal propagation, vegetative propagation, water stress.<\/p>\n","protected":false},"excerpt":{"rendered":" Mahasen Tawaklna General Commission for Scientific Agriculture Research, Administration of\u00a0Horticulture Faculty of Agriculture, Aleppo University. 2012 Abstract This research was conducted during theperiod 2009-2011 in order to survey and evaluate some types of Mahaleb (Prunus mahaleb L.)in ten sites belong to Syrian governorates represent the most important areas of wild and cultivated Mahaleb’s trees which … Continue reading Survey and Morphological Characterization of Some Wild and Cultivated Types of Prunus mahaleb L. in Syria and their Availability of Drought Resistance<\/span>
