Abstract: 

The study was conducted during 2023-2024 after selecting three Latakia governorate locations (Sharifa, Kefriyah , Slunfah) on three environmental  phenotypes belonging to Myrtus communis L the study showed significant differences in the fruit dimensions where the phenotype(A)  that belonging to Slunfah area had the smallest  black fruits, phenotype (B)  of Kefriyah region had medium fruits,  in Sharifa region, the fruits of phenotype (C)  were greater than the previous two phenotypes which reached the size of the fruit (0 .37cm³)  The study showed that the phenotype (A) exceeded the average height of the shrub estimated at 295 cm. The phenotype(C) also exceeded the in the dimensions of the leaf and the area and thickness, as well as exceeding the dimensions and weight of the fruit and the number of seeds inside the fruit in highest amount of chlorophyll a on the other hand the highest amount of carotinoids was found in the phenotype (B) which reflects its good productivity, while the highest amount of carotenoids was found within model B. The soil analysis showed that myrtle grow in low salinity soils; the results of the study demonstrate the influence of environmental factors on the form and physiology of the plant.

Keywords: Myrtus communis .L, phenotypes , chlorophyll pigment, salinity.
