Some factors affecting the natural generation of Pinus pinea L. stand in Dahr Kheribat site - Lattakia


Abstract in English

The study was achieved in 2014-2015 at Dahr Khribat stone pine forest, Latakia. to determine the factors affecting the natural regeneration of the stand. The results of climate studies indicated that the region is located in the semi-wet climate floor with a mild winter as the average of rainfall thermal coefficient reached (Q2 = 72.01). The study showed that the low productivity of cones (20 kg con / tree) was one of the limiting factors of natural regeneration. The trees high density (462 tree / ha), led to a decrease in tree diameter at breast level (30 cm) and low coronary size (320.2 m3). Seed germination was not affected by illumination periods, while salinity levels led to a significant decrease in germination from 90% at control to 19% at 0.5 mol / l. All of one year old sapling or seedling were dead during summer months, while more than 90% of two years old cultivated sapling, survived in all treatments, but no significant differences among them.
