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 fl
oor 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.
