The site was planted between 1960-1962 year with area size of 33 ha. The plots were
systematically sampled with area size of 400 m2. The distance between plots was 100 m.
Results showed that: trees number per hectare (N), stand average diameter (db
h) and
height (H), basal area (G), productivity (V) and average annual growth (A.A.G) were: 237
tree/ha, 34.68 cm, 12 m, 21.91 m2/ha, 137.51 m3/ha and 2.64 m3/ha/year ; respectively.
Stand height curve was developed with coefficient of determination of R2=0.50.
This research aimed to evaluate the growth and productivity of planted Pinus pinea
in pure stands at "DAHR AL SORANI" forest site. The site is about 50 km north east of
Tartous city, which is located in Temperate-Humid Bioclimate Zone.
Results sho
wed that the stands were not equivalent in growth indicators; this was due
to many factors affecting growth like site characteristics and trees density…etc. In spite of
the mediocre values of form factor, the volume and mean of annual increment was not
influenced.
Results revealed that the mean values of tree density was 851 trees/ha and ranged
between 350 - 1975 trees/ha, woody volume was averaged at 116.337 m3/ha and
ranged between 51.6519 - 215.3635 m3/ha; annual increment had also an average of 4.4548
m3/ha/year and ranged between 1.9866 - 7.9764 m3/ha/year.
The study showed a high straightness of pine. Pinus pinea trees had very rarely
forked boles.
This research aimed to determine the relationship between diameter and
size of Pinus trees available in 4 different regions in Swieda province. Breast
height diameter and height of tree were measured for more than 500 Pinus
Pinea trees. The relati
onship between diameter and size was studied, and a
model of diameter and size was developed as a polynomial model .
