أجري هذا البحث في خمسة مواقع مختلفة الارتفاع عن سطح البحر تمثل الطبقات النبتية المتوسطية للسفوح الغربية لجبال اللاذقية خلال عامي 2010–2011 م على نوع السنديان البلوطي Quercus infectoria Oliv. حيث أظهر هذا البحث وجود فروق معنوية واضحة في تأثير الارتفاع عن سطح البحر في إنبات بذور السنديان البلوطي في جميع المواقع المختلفة من حيث وزن الثمار، و الصفات المتعلقة بطول المجموع الخضري و طول المجموع الجذري للبادرات بعد أربعة أشهر من الإنبات. بينما لم يظهر أي تأثير للارتفاع عن سطح البحر و لم يلاحظ وجود فروق معنوية في الصفات المتعلقة بعدد التفرعات في المجموع الخضري، التفرعات في المجموع الجذري و كذلك بالنسبة لمتوسط عدد أوراق البادرات، بينما كانت المواقع متوافقة من حيث سرعة الإنبات و نسبة الإنبات اليومي إضافة إلى قطر البادرة. يمكن الاستنتاج أنّه توجد تغيرات في النمو الخضري و الجذري للبادرات الناتجة عن الثمار المأخوذة من المواقع المختلفة تبدو و كأنها مؤشر أولي لتأثير الارتفاع عن سطح البحر في بعض خصائص غراس السنديان البلوطي.
This research was carried out in five sites varied in altitude representing Mediterranean vegetation zones of western slopes of Lattakia Mountains during 2010 - 2011 on Quercus infectoria Oliv species. Research shows that significant difference of altitude above sea level has obvious effect on seed germination in different sites. This is noticed in characteristics related to fruit weight, germination rate value sum, and height of vegetal and rooty seedling after four months of germination. Altitude above sea level has no effect on the branchlet number of rooty and vegetal sum height of seedlings as well as mean of leaves number of seedlings. According to germination ratio and daily germination ratio, in addition to seedling diameter, there is harmony among all sites. It can be deduced that there are changes in growth traits of studied seedlings in different sites. This is the primary indication of the impact of the altitude above sea level on seedling traits of Quercus infectoria Oliv.

This research aims to test some equations, used in different regions and forest types,
for assessing the total height of shoots in the oak )Quercuscalliprinos) Maquis forests,
depending on diameter,which enable the estimation of volumes without mea
suringthe
height of these shoots. This is very important to saveefforts, time and moneyinvested by
foresters.
The study included102 samples distributed within the most important oak forests on
the eastern exposition of the coastal mountains. The plots have rectangular shape with 50
shoots at least. The plots vary in shoot density, soil fertility and Maquiage. In each sample
we measured the diameter at a height of 30 cm, the total height of (10-20) shoots of various
diameters (low-medium-dominant).
This study aims to construct a mathematical model to calculate the form factor of
Palestine Oak Maquis grown on the eastern versants of coastal mountains. The form factor
model can help foresters to precisely estimate the volume of tree and forest
stands.
In the year 2014, 129 oak shoots of various ages and sizes, located in natural stands
of different densities and site qualities covering all conditions of region grown on, were
felled.
Diameters at different heights of the felled shoots were measured; shoots volumes
and volumes of equivalent cylinders were calculated, and consequently the values of shoot
form factor were computed. The dataset was randomly split into two parts, 70% (90
shoots) of the data for constructing form factor model and 30% (39 trees) for model
validation.
Several form factor models were developed using the non-linear regression equations
in the statistical program SPSS. Best fit to the data was selected and value of the
coefficient of determination adjusted (R²adj) was about 0.77. The model has been validated
using several statistical methods, the relative bias of the best model ( e%) was ca. -3.6 %,
while the value of model accuracy ) % x m ) was 15%. In order to obtain lower value of
model relative bias and higher value of accuracy, it’s recommended to use a larger
database comprising all distribution areas of oak Maquis in Syria.
This study was conducted to evaluate the effect of pepper (pipiemento
variety), and eggplant (Dara variety) seed's treatment on germination
characteristics, and the impact of eggplant seeds treatment on seedling quality.
The seeds were treated for
24 hours in glass containers, in which the ratio of
seeds to the applied media was 1:5, the concentration of the mineral solution
was 0.1%, while the concentration of each of GA3 and the organic nutrient
solution was 0.01%.
The media were continuously aerated by passing a current of pure oxygen
(O2), at sufficient pressure to homogenously mix the seeds in the media. The
seeds were dried up after 24 hours of treatment to remove the excess moisture.
Seeds were germinated in Petri dishes, and soil-full containers to assess the
germinability, and seed vigor. The eggplant seeds were also sown in peat-moss
containing pots (8 cm indiameter) to study the influence of treatment on
seedling quality.
The results showed that treatment efficiency depends on the nature of the
used media, and crop. In addition, it has been revealed that the aeration of
media enhanced the germination, accelerated the seedling growth, and
improved their quality.
The research aims to study the possibility of using nondirect
leveling to the paths of the earth to find the heights of ground
traverses observatories within the works of the first phase of the
topographic survey rather than direct leveling.
This research aims to studying the plant species diversity in the
oak Maquis at the Eastern versants of the coastal mountains in
Syria, and tries to identify the most important factors affecting this
diversity.
