تمّت دراسة التنوع المورفولوجي لدى أربعة أنواع من الرغل (القطف)، اثنان منهما مُدخل و هما الرغل الأمريكي و الرغل الكاليفورني، و اثنان منتشران بشكلٍ طبيعي في سورية و هما الرغل السوري و الرغل الملحي. أظهرت النتائج أنّ النمط الحياتي، دورة الحياة، لون النباتات، شكل القنابات الثمريّة و نمط التحامها، رائحة النبات، لون البذور، و شكل الأوراق و نمط توضعها، من أكثر الصفات المورفولوجيّة التي ميّزت الأنواع المدروسة بعضها عن بعض، و التي يمكن اعتمادها كمعايير تصنيفية للتمييز بين الأنواع المدروسة التابعة لجنس الرغل ضمن رقعة توزّعها الطبيعيّة، التي تعتبر الموئل الطبيعي لهذا النبات المهم. و قد أمكن وضع مفتاح تصنيفي للأنواع المدروسة بالاعتماد على الصفات المورفولوجية.
Atriplex is one of good adaptive plants to the Characteristics of drought fragile environments, and it has high ability to tolerate many ecological stresses such as drought and high temperature and salinity. The plant is characterized by its huge economic values because it has many uses, it’s one of the high digestibility grazing plants and it is grazing by camels, goats and sheep all the year, some of them have medicinally uses in repairing the increasing of blood sugar, the freshness parts of some species use in preparing salads, even they have cook using, and leaves usually have a salty taste even the plant grow in none salinity soils. The morphological variety of four species of Atriplex were studying, two of them are introduced (A. canescens, A. polycarpa) and two have natural spreading in Syria (A. leucoclada, A. halimus). The results indicated that biological type, life duration, plants color, fruit bracts shape and fused of fruit bracts, plant smell, seed color, leaves shape and phyllotaxy are considered the most morphological characters which show important morphological differences among the studying species. These can be considered among classification standards to help distinguish the studying species of Atriplex genus under their natural spreading land, which consider the natural habitat for this important plant. Based on studied morphological characters, an identification key for the studying species is provided.

This investigation was carried out at the Laboratory of Biotechnology at
General Commission for Scientific Agricultural Research (GCSAR), during the
season 2010-2011. The aim of this research was to study the genetic diversity
among twenty individ
ual plants of seven species and to determine the degree of
genetic similarity using the technique ISSR (Inter Simple Sequence Repeats)
and 10 primers were used for this purpose. All primers proved their
effectiveness in showing polymorphism between the studied species, primers
gave a total 195 allele with a polymorphic percentage 100%. The number of
bands for each primer varied from a minimum of 12 bands for the primer
(ISSR-4) to a maximum of 27 bands for the primer (ISSR-862) in an average of
19.5 bands for each primer, cluster analysis and Dendrogram showed the
highest degree of genetic similarity between accession A.leucoclada1 and
A.leucoclada2 (0.64), while it was low between species A.leucoclada3 and
A.glauca2 (0.10). Results showed vast genetic diversity among the studied
species.
Taxonomic study confirmed of genus Ornithogalum L. (Star of Bethlehem)
recording 4 spices belonging to him are: O.narbonense L., O.montanum Cyr.,
O.umbellatum L., O.ulophyllum Hand.. for the first time in the Jableh region, The
morphology of the d
atabase was put included (Habit - bulbs - bulbest surrounding Balbs -
leaves- presence of the white line on adaxial of the leaf - the green line on abaxial of the
tepal - stamens - pistil - fruits - seeds - with type and dimensions of pollens and definition
the stomatal type) and linked these character by using Statistica for Dendrogram which
showed the presence of 3 clusters, cluster common of two spices O.narbonense,
O.ulophyllum, While an alone all of two spices O.umbellatum O.montanum, cluster of its
own, and put a taxonomic key to distinguish between studied species.
Wadi Huraira Basin is considered one of the left boundary basins to
Barada at Kafer Al-Awameed. It extends to an estimated area north-east and
south-west about 56 square kilometers. It is bounded Bisan Basin and Madaya
Mountains Basin from the fro
m the north, and from the east both of Bisan and
Wadi Mahadi Basins; whereas the later shares forming the southern boundaries
with both of Abou Salem and Wadi Alawaz; whereas, Barada River forms the
western boundary of Wadi Huraira Basin.
The experiment carried out in the agricultural Center (Boqa) of Tishreen University,
in the province of Lattakia, during the agricultural season (2014), in order to study the
effect of different types (cattle, sheep, poultry) and rates (0, 15.30 to
n/ha) of the compost
on durum wheat (Doma1). It farmed on (11.23.2014), according to complete system of
randomized sectors (27 bis).The compost was added within the lines of Agriculture
(10/06/2014). The results showed a response to the average of all the studied traits (plant
density (plant/m2), plant height (cm), the length of awn (cm), grains/spike weight (g), the
weight of 1000 grains (g)) positively organic fertilizing. While no significant differences
were recorded in the averages of the traits studied (plant density (plant/m2), plant height
(cm), the length of awn (cm), grains/spike weight (g), 1000 grains weight (g)) under the
manure type. In the case of overlap between the type and the rate of organic manure, it has
recorded a significant and high differences between the treatments. The treatment (30
ton/ha-1 poultry) was the most influential of all the studied traits. It gave the following
results: plant density (331.70 plants/m2), plant height (95.85cm), the length of awn (16.24
cm), grains/spike weight (1.66 g), 1000 grains weight (49.57 g).
This research was carried out through the 201-2011 and 201-/2012 seasons
on 26-year-old trees of AL– Ashouri Pistachio cultivar grown in clay soil, in a
private orchard in Souran region (Hama province). Four types of organic green
fertilizers (Len
tils, Vetch, equal mixture from Lentils and Vetch and mix of
these legumes with barley), in addition to the control, to study their effects on
some quantitative and qualitative characteristics of pistachio nut. Results
showed that the use of green fertilizers caused significant increase in studied
indicators and the best treatment was mix of legumes with barley (45% Lentils,
45% vetch, 10% Barley), which achieved the highest significant values، where
average of weight of the 100 nuts was 107.45 g during the two seasons, the
average of weight of the 100 kernel was 67.08 g, average of length of shell was
20.85mm and an annual yield was 32 kg/ tree, compared with control, which
achieved 87.50g, 40.25g, 18.08 mm and 16.75 kg, respectively.
