The research was conducted during the agricultural seasons 2016,2017 m in the Syrian
coast in Tartous governorate, the village of Beit Sheikh Yunus. To study the effect of
organic and chemical fertilization on some productive traits (number of flow
er/plant, fruit
weight /plant, weight of 1000 fruit gr, fruit yield Kg/h, harvest index%) of Coriander plant.
In this research, the
antioxidant capacity(DPPH method), and total phenolic content (assayed
by Folin-Ciocalteu method), ,flavonoids, anthocyanins (pH differential
method) and ascorbic acids(2,6-dichlorophenol indophenol) in three fruit
tissues (
peel, pulp and whole fruit), of four apple cultivars commonly in
Syria(Red Delicious, Rome Beauty, Starking Delicious, Golden
Delicious), were studied.
Biological tests were study the pathogenicity of four
local isolates of Beauveria bassiana (Bals) orginated
from, Latakia , Homs ,ICARDA Jableh on third larval age of Bactrocera oleae.
The purpose of this present research isto evaluate two types of mucilage from two
types of jujubefruits: Z.jujube and z. Lotus, and to analyze the physicochemical and
functional properties of this mucilage.
The extraction process for both types we
re performed under the same conditions of
temperature, mixing ratio and proportion of the solvent used in the deposition process.
The yield of mucilage were extracted from Z .jujube is being 5.8 g mucilage/100g
dry weight, while the yield of Z. lotus is being to 25.23 g mucilage/100g dry weight
The values of pH, Refractive index, Hausnerindex, Compressibility index and
Swelling index for Z. jujube mucilage were: (6.32, 1.3348, 1.048, 4.68, 4.28) respectively
.While those values for Z. lotus mucilage were: (6.32, 1.3360, 1.162, 13.41, 5.42)
respectively. The specific gravity value for 1%solutionof Z. jujube mucilage were 1.0021
g/cm3while for Z. lotus mucilage: 1.0025g/cm3. The values of theBulk density and Tap
density for mucilage powder for Z. jujube ( 0.41- 0.43)g/cm3respectively, and for Z. lotus(
0.43- 0.50)g/cm3respectively.
As for the functional characteristics of thestudied mucilage, the values of water
holding capacity, viscosityand oil holding capacity were: 14.6g water/g dry mucilage, 1.19
centipoise, 2.52g oil/g dry mucilage and emulsification capacity 50% for Z. jujube. While
it was higher in the Z .lotus mucilage 34g water/g dry mucilage,1.23 centipoise,3.22 g oil/g
dry mucilage and emulsification capacity 51.6% .
These results indicate that the mucilage extracted from both mentioned types of
jujube can be used as stabilizer in the field of food industry.
Almond seed wasp Eurytoma amygdali . End is a serious pest on
almond orchards which causes an economic losses in production.
This study was carried out for the morphological description of the
male stages of this pest (larva, pupa and adult) using
stereomicroscope and Scanning Electron Microscope.

This study was carried out on a 17 years Vineyard (Helwani,
Betamooni. Cvs) when the study started. Two deficit irrigation
treatments were studied (%88, 60%), in addition to the control (full irrigation), and each treatment included three replicati
ons. Drip irrigation technique was applied (one irrigation line for each tree line, and eight drippers for each tree). Fruit yield and sugar
percentage were observed under different water treatments.
