In this research, the spectral signature was determined within the wavelength range 350-2500 nm at every 1 nm during all growth stages of some wheat genotypes cultivated in the Arab Center for the Studies of Arid Zones and Dry lands (Sabboura, Damascus countryside, Syria) under the semi arid zones conditions in season 2018. This is to demonstrate the possibility of using them in preeding programs for productivity, as well as finding the relationship between the values of spectral reflectance during the different stages of growth with grain productivity according to mathematical equations based on the values of spectral indices recorded …

This research was conducted at the Scientific Agricultural Research Center (Lattakia/Syria), during the first half of 2015 In order to increase knowledge about the impact of several thermal treatments on some qualitative and quantitative indicators for the growth of shoot and root system of carob (Ceratonia siliqua L.) seedlings. three places were selected with different temperatures degree. The first (Lab, 25±0.5°C ) the second ( Room growth, 20.66±0.5°C ) the third (Open Field, 17.3±0.5°C ). And a private agricultural vessels (Minirhizotron) were used to follow the growth of seedlings roots. The results showed a superiority of Laboratory treatment at …

Comparison Of Some Prunus Ursine K.Y. Genotypes Prevailing In The Western Areas Of Syria In Terms Of Seed Content From Oil And Protein, مقارنة بعض طرز خوخ الدب Prunus Ursina K.Y. المنتشرة في المنطقة الغربية من سورية من حيث محتوى البذور من الزيت والبروتين, Haitham Ismail, Mazen Rajab, Ammar Omran, Safaa Sabbouh

This study was carried out during 2015 (in the Western Areas of Syria), to determine the percentage of protein and oil in the seeds of some distribution phenotypes of Prunus ursina K.Y. in different regions of Westrens of Syria. six natural distribution sites were determined (Duerbsndiana, Alnabeen, Alshohtte, Helata, Btmazah and Wadeheleen), and 35 trees were determined as samples. The fruits were collected and seeded at full maturity phase. Percentage of protein and oil was also determined. Data was taken for ANOVA analysis using the statistical Software Costat. Comparision of averages at significance level 5% was made. The percentage of …

Effect Of Genetic - Environment Interactions For Grain Yield Trait Of Some Genotypes Of Bread Wheat In Syria, تأثير التفاعل البيئي الوراثي لصفة الغلة الحبية في بعض الطرز الوراثية من القمح الطري في سورية, Abdullatef Al- Assaf, Ahmad Shams Al-Dien Shaaban, Abdallah Elyousef, Walid Alouk

The aim of this investigation was to study the effect of GE-interactions of grain yield of bread wheat using the additive main effects and multiplicative interaction (AMMI) model. Twenty-four genotypes of bread wheat were sown at 13 locations for 3 growing seasons (2006/2007, 2007/2008 and 2008/2009). The results showed that main effects due to E, G, and GE interaction were found to be significant (P6 and Douma48114 Results showed the possibility of improvement the selection of bread wheat genotypes by applying AMMI model and GGE Biplot methodology in multi- Environment trails.

This search was conducted during 2014 - 2017 in order to determine the distribution area of Iris unguicularis cretensis in the coastal region of Syria, to evaluate the current situation of its habitats, and to determine the best method to reproduce this plant and evaluate its nutritive value as forage. The distribution area was identified through 12 field trips at various types of parent rocks, expositions, and altitudes along the western versant of the coastal mountains in Syria. The properties of natural habitat was examined in 37 samples distributed along a gradient extending from 300 to 1000 m above sea …
