Study of some Chemical Composition of the fruits of Prunus ursina K.y phenotypes in Westrens of Syria

This study was carried out during 2015to determine some chemical Composition of the fruit of some distribution phenotypes of Prunus ursina in different regions of Westrens of Syria. six natural distribution sites were determined(Duerbsndiana-Alnabeen-Alshohtte- Helata-Btmazah-Wadeheleen), and 35 trees were determined as samples. Fruits were harvested and following parameters were determined: dry matter, total acids (T.A), total soluble solids (T.S.S), and total sugar. Statistical analysis of investigated phenotypes showed that There were differences between dry matter, total soluble solids (T.S.S), and total sugar between two groups. the trees were distributed in two groups (A, B) .The results showed existence of most trees in whole sits, while (J6 and KA6) were distributed in two different sits(Btmazah and Duerbsndiana) .

Study contrast ratio some productive characteristics and essential oil content depending on the different mowing time for common thyme Thymus vulgaris L. grown in Banias from the Syrian coast

The research aims to study the effect of five harvesting wed (vegetative growth, the beginning of open inflorescences flowering, the beginning of flowering, full bloom, and completeness of the vegetative growth at the beginning of the month of September and that of plants that have already cutted), some of the morphological and productivity indicators for common thyme Thymus vulgaris L . Experiment was designed by the complete randomized manner in three replicates. Statistical analysis was performed by Anova test using Genestat and account teams less moral LSD at a significance level of 5%. Results showed superiority date mower fifth morally on the rest of the dates in terms of index number of branches (16.50 branch / plant), productivity of the wet weight (55.00 g / plant), productivity of dry matter (27.08 g / plant), while the superiority of the date of the second mowing morally the rest of the appointments in terms of the percentage of essential oils (size / weight) (2.10%), also reached the top of the plant at the time of his high mowing fourth (21.50 cm). Highlights the importance of the results by identifying the optimal harvesting date to get the most fresh and dry weight of material and the highest percentage of essential oil, and the resulting economic return to the farmer healthy and beneficial to the consumer, with the continued preservation of the existence of the plant and its tender.

Productivity and quality of panicum (Panicum turgidum Forssk) grown naturally at the Eastern Province of Saui Arabia

The present study aimed to evaluate the productinty status of panicum turgidum (Thumam) under the environmental conditions of the eastern province of Kingdom of Saudi Arabia. Forty eight experimental sites (each of 25 m2, i.e. 1*25 m) were randomly selected from three locations (Roads of Riyadh, Ogair and Damam), which represent the micro-environment of thumam. Obtained results showed that the dominated plant species associated with thumam were Eragrostis barrelieri, Haloxylon salicornicum, Leptadenia pyrotechnica, Plantago ovata and Zygophyllum coccineum. The forage production of thumam was 57 kg dry matter/ha. However, the nutrient value of it was relatively low due to the low protein content (4.2 %) and high crude fiber (30.2 %). Moreover, neutral detergent fiber was 62.4 %, acid detergent fiber was 65.4 % and lignin was 11.70 % which indicate low nutritional forage value, compared with traditional forage crops, i.e. Rhodesgrass (Chloris gayana) and Alfalfa ( Medicago sativa). Macronutrient contents (Na, K, Ca and Mg) were in the range of sheep and camel requirements, while P was very low as well as micronutrients (Zn, Cu and Mn).
