Abstract: This study was conducted to test the strength of glue line in wood structures by using some mechanical tests (shear strength test, Dry and wet tensile tests). Two kinds of adhesives (Urea-formaldehyde (UF) and poly-vinyl acetate (PVA) with three types of wood surfaces (Pure Pine, Pure Sycamore and substrate of Pine with Sycamore) and two methods of adhesive curing (Electrical and microwave domestic ovens) were used. It was shown from the study results that wood type had an effect in share tension test, pine wood gave the best results followed by shear tension of sycamore wood and pine with sycamore wood, but there were no significances between the three types of woods. Urea formaldehyde adhesive got the highest shear tension values when compared with PVA adhesive. Solidification by using electrical oven method gave the best values in shear tension as compared with the microwave oven curing method. The results also showed that 1 gm adhesive quantity gave the best results as compared with 0.75 gm and 0.5 gm in shear tension. Concerning the dry and wet tensile tension of the PVA glue line by using electrical oven dry, microwave oven and room temperature solidification methods, the results showed that pine wood had greater dry and wet tensile tension than sycamore wood and pine with sycamore wood. Also, parallel grain direction gave the best values as compared to perpendicular grain direction for both dry and wet tensile tension. The results also showed that the highest dry tensile tension was by using electrical oven solidification method، followed by room temperature method، while solidification by using microwave oven gave the lower tensile tension value. Room temperature solidification method gave the best results in tensile tension after emersion in water for 30 and 60 minute as compared to electrical oven and microwave oven solidification process respectively.

Abstract: Three trees were randomly selected from each age, The trees were felled and one disc 5cm. in thickness were taken from DBH in each selected tree to study the anatomical properties namely; fiber length، fiber diameter, fiber wall thickness, the ratio of double fiber wall thickness to lumen diameter (Runkel ratio) and the ratio of fiber length to its diameter. From each disc a sector was taken from the pith to the bark and divided into three equal parts to study the variation in anatomical properties across the stem.Average fiber length of the young trees (1.03mm), while (1.00mm) for the mature trees.Analysis of variance showed no significant difference between the trees for all the anatomical properties in this study for both ages. Analysis of t test showed that there was no significant difference between the average of fiber length to its diameter، While there is significant difference between fiber wall thickness, fiber lumen diameter and the Runkel ratio.The results did not shows any regular concerning the variation of fiber dimension in the radial direction .It was shown that there is a significant increase in the fiber length for each ages and in the fiber wall thickness and the Runkel rtio for the mature trees. There were an increase from the pith to the middle then not significant increase for the fiber diameter and the Runkel ratio for the young trees but it is significant for the ratio of fiber length to its diameter in the mature trees. There was no significant increase in the fiber diameter and fiber lumen diameter from the pith to the middle then there is a significant increase till the bark and there was a decrease from the pith to the middle then there is no significant increase to the bark of the young trees. We can conclude that the fiber length of the tow ages lies within the fiber lengths ranges used in pulp and paper manufacturing. The average of Runkel ratio of the mature trees also lies within the values required for pulp and paper manufacturing so it maybe more suitable than the young trees. Crystals in chambered fibers، libriform fibers and fibers with dentate end were observed.

It affects most types of durum and bread wheat cultivated in the world, causing losses in grain yield. Given the importance of this strategic crop and the relative lack of studies on this disease in Syria, and genetic resistance, this study aimed to: Evaluate and select durum and bread wheat accessions for resistance to common bunt.Seed of 104 durum and 102 bread wheat genotypes were screened in 2006/07 and 2007/08 seasons, under artificial inoculation using a mixture of teliospores of both T. tritici and T.leavis under field conditions. Significant variations in reaction types were found in infected plants. In the first season, 12 durum and 4 bread wheat genotypes showed resistant reaction (R) to the disease, and 23 durum and 4 bread genotypes reacted moderately resistant (MR). Only 8 tested durum genotypes were resistant in the second season, meanwhile 24 tested durum and 10 bread wheat genotypes proved moderately resistant (MR). The resistant genotypes could be used in breeding programs for increasing resistance of high yielding wheat cultivars.

Abstract: A field experiment was conducted to investigate the influence of Biofertilizer EM1, Nitrogen fertilization and removing the leaf under ear on growth traits, grain yield and its components of corn (Zea mays L.), in two locations for the autumn season 2009. The first location was in Mosul City، while the second was in Salamya 34 Km southern Mosul city. The split- split plot arrangement in Randomized Complete Block Design (R.C.B.D) with three replications was used. The experiment included four levels of Biofertilizer EM1 (0, 0.5, 1, 1.5 cc/Liter), two levels of Nitrogen fertilization (zero, 120Kg N/ha) and two treatments of removing and non removing of leaf under ear . Nitrogen fertilization levels, Biofertilizer EM1 and removing leaf under ear were represented as Main plots, sub plots and sub sub plots respectively. The results indicated that nitrogen fertilization level 120kg N/ha was significantly superior as compared with non nitrogen fertilization in all growth traits: number of days to 75% flowering، stem length, leaf area, leaf area index، leaves and stem dry weight. Grain yield and its components: ear length, number of rows per ear, number of grains per rows، weight of 500 grains، grains yield and harvest index. Grain quality: protein percentage and yield, oil percentage and yield in both locations. Increasing of Biofertilizer EM1 levels caused significant increase in all growth traits, grain yield and its components and grain quality in both locations. Removing the leaf under ear was significantly superior compared with non removing in all growth traits, grain yield and its components and grain quality in both locations.
