This study was conducted on Antirrhinum majus plant to investigate the effect of the light selective and colored covers red, yellow and control with spraying by paclobutrazol in three concentrations (0,50 and100 mg.L^-1) on some vegetative growth. The factorial experiment was carried out within Randomized Complete Block design using three replicates with six plants for each replicate. Results indicated that there was a significant decrease in the plant characters grown under the red and yellow polyethylene covers in comparison with the plants grown under the control cover. These characters were the plants height, number of the internodes, number of branches, diameter of the crown area, number of leaves, leaf ar

This study was designed to determine ZmHKT1;5 gene expression  in relatively salt tolerant using four maize genotypes (Alfajr and Almaha  and medium-tolerant ones T1 and T6) within cellular level.  Three salinity levels (2, 8, and 16 ds / m .  Were used immature seeds were surface sterilized and embryos were dissected under full sterilization conditions. Callus was initiated from immature embryos of the above four genotypes on Skoog and Murashige (MS) medium supplemented with the required growth regulators (3 mg/L 2,4-D +0.5 mg/L kinetin) and recultured for three times and transferred to the stress medium containing NaCl.

Cellulose acetate (CA) is a biopolymer produced from fronds of date palm (type teperzal) which were taken from the Iraqi groves. The steps used to produce (CA); pretreatment, bleaching, acetylation and hydrolysis. Organosolv pretreatment method was used to remove high lignin content under mild and severe conditions using NaOH as a catalyst at the concentration (0.03) M. The conditions of Organosolv pretreatment were used: temperature (125 °C mild, 160 °C severe), pretreatment time 90 min, and ethanol: water ratio 40:60 wt/wt. The acetylation of cellulose with acetic acid was used to produce cellulose tri-(CTA) and di-(CDA) acetate for two ways: with treated and untreated fronds. The conditions of acetylation reaction were used:

 Technique of tissue culture for Chia (Salvia hispanica) micropropagation was achieved, this study investigated the impact of various concentrations of plant growth regulators on shoot multiplication and root induction with the Chia’s mature seed as a source explant. The highest percentage of shoot formation (80%), shoots number per explant(3.20) and shoot length(3.26 cm), were recorded on MS medium enriched with BAP(1.0 mgl^-1) after eight weeks of seed culture. The optimal medium for the rhizogenesis was achieved on half strength MS medium fortified with 1.0 mgl^-1 IBA after

This study was aimed to identify the histological and histochemical composition of the Ileum in the Slender-billed gull (Chroicocephalus genei). It was using histological stains and histological chemical techniques. The results showed that the Ileum was relatively long, so it characterized into two parts: an anterior part and a posterior part. The results showed that the mucous layer in the two parts consisted of villi that appeared conical in the anterior region and conical to a triangle in the posterior part, and the villi were more numerous and longer in the anterior part. The villi covered with a simple columnar epithelial tissue containing goblet cells in the two regions, but the goblet cells were significantly more

The present study was conducted in Sulaimani region at two different locations, Kanipanka and Qlyasan during winter season of 2019-2020 to estimate the response of forage yield and some competition indices to the effect of crop pure stands and their mixtures of barley and triticale intercropped with narbon vetch and grass pea with some different patterns. The experiment was designed according to Completely Randomized Block Design with three replications. As the average of both location the maximum green forage yield was produced by pure narbon vetch 32.610 ton ha^-1, while pure barley produce maximum dry forage yield and dry matter % reached 5.506 ton ha^-1 and 8.55% at booting stage respectively, but the crop

The present study was aimed to investigate the possible effects caused by the antibiotic, metronidazole, on the histology of the testis and the morphology of the sperms of mice. To achieve this,  adult male albino Swiss Mice were orally administrated with 0.1 ml (100 mg\ kg ) of the commercially used metronidazole (Flagyl) for 60 consecutive days. The results showed significant decreases (p<0.05) in the mean weight of body and testis in the treated mice as compared to the distilled water-treated control group. The treatment also caused several histopathological changes in the testis which included necrosis, congestion, hemorrhage, edema, germ cell downfall  and rupture in the seminiferous tubules. The tests of the sp

Iraq suffers a severe declining catastrophic in water resources; due to disagreement Share water to the neighboring countries Turkey, Syria and Iran. As well as the water policy in Iraq is unclear, the management of Iraq water have no strategic plan to treat the severe decrease in water sources. In this study, adopted eight climatic stations, are available at Iraqi general meteorological organization. The low clouds data 24 observations per day had been taken, from 1975 to 2005. For this purpose, the researchers determined the distribution of the stations and water amount at the Iraq using (GIS) Technique.  It has found the annual average liquid water content calculated from the Low cloud only is 2585742648
