Abstract: 

Five wheat mutants (T. aestivum L.) were induced from the Sonalika variety in addition to the untreated variety which was used as a control. The mutants were planted in the Shibam region-Yemen- in the period 18-22 / 6 of 2013 and 2014 under irrigation conditions. Seeds were exposed to irradiation with 250 GY in the Seibersdorf laboratory in Vienna. Evaluation and selection were performed in mutant populations. Results showed that a significant difference between mutants each other in one hand and between mutants and the control in the other hand for grain yield, 1000 kernel weight, length of the spike, number of grains per spike, number of days to heading and maturity, at the same time, a variation was observed in the severity of disease within the planted mutants. A positive correlation was found between yield, spike length and number of grains per spike, while negative correlation between yield, number of days to flowering and maturity, whereas a positive correlation was noticed between spike length and number of grains per spike. Weight of 1000 kernel weight was negatively correlated with the length of spike and number of grains per spike, and the grain yield was positively correlated with the level of resistance of mutant to yellow rust disease. The Erra-008-Sw-4-17 mutant was the highest in the number of grains per spike (47 grain), thousand kernel weight (45gm) and attained the highest yield 3940 kg /ha. accompanied with more resistance to yellow rust disease 7MR, followed by the Erra-008–11-40 and Erra-008-Sw-17-68 mutants in terms of average yield, number of seeds per spike, thousand kernel weight, and severity of disease which were 23MS and 23MS respectively. The untreated variety was the lowest in yield, a number of grains per spike, and thousand kernel weight registered 2795 kg/ ha, 38 kernels, and 38 gm, respectively. The highest incidence of yellow rust disease was recorded 30 S for untreated control.

Abstract: 

The study was conducted during the 2019-2020 season at the Scientific Agricultural Research Center in Lattakia, the aim is to determine the best storage method for pollen grains of two citrus rootstocks, sour orange, and Cleopatra mandarine, and test their vitality and ability to germinate for use in hybridization programs throughout the flowering season. The flower buds were picked in the balloon stage and divided into two parts. flower buds and anthers, three storage methods were tested, 4°C, -20°C, and for three periods of 7, 15 and 30 days, then viability and germination tests were conducted in each storage stage, Germination was studied laboratory temperatures (20 ± 2) C, and incubator temperature (24 ± 2) C. and on three culture media, distilled water, sucrose solution 15%, sucrose solution 30%, The result was that pollen gives the highest percentage of germination immediately after picking and the best way to store pollen is to store pollen at low temperature, the method of storing the anthers was significantly superior to storing the buds at the cold temperature, the temperature of-20°C was superior to 4 °C, and the dye gave an idea of the vitality of the pollen, but did not express its ability to germinate.

Abstract: 

   This research was conducted in the Al-Ghab area to study the effect of mother corm size on the growth of a saffron plant, stigma yield, and production of new daughter corms during two growing seasons 2018 and 2019. Three different sizes of diameter corns (3-3.5 ±0.25 Cm, 2-2.5 ±0.25 Cm, and 1-1.5 ±0.25 cm) were tested and the experiment was carried out as a randomized complete block design with three replications. Results showed that mother corm size has a significant effect on some vegetative growth parameters and stigma yield. Both the number of shoots and leaves/corm were significantly higher in the large corms with a diameter (3-3.5 ±0.25 Cm) compared with those small with a diameter (1-1.5 ±0.25 Cm). In contrast, no significant differences were found in the leaf length between the large and small corms. Significant differences were found in the number of flowers/corm and length and dry weight of stigma between the large mother corms and both medium and small corms. A positive correlation has been shown between the size of the mother corm planted and the number, diameter, and weight of the daughter corms produced.

Keywords: saffron, corms size, stigma productivity, reproduction coefficient.

Abstract: 

The research was carried out in two successive seasons in private Citrus orchard to study the effect of different sources of organic fertilizers and spraying with citric acid on some characteristics of vegetative growth and the content of leaves of total chlorophyll and iron element of Clementine mandarin trees grafted on Sour Orange and planted in calcareous soil, and the age of trees 17 years planted at a distance 5 m. The following treatments were used: mineral fertilizer, Compost(organic fertilizer of plant origin) Poultry manure and Cow manure(organic fertilizer of animal origin), Humic compounds. The added quantities were determined on the basis of the standardization of the effective nitrogen ratio(1000 g/effective N/tree).Spraying with Citric acid at a concentration of (1g/L) was used. the results showed the superiority of treatments mineral fertilization and poultry manure in the percentage increase of tree canopy volume(20.92- 20.63)% compared to the other studied treatments while poultry manure treatment superior in the average leaf area (24.26 cm²). treatments of poultry manure and mineral fertilization (control) were recorded the hights content of dry matter in leaf(42.25-42.17%) respectively.as an average for both seasons. And for the leaves content of total chlorophyll and iron element, the treatment of poultry manure in both indicators was superior compared to the studied fertilization treatments as an average for both seasons (2.123 mg/g fresh weight-113.1 ppm) respectively. with regard to spraying with citric acid, the results indicated that the treatments sprayed with the acid were significantly superior to treatments that were not treated with the acid in most of the studied indicators.

Abstract:

This experiment was used in the experiments unit of the College of Agriculture and Veterinary Medicine – Dhamar University to use the addition of yeast to broiler diets, 135 chicks of one-day-old sexed Ross strain, and a random treatment using the complete random design, and each treatment contained three replicates of 15 chicks for each replicae , where T1 was the control treatment and the treatments T2, T3 with the addition of yeast at 0.5%, 1% respectively. The experimental birds were given free feed and water and the live weight, consumed feed and feed conversion factor were measured While there were no significant differences between the control and the first treatment. The results of the experiment showed that the live weight (gm) was significantly (P ≥ 0.05) higher in the treatment fed on diets containing 0.5% yeast than in the control treatment, while there were no significant differences between the control treatment and the treatment fed on diets containing 1% yeast. The feed consumed (gm) did not show any significant differences (P ≥ 0.05) between the treatments, but the control treatment had more feed consumption than the treatments to which yeast was added, and this was reflected in the feed conversion efficiency (gm for feed/gm of meat), which was significantly better (gm). P ≥ 0.05) for chickens fed on diets containing 1% yeast than the rest of the treatments, which amounted to 1.79 gm feed / g meat: It is concluded from the study that the addition of dry yeast to the diets of the broiler houses led to an improvement in the production performance compared to the control, especially at the level of 0.5% dry yeast without harmful effects on the chicks.
