    Opis:
    The effect of gibberellic acid (GA3), forchlorfenuron (CPPU), and abscisic acid (ABA) on the parameters of yield of ‘Flame Seedless’ grapes was investigated. The clusters of 8-year-old grapevines were sprayed with solutions: GA3 at 25 mg·dm-3, CPPU at 10 mg·dm-3, and ABA at 300 mg·dm-3, alone or in combinations. GA3 and CPPU treatment increased yield, cluster weight and length, berry weight and diameter, as well as fruit firmness, but reduced the total soluble solids (TSS) and intensity of berry color. Anthocyanin content of berries treated with GA3 and CPPU increased significantly by ABA treatment. Shelf life was increased by GA3 and CPPU treatments, as they decreased the percentage of weight loss, shattering, and unmarketable berries after storing at 20 °C for 7 days. Thus, it can be concluded that the combined use of GA3, CPPU, and ABA may be an efficient practice for fruit enlargement, coloration, and keeping quality in ‘Flame Seedless’ grape.

    Opis:
    A pot experiment was carried out under greenhouse conditions to study the impact of the evaluated treatments namely abamectin, azadirachtin 0.15%, azadirachtin 0.03%, Bacillus subtilis, Pseudomonas fluorescens, Paecilomyces lilacinus and oxamyl against root-knot nematode (Meloidogyne incognita) on the tomato plants cv. Super strain B. The results indicated that the most of the tested treatments obviously reduced root galls and remarkably increase tomato plant growth characters significantly and egg masses on root system, as well as, juvenile's numbers in the soil. P. lilacinus was the most effective treatment on both galls and egg masses achieving 88.23 and 76.94% reduction, respectively. While, less effective treatment was P. fluorescens achieving 57.53% galls reduction. Azadirachtin 0.03% was the least effective treatment giving 40.37% reduction of egg masses. The superior treatment that suppressed nematode populations was oxamyl recording (88.90%) followed by abamectin (78.69%) reduction. Moreover, azadirachtin 0.15% was the least effective treatment which recorded 60.15% reduction. On the other hand, plants free nematode recorded the highest plant parameters for shoot system length, fresh shoot weight, dry shoot weight and root system length with values of 24.15, 107.53, 211.59 and 46.17% increase, respectively. Azadirachtin 0.15% was the least effective treatment on shoot system length and fresh and dry shoot weight. While, oxamyl recorded the least increase in root system length estimated by 18.47%. B. subtilis recorded the highest increase in fresh root weight followed by P. fluorescens with value of 125.75 and 86.57%, consecutively. Vise versa, P. fluorescens was the superior treatment to increase the dry root weight by 68.14% followed by B. subtilis which recorded 35.40%. The least effective treatment in improving fresh root weight was azadirachtin 0.15% which recorded 54.85% increase. Regarding to dry shoot weight P. lilacinus and azadirachtin 0.15% were the least effective treatments with values of 8.85 and 2.66% reduction, respectively.

    Opis:
    Application of assisted reproductive technology in camelidea, such as artificial insemination (AI) and embryo transfer, has been slow in comparison to that for other livestock species. In Egypt, there are few attempts to establish in vitro maturation (IVM) and fertilization (IVF) techniques in dromedary camel. The present study was carried out to produce Sudanese camel embryos using in vitro matured oocytes and epididymal spermatozoa. Dromedary camel ovaries were collected from abattoirs and then, the oocytes were aspirated from all the visible follicles on the ovarian surface (~2-8 mm in a diameter). Meanwhile, Fetal Dromedary Camel Serum (FDCS) was obtained from camel fetuses after slaughtering. Thereafter, only Cumulus Oocyte Complexes (COCs) were matured in vitro in the Tissue Culture Medium (TCM-199) complemented with 10% FDCS. Spermatozoa required for in vitro fertilization were collected from testes (epididymal cauda) of the slaughtered camel bulls. The results clearly showed that the maturation rate of oocytes at metaphase II was about 59.5% while the fertilization rate was around 70.4%. Intriguingly, the embryo rates determined were 13.1%, in 2-cell; 0.0%, in 4-cell; 34.7%, in 8-16% cell; 39.1%, in morula and 13.1% in a blastocyst stage. This study represented a successful in vitro production of Sudanese dromedary camel embryos from epididymal sperm cells and in vitro matured oocytes recovered from slaughtered camels.

    Opis:
    The investigation of surface modification of Egyptian calcium carbonate via polymers was achieved with simultaneous ultra-fine grinding. Attrition mill and planetary mill were used for wet and dry grinding, respectively. The parameters affecting the grinding were studied such as ball number, speed and grinding time. The rheological characteristics of the aqueous calcium carbonate suspensions were studied in the presence of different types of polymers. The results indicated that the mechanical force could clearly affect the modification characteristics of calcium carbonate due to its mechanochemical effects. The viscosity of calcium carbonate suspension depends on the volume percentage or weight percentage. The dispersing agent increases the solid concentration for a given particle fineness.
