A considerable rhizopheric bacteria and mycorrhizae collectively known as plant growth promoting microorganisms (PGPM) have ability to induce acquire resistance in plant against pathogens and to provide benefits to their hosts. Grapevine viruses cause reducing yield and shortening the life span of infected plants in the vineyard. The current study aims to improve quality of Grape fan leaf virus (GFLV) infected grape plants via the soil inoculation with PGPM. Pot experiments were conducted under greenhouse during two seasons 2014/15 and 2015/16 in a Virology Greenhouse, Microbial. Dep. Fac. Agric., Ain Shams Univ. Cairo, Egypt. Grape cv. Flam grafted with GFLV infected stick and cultivated in inoculated soil with rhizopheric PGPB and mycorrhiza (VAM). GFLV was detected in infected leaves by DAS-ELISA. Plant growth parameters and chemical immune acquired resistance were assessment in GFLV infected grape cv. flam. The results were clearly indicated that PGPM inoculation in soil improved of plant growth in the second season (2015/16) compared with first season (2014/2015(. PGPM (Bacillus sp., Pseudomonas sp. and Serratia sp. isolates and VAM) improved quality of GFLV infected grape plants via increased plant growth parameters (leave number, stem diameter, plant length, and phosphorus and potassium components in leaves). PGPM induced acquire resistance in plant against GFLV; it was found that, significant increase of proline and SA contents in GFLV infected grape  leaves compared as healthy ones. The results revealed that chlorophyll a; b and carotenoids were significant decreased while inoculated PGPM in soil showed significant increase compared with healthy control ones. Expressed proteins and resistance enzymes (POD and PPO) of antiviral proteins were significant increase in PGPM application of GFLV infected grape growth related no inoculated PGPM ones. So that the current study recommended that the combination among VAM and PGPB soil inoculation improved quality of GFLV infected grape plant under greenhouse conditions.

Agricultural land holdings went through several changes during the period 1929-2010 due to the changes in the economic orientations and the underpinning economic policies. The study shows that average area of a land holding has declined from 6.13 feddan in 1929 to about 2.19 feddan in 2010. However the average area of a land holding in the old lands has declines from 1.93 feddan in year 2000 to 1.61 feddan in 2010. In contrast the average area of a land holding in the new lands is almost fixed at 9.6-9.7 feddan during the period 2000-2010.   To assess the inequality of the distributions  of land holdings the study estimated the Gini   coefficients of land holdings for several agricultural censuses.  The Gini coefficients were rather high for the years of 1929, 1939 and 1950 with the corresponding values of 0.892, 0.783 and 0.733 respectively. After the 1952 revolution and the issuance of the land reform laws the distributions of land holdings became more equitable as it became evident from the Gini coefficients of 0.597, 0.532 and 0.582 for the years of 1960, 1980 and 1990 respectively.   But apparently there was a reversal in the distribution of agricultural land holdings as the Gini coefficient has shown an upward trend during the period 1990-2010. The Gini coefficient increased from 0.582 in 1990 to 0.628 in year 2000 and then to 0.658 in 2010. This upward trend could be explained by the tendency to concentrate the newly reclaimed agricultural lands in the hands of large farmers and investment companies.

iesel engine, but most of it is operating manually, maintenance and repair centers mostly have used the manually device which depended on the hand of operator to operate it therefore there are inaccuracies in tests. The injector tester device was modified from manual operation to mechanical operation to achieve the uniformity of the injection pressure during the injector test, install of reading, save time and accuracy of testing. Injector tester before the modification was consisted of small fuel tank, pump, pressure gauge, handle pumping and connecting tube. The injector tester device after the modification was consisted of main frame, fuel tank, injection unit, power transmission and measuring table.  From the experiments the fuel consumption was increased with injector tester device before modification than device after modification that with three different injectors due to the regularity of the motion in the mechanical device, but the manual device that is dependent on operator and the irregularity of motion which cause irregularity of pressure. Also, the fuel consumption was decreased with injectors' faults. This is indicating of accuracy reading pressure with the modified devices compared with the device before modified. The results indicated for the important factors which effect on the regularity of injection pressure during the injector testing. The injection pressure for modifying tester device was 175 bar and fuel consumption was 0.73 L/h. The injection pressure  and fuel consumption for tester device before modification were 210 bar and 4.73 L/h respectively. The rate of reducing can be concluded by using the modified tester device for the injection pressure was 1:0.83 and for fuel consumption was 1:0.155 as compared with the manual tester.

The interest in medicinal plants is not only due to the fact that it is a source of food additives, but it is also a major source of medicines. Medical plants contain many important vital ingredients used in the treatment of many diseases. Therefore, medicinal plants are considered a safe source of medical drugs. Many medicinal plants have a significant economic importance to increase their demand. The plant families include many families, such as solanaceae family, which is one of the largest plant families with more than 3000 plant species And the plants of this family contains many important biological components and because of its importance, it was necessary to study and identify these plants by making fingerprinting, detect the molecular genetic markers for this family, study the genetic diversity of these species and determine the relationships between  species of this family by using genetic techniques such as the technique of  Inter simple sequence repeat (ISSR). The results obtained in the five solanaceae species (Lycium shwaii, Hyoscyamus muticus, Solanum nigrum from Northwestern coast, Solanum nigrun from Saint Katherine, and Nicotiana gluca) indicated that, 6 primers were applied. The HB15 primer which gave 12 bands, showed the highest polymorphism 58.33%, and the 49A primer, which gave 6 bands gave a lowest polymrphism 16.66% between the used plants populations, these results mean that ISSR technique is an powerful tool to make genetic diversity assessment for species.

Biological experiments were carried out at Agronomy Seed Lab., Agronomy Dept., Faculty of Agriculture, Ain Shams University and Ain Shams Center For Genetic Engineering and Biotechnology ACGEB, Genetic Dept., Faculty of Agriculture, Ain Shams University during 2016/2017 season. Priming and its duration were investigated whereas different types of priming (hydro-priming, osmopriming and salt-priming) and different periods of each type (short- medium and long periods) were stuied. Newly harvested soybean seeds cultivar (Giza 111) were submitted from Field Crop Institute, Agricultural Research Center (ARC). It was found that type of priming enhanced germination percentage significantly from low performance of 40% to 51%, 68% and 75.5% for hydration, osmopriming and salt priming respectively. Extending exposing period to the longest period gave significantly maximum increment in seed germination. Maximum germination enhancement was achieved when calcium chloride solution was used for the longest period (48 hrs.) giving value of 96.0%. Such increment reached 140% as compared with control.  It was noticeable that increasing soaking period to the longest period examined in this investigation accelerated the rate of germination to a maximum level. Salt priming produced longest soybean seedling shoot when compared with control. Overall, for most results obtained in this trial,   seed primed with CaCl2 showed better perfor mance than those primed with water or PEG solution.  Seedling dry weight revealed a significant effect in a similar manner of seedling length. The longest exposing priming period showed a significant effect on seedling dry weight. Soybeans seeds proteins exposed to priming for all three periods used in this investigation varied from control, whereas number of protein bands on SDS gel increased from 10 bands separated on control pattern to 13, 11 and 12 for hydration treatment at periods of 6, 12 and 24 hrs., respectively. Also number of mono poly-uni. and unique bands varied as well as its intensive dye which reflect that amount of protein formed varied between treatments.  Considering exposing seeds to salt solution of CaCl2 for longest period (48 hrs.) less bands of separated protein were formed on SDS gel. Biological seed quality was assessed by extracting proteins on native polyacrylamide gel electrophoresis, whereas, all priming treatment at application periods caused on increasing in peroxidase activity compared to control (untreated seeds).  It was remarkably that the longest period of expose showed the highest peroxidase activity when compare to control and also for the short and medium exposing periods (6 and 12 hrs.). Also it was noticed that there were a unique diffuse band at the end of the lane, these bands were less intensive in staining color, meaning that their activities is less than those extracted from hydro-primed seeds for short and medium periods (6 and 12 hrs. respectively).  Seed esterase activity bands had two prolonged regions, these bands appeared as a diffuse bands. Esterase activity bands of PAGE gel showed less activity as subjected to all priming types at any period used in this investigation (long, medium and short) when compared to untreated seed (control). It was clear that increasing period of exposing seeds to priming reduced esterase activity since the intensive band diminished in their intensive color.

Fish wealth in Egypt is one of the sources of national agricultural income, as well as a source of safe animal protein sources, which provides food needs internally and develops other industries beside it. Egypt enjoys vast areas of water bodies suitable for production and development of fish resources, which qualify it to be one of the largest producing countries Not only at the regional level, but also at the international level. Fisheries in Egypt occupy vast areas. These sources vary according to their nature. They include the sea, such as the Red and Mediterranean Sea, and lakes such as Manzala, The problem of research is inspite of the fact that Egypt enjoys its position on the Mediterranean Sea and Red Sea and the existence of the Nile River and lakes, the quantity of fish produced does not sufficient for the needs of local consumption, which led to resorting to imports to bridge the food gap. The average  quantity of imports for the same period was estimated at 280.6 thousand tons. The average exports reached about 18.69 thousand tons for the same period. This means that there is a burden on the agricultural and national balance. The objective of the study is to study the development of national consumption And individual of the name The main results were that the relative importance of the value of exported fish during the period (20002015), where the first ranked fresh and salted fish with an engineering average of about 88.4% of the total The value of exports, while in the second place was for other varieties of fish with an average engineering of about 6.7% and the rest of the species (salmon, sardine, herring, tuna and sponge) ranked from third to seventh with an average of about 4.9% The study and the relative importance of the value of imported fish during the period 2000-2015. Toward 73.1% of the total value of imports, while the second place was fish tuna with an average of about 20.9%. The rest of the species (salmon, sardine, herring, crab, shrimp, caviar, anchovy, mackerel, and other varieties) With an average of about 6% of the total value of imports during the study period.

The present work was conducted to study the effect of red palm oil (RPO) and super red palm olien (SRPOL) on the nutritional parameters of rats suffering from hypercholesterolemic. The vitamins (E, A, D and K) and β carotene were determinate by HPLC and indicated that RPO and SRPOL are considered the richest vegetable oils of antioxidant specially α- tocopherol and β carotene. Thirty male rats weighting approximately 210 grams were divided into five groups, each group containing six rats. Group G1 fed on basal diet as a control negative group. Group G2 fed on basal diets containing 2% of cholesterol as a control positive group and the other groups G3, G4 and G5 fed on the same diet used in group G2, yet the corn oil was replaced by RPO in G3 and SRPOL in G4, Meanwhile, group G5 was fed on the same diet used in group G2 and supplemented with a drug contained Lipitor Atorvastatin (20 mg/Kg BW rat daily by stomach tube). Concerning biological evaluation all the studied dietary oils compared to positive control group caused an decreases in serum LDL-c and TC and significantly increased HDL-c over the feeding period of experimental rat groups, thereby decreased the TC/HDL-c and LDL-c/HDL-c ratios. Aspartate transaminase (AST), alanine transaminase (ALT) enzymes and albumin in rats serum were generally decreased by RPO, SRPOL and drug Lipitor compared to positive control group.     Also urea, creatnine and uric acid levels in rats serum were significantly decreased by the studied oils and drug. However, a significant increment in the activities of glutathione peroxidase (GPXs), catalase and total antioxidant were observed in blood of hypercholesterolemic rats treated with RPO, SRPOL and drug. As such, the treated groups showed a significant decrement in malondialdehyde (MDA) in plasma.

The study aimed at maximizing the utilization of rice straw and the economic return of rice straw recycling, leading to an increase in the economic return of the farms, which in turn leads to increaseing the added value of the agricultural sector on the one hand, and preserving the environment on the other hand. Rice straw, due to the increase in plant waste year after year, and the decrease in environmental awareness among the majority of farmers. The study was conducted at the level of Sharkia governorate and through the geographical distribution of rice straw at the level of the Sharkia centers. About 10.3% of the average production of Sharkia Governorate during the study period. The study relied on the first two sources in the preliminary data obtained from the questionnaire form.    The second source was the published secondary data published by the research authorities in the process of recycling agricultural waste. Eightyfive percent of the study sample had an idea of recycling. The largest source of their knowledge is the role of the agricultural association and the agricultural supervisor, and the farmers' proposals for tobacco The number of straws on the eastern level was estimated at 49.7 thousand pounds. If they were recycled, they would achieve a material return of 24 million pounds, and the amount of hay at the level of the republic was estimated at 2.91 million tons. In addition, it was found that the center of Zagazig ranked first in terms of the amount of rice straw burned in the governorate (the most needy centers are aware of the pollution of the environment, which increases the risk that it is considered the highest place Population density in Sharkia governorate.

The study aimed to identify and compare changes in  consumer spending patterns in general and food expenditure in particular in both rural and urban areas during the period (2004 / 20052014 / 2015) Moreover  and the economic and monetary changes affecting the standard of livinghas also made in Egypt.  The study was based on quantitative and descriptive statistical methods such as arithmetic mean, rate of change and percentages, estimating the marginal slope of expenditure, and the elasticity of expenditure of the main food groups, and use of some quantitative analysis methods as a test of the difference between the average of two independent samples, (2004/05, 2014/2015), as well as some studies and research related to the subject of the study.  The results showed that the percentage of expenditure on food and drink in both rural and urban areas decreased from the total annual expenditure per capita in 2014/2015 compared to 2004/2005 and that it ranked first among the various expenditure groups during the two study periods and vice versa to the low rate of expenditure on housing in rural areas, the urban expenditure rate increased during 2014/2015.   The results showed that the relative importance of urban rural food expenditure, which was reflected in the reduction of the rural-urban food gap, increased from 27.6% to 14.5%. And vice versa, the percentage increased of the rural- urban nonfood gap, from 50.6% to 42.8% during the two study periods. However, the statistical is no significance of the difference between the average of two samples for the total expenditure, food and non-food between rural and urban during the two periods.  Results also showed an increase in expenditure on some food groups such as meat, vegetables, cheese, eggs, fish and non-alcoholic beverages, and the decrease in per capita expenditure on cereals and bread in both rural and urban areas during 2014-2015 compared to 2004/2005  The results showed the variation in the elasticity of the expenditure of the food and drink group in both rural and urban areas, some of which were necessary and some of them were morenecessary during 2004/2005. However, they increased per capita in rural areas for all food commodities during 2014-2015, However, most of the food commodities in urban areas is necessary commodities.  With reference to the political and monetary changes that occurred during the last ten years, the results of the study showed that the percentage of families living below the poverty line in the rural areas and their urban rise in 2014/2015 compared with 2004/2005, which means that the urban poor are more affected by their rural, The percent age of households living below the absolute poverty line in both rural and urban areas decreased in the second year compared to the first year. The percentage of non-poor households in both rural and urban areas increased in the second year compared with the first year, which indicates improvement Relative to the living conditions of some rural families, While in urban areas, the decline in the proportion of semi-poor families and the increase in the proportion of both poor and non-poor  households makes the change in living standards either positive or negative, but the study suggested that there was a transmission to those who were on the edge of poverty to below the poverty line, A change in the consumption pattern, which was affected by the high prices of most food commodities, especially meat and poultry and try to find different alternatives, whether from fish or from eggs and milk derivatives.
