{"title":"CHEMICAL ANALYSIS, ANTIOXIDANTS AND SUGARS IN WHITE MULBERRY FRUITS","authors":"Asmaa Ali, H.T. Hefnawi, Faten Ibrahim, Lamiaa El-Maghraby","doi":"10.21608/zjar.2023.323817","DOIUrl":"https://doi.org/10.21608/zjar.2023.323817","url":null,"abstract":": The fruits of white mulberry are widespread fruit in Egypt and are eaten by most people with acceptable taste, so we tried in this research to show the chemical composition of the fruits and the effectiveness of white mulberry as an antioxidant and also know the quality of the polysaccharide that is found in white mulberry and study the properties of sugar many in terms of the quality of the structural units involved in the composition and effective groups of its molecular weight and also its ability as an antioxidant and to achieve this purpose we have collected the fruits of white mulberry from The local market of the city of Zagazig was washed and dried and then grinding and storage in appropriate conditions of temperature (4°C) and the chemical composition of moisture, total ash, crude protein, crude fat, fiber and carbohydrates was estimated by the difference and the results were as follows as a percentage of the dry sample of white mulberry fruits (12.02 - 14.42 - 21 - 4.83 - 15 - 59.75) respectively. Total phenols and total flavonoids were estimated through two types of extracts, aqueous extract and alcoholic extract to determine the effectiveness of white mulberry fruiting as an antioxidant, where the results were (23.5–13.9 mg gallic acid/gram total phenolat extract aqueous and alcoholic extract respectively As for the total flavonoids, the results were (1.43 – 2.54 mg Quercetin /gram aqueous and alcoholic extract, respectively, and finally. The antioxidant activity of white mulberry fruits was estimated by DPPH method and the results obtained were (6.66 – 1.97 mg vitamin C/gram aqueous and alcoholic extract respectively. The sugar was separated from many white mulberry fruits and purified and it became clear from the results to obtain two types of sugar many in the fruits of white mulberry differ in molecular weight and also in the type of structural units involved in the composition where the molecular weight sugar was reached 1.25 x 10 4 - 5.29 x 10 4 Dalton and called them fraction 1 and fraction 2 respectively The quality of monosaccharide was glucose – Mannose - Arabenose - fructose - Mannuronic acid in fractions WMP1 or fraction WMP2 It contains the following structural units (glucose - galactose - arabinose - manuuronic acid acid) Through the results obtained from the HPLC device, the quality of the effective groups in polysaccharide fractions in white mulberry fruits was also identified through the infrared spectrum, which showed peaks appear in 1728 - 1619.2 - 3345.6 cm -1 for samples Which indicates the presence of the CH 2 group and the C=O group hydroxyl group, respectively. Through the results obtained, we can say that the consumption of white mulberry fruits provides the human body with natural antioxidant compounds and also a high content of protein, salts and total carbohydrates.","PeriodicalId":23865,"journal":{"name":"Zagazig Journal of Agricultural Research","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135783207","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"A REVIEW STUDY ON THE EFFECTS OF CLIMATE CHANGE ON AGRICULTURE, LIVESTOCK AND FORESTS IN PAKISTAN","authors":"Ismail Rifai, A. Al Khawaja, I.M. Abdul Hameed","doi":"10.21608/zjar.2023.323796","DOIUrl":"https://doi.org/10.21608/zjar.2023.323796","url":null,"abstract":": Climate change is a global threat to the food and nutritional security of the world. As greenhouse-gas emissions in the atmosphere are increasing, the temperature is also rising due to the greenhouse effect. The average global temperature is increasing continuously and is predicted to rise by 2°C until 2100, which would cause substantial economic losses at the global level. The concentration of CO 2 , which accounts for a major proportion of greenhouse gases, is increasing at an alarming rate, and has led to higher growth and plant productivity due to increased photosynthesis, but increased temperature offsets this effect as it leads to increased crop respirat ion rate and evapotranspiration , higher pest infestation, a shift in weed flora, and reduced crop duration. Climate change also affects the microbial population and their enzymatic activities in soil. This paper reviews the information collected through the literature regarding the issue of climate change, its possible causes, its projection in the near future, its impact on the agriculture sector as an influence on physiological and metabolic activities of plants, and its potential and reported implications for growth and plant productivity, pest infestation, and mitigation strategies and their economic impact. The devastations and damages caused by climate change are apparent across the globe, specifically in the South Asian region where vulnerabilities to climate change among residents are high and climate change adaptation and mitigation awareness are extremely low.","PeriodicalId":23865,"journal":{"name":"Zagazig Journal of Agricultural Research","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135783144","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The hydroponic system used in this experiment was the A-shape NFT (Nutrient Film Technique) system. Two factors were under investigation in this experiment; factor (A): iron concentration in the nutrient solution (3 and 6 ppm). Factor (B): irrigation scheduling (irrigation is running for 24 hours/day , irrigation is running for 15min/ hour and irrigation is running for 15 min/3 hour). Results indicated that, increase iron in the nutrient solution from 3 to 6 ppm increased early and total yield, average fruit weight, TSS % and vitamin C content in fruit. Moreover, results illustrated that the more suitable irrigation scheduling for producing strawberry grown in A-shape NFT system was 15min /h; plants irrigated for 15 min each hour recorded the highest values for early and total yield, average fruit weight, vitamin C content in fruit. Furthermore, the best interaction between the two tested factores was iron concentation 6 ppm in the nutrient solution and using irrigation scheduiling (15 min/h) for strawberry plants grown in hydroponics to achieve high yield and quality of strawberry fruits.","PeriodicalId":23865,"journal":{"name":"Zagazig Journal of Agricultural Research","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135783145","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
