A pot experiment was carried out to study the effect of NPK foliar spraying on salt tolerant of tomato plants. Seedlings were grown in plastic pots 30 cm, filled with loamy sand soil. Seedlings were irrigated every week with saline two type’s salts (NaCl and CaCl) at two levels 2g and 4g L. Seedlings were sprayed with foliar spraying containing NPK. Two months later from transplanting of seedlings leaf samples were taken for determination nutrient contents. The result showed that NPK foliar spraying had a positive effect on soil, growth development, yield and the nutrient concentrations in leaf plant of tomato under the impact of adverse salinity. Although the salts levels of soil have an effect on the absorption of nutrients by tomato plant. But, foliar spraying has a positive effect on the concentration of N, K, Ca, Fe, Mn and Cu in plant leaves.
通过盆栽试验,研究了叶面喷施氮磷钾对番茄植株耐盐性的影响。幼苗生长在30厘米的塑料盆里,盆里填满了肥沃的沙土。每周用2g和4g两种浓度的盐(NaCl和CaCl)灌溉幼苗,幼苗喷施含氮磷钾的叶面喷雾。移栽2个月后取叶片样品,测定养分含量。结果表明,氮磷钾叶面喷施对不利盐度影响下番茄土壤、生长发育、产量和叶片植株养分浓度均有积极影响。土壤含盐量对番茄植株对养分的吸收有影响。叶面喷施对植物叶片中N、K、Ca、Fe、Mn和Cu的浓度有正向影响。

Two field experiments were conducted at the Faculty of Agriculture, (El-shatby), Alexandria University, during the summer seasons of 2017 and 2018, in order to study the effect of compost, Halex2 and Seaweed on okra yield and quality (cv. Turkey). The effects of the treatments on the growth, yield and plant nutrient contents of shoots and fruits were determined. The results showed that using T1,T7, T8, T9, T10 and T11enhanced significantly vegetative growth characters (plant height cm, No. leaves/plant, No. of branches/plant, leaf area index cm, shoot, root fresh and dry weights and nutritional status of plants in leaves and fruits) except T2, T3 gave the highest values in chlorophyll reading of leaves. From data it is obvious that T4 gave the lowest mean values of the given characters. Treatments contained Halex-2 and seaweed increased significantly all morphological characteristics and qualities of okra. The treatments (T7, T9, T10 andT12) lead to increase mineral contents, vitamin C and T.S.S. of fruits compared with T4 treatment. The highest values of total yield were achieved by T9 compared with T4. The use of T1, T8 and T9 were also increased mean values of the No. of fruits/plant, fruit length, fruit diameter and average fruit weight significantly compared with other treatments. This study demonstrated the possibility of producing a good yield of okra safe and healthy without any applying chemical fertilizers via integration of compost, Halex-2 and Seaweed algae as a Clean Agriculture technique.
2017年和2018年夏季,在亚历山大大学(El-shatby)农学院进行了两项田间试验,以研究堆肥、Halex2和海藻对秋葵产量和品质的影响。土耳其)。测定了不同处理对青豆生长、产量和芽果养分含量的影响。结果表明:T1、T7、T8、T9、T10和t11处理显著提高了油菜的营养生长性状(株高cm、株高cm、株高cm、株高cm)。叶/工厂,没有。除T2、T3叶片叶绿素读数最高外,T2、T3叶片叶绿素读数最高。从数据中可以明显看出,T4给出了给定字符的最低平均值。Halex-2和海藻处理显著提高了秋葵的所有形态特征和品质。与T4处理相比,T7、T9、T10和t12处理显著提高了果实的矿物质含量、维生素C和tss。与T4相比,T9的总产量最高。使用T1、T8和T9也均增加了第1号的平均值。单株果长、果径、平均果重均显著高于其他处理。本研究证明了将堆肥、Halex-2和海藻作为一种清洁农业技术,在不施用化肥的情况下安全健康地生产秋葵的可能性。

Three important Egyptian olive cultivars (Coratina, Kroneiki and Picual) were collected from different areas: (Horticulture Res. Inst. Giza, Qassaseen Ismaelia and Khatatba) in Egypt on the middle of November, 2016. Triacylglycerol (TAG) compositions were studied. As purity parameters, triacylglycerol composition in the oil samples was determined according to International Olive Council. All types of oils were characterized by three main TAG: OOO + PLP + PoPP, SOL + POO and OOL + LnPP and six secondary TAG: SLL+PLO, SOO, POP, OLL, OOLn + PoOL, and POS + SLS. Furthermore, small amounts (<1.0%) of seven TAG: PLL + PoPoO, PoOP + SpoL + SOLn + SpoPo, OLLn + PoLL, LLL, PoOO, PLLn and POLn + PpoPO + PpoL were also identified in all analyzed samples. OOO was the major TAG found in all varieties from all areas, presented a range from 30.32 to 32.90%. Followed by POO triacylglyceride, which presented a range from 26.45 to 28.36%. Then OOL came in the following representing a range from 12.00 to 13.91%. Results revealed that, there were significant differences among varieties in our study in terms of TAG contents. Moreover, these results are in accordance with those found in the fatty acid composition. At the same time significant differences were clearly found in POO, LLL TAG beside ECN42 values obtained by HPLC analysis.

The purpose of this study was to evaluate the quality indices and sensory evaluation of olive oil samples extracted from three varieties olive (Olea europaea L.), Frangivento (FOOS), Maraqi (MOOS) and Coratina (COOS) growing in Siwa Oasis, and two varieties olive Maraqi (MOOD) and Coratina (COOD) growing in Desert Rood to identify and classify the oil. The samples which were studied collected from Siwa Oasis and Desert Rood region were examined for physical and chemical properties (acidity, peroxide value, ultraviolet spectrophotometric analysis K232 and K270, fatty acids composition and total phenol content. Olive oil was analyzed for fatty acids commonly present in olive oils which are Palmitic, Palmitoleic, Stearic, Oleic, Linoleic, Linolenic, and Arachidic. Oleic acid was found in high percentage ranged from (71.63% in FOOS cultivar up to 76.00% in MOOD), followed by Palmitic, Linoleic, Stearic, Palmitoleic, and Linolenic. Arachidic acid was detected in all olive oil samples but in low percentage. Oxidative stability by Rancimat method and phenolic compositions by HPLC, were analyzed for each oil samples. Small differences were detected depending on the growing area. In general the main phenolic compound (Oleuropein, Hydroxytyrosol, p-Coumaric and Tyrosol), were present in higher levels in the oil obtained from olive oils under this studied. Big difference was observed for total polyphenols content within the cultivars, total polyphenols of MOOD cultivar olive oil was the highest (211.05 mg/ kg oil) while the lowest (139.31 mg/kg oil) was in the COOS cultivar. Resistance to oxidation was assessed by Rancimat method and showed a good correlation with the amount of total phenols. Also, results of the quality indices (free acidity, peroxide value, k 232 , k 270 and sensory analysis) revealed that, all the analyzed oils were classified into extra virgin category according to IOC 2011 (Trade standard for olive oil). Also, results showed that small differences of quality indices between olive oil samples extracted from five varieties under investigation. showed higher perception of bitterness and fruity than the oils growing in Siwa Oasis. These obtained results demonstrated that there was a good correlation between total polyphenol content and sensory properties of the olive oil. This is confirmed by observations of (Kiritsakis et al., 1998).
本研究旨在对生长在Siwa绿洲的Olea europaea L.、Frangivento (FOOS)、Maraqi (MOOS)和Coratina (COOS) 3个橄榄品种以及生长在Desert Rood的Maraqi (MOOD)和Coratina (good) 2个品种的橄榄油进行品质指标和感官评价,以鉴别和分类。对采自锡瓦绿洲和沙漠路地区的样品进行了理化性质测定(酸度、过氧化值、紫外分光光度分析K232和K270、脂肪酸组成和总酚含量)。分析了橄榄油中常见的脂肪酸,包括棕榈酸、棕榈油酸、硬脂酸、油酸、亚油酸、亚麻酸和花生酸。油酸含量最高(fos品种为71.63%,MOOD品种为76.00%),其次为棕榈酸、亚油酸、硬脂酸、棕榈油酸和亚麻酸。在所有橄榄油样品中均检测到花生酸,但含量较低。用紫外分光光度法测定各样品的氧化稳定性,用高效液相色谱法测定各样品的酚类成分。根据种植区域的不同,发现了微小的差异。总的来说,主要的酚类化合物(橄榄苦苷、羟基酪醇、对香豆素和酪醇)在本研究中从橄榄油中提取的油中含量较高。品种间总多酚含量差异较大,MOOD品种总多酚含量最高(211.05 mg/kg油),COOS品种总多酚含量最低(139.31 mg/kg油)。用rangimat法测定了其抗氧化能力,结果表明,抗氧化能力与总酚含量呈正相关。质量指标(游离酸度、过氧化值、k232、k270和感官分析)结果表明,根据IOC 2011(橄榄油贸易标准),所有分析的油都被归类为特级初榨油。结果表明,5个品种的橄榄油样品的质量指标差异不大。表现出比生长在锡瓦绿洲的油更高的苦味和果味。这些结果表明,总多酚含量与橄榄油的感官性能之间存在良好的相关性。(Kiritsakis et al., 1998)的观察证实了这一点。

Fish products are a high-protein consumed food by a large percentage of the population due to its availability and palatability, and the fish industry has developed processed or minced fish products such as fish burgers, fingers and sausages. The aim of this study is to study the dual effect of turmeric utilization as an antimicrobial and an antioxidant. In addition its roles in improving the quality of fish sausage properties during frozen storage at -18 ° C, which improving the shelf life and producing a healthy product. The obtained results indicated that in most estimates fish sausage samples contained 0.0, 0.05, 0.1 and 0.2% turmeric powder showed no significant differences with respect to TBA values in zero time, while significant differences(p < 0.05) were detected among the stored samples at -18 °C for 30, 60 and 90 days .There was, also found a significant increase in the number of milligrams malonaldehyde/kg of sausage during 90 days of storage at -18 °C in all samples, but the turmeric fish sausage samples contained fewer milligrams of malonaldehyde than the control sample: (0.0% turmeric). The microbiological analysis (total number of bacteria, coliform bacteria, Staphylococcus aureus, yeasts and fungi) indicated a significant decrease in log10 cfu/g values with in storage period of 90 days at -18°C. The control sample (0% turmeric powder) had the highest total bacterial count value of fish sausage samples after 30 days storage at -18 °C, while the total bacterial count values were gradually decreased as the turmeric powder concentration was increased during storage at -18°C for 90 days. After 60 days of storage, the untreated samples (control: 0.0% turmeric powder) had the highest value (log10 cfu/g) for Staphylococcus aureus compared to samples contained different concentrations of turmeric powder.The sensory properties of fish sausage indicated that all samples treated with turmeric powder had higher significant differences in taste and overall acceptability compared to untreated samples.
由于鱼产品的可得性和适口性,很大一部分人口食用的是高蛋白食品,鱼类产业已经开发出加工或切碎的鱼产品,如鱼汉堡、鱼手指和香肠。本研究的目的是研究姜黄作为抗菌和抗氧化剂的双重作用。此外,在-18°C冷冻条件下,它还能提高鱼肠的品质和性能,从而延长保质期,生产出健康的产品。结果表明,在大多数估计中,含有0.0、0.05、0.1和0.2%姜黄粉的鱼肠在零时间内的TBA值没有显著差异,而在-18°C保存30、60和90天的鱼肠中,TBA值存在显著差异(p < 0.05),并且在-18°C保存90天期间,所有样品的丙二醛毫克/千克数量均显著增加。但姜黄鱼肠样品中丙二醛的含量比对照样品(0.0%姜黄)少。微生物学分析(细菌总数、大肠菌群、金黄色葡萄球菌、酵母菌和真菌)表明,在-18°C条件下保存90天,其log10 cfu/g值显著下降。对照样品(0%姜黄粉)在-18℃条件下贮藏30 d后,鱼肠样品细菌总数最高,在-18℃条件下贮藏90 d时,随着姜黄粉浓度的增加,细菌总数逐渐降低。保存60 d后,与添加不同浓度姜黄粉的样品相比,未经处理的样品(对照:0.0%姜黄粉)金黄色葡萄球菌的检出值最高(log10 cfu/g)。鱼肠的感官特性表明,与未经处理的样品相比,经姜黄粉处理的样品在口感和总体可接受性方面具有更高的显着差异。
