Whereas the nutritional value of pulses is generally recognized, the presence of antinutritional elements in their composition limits their use. Effect of soaking and germination process on removal or reducing of (total phenolic, tannins and phytic acid) content of commonly consumed pulses in Egypt were studied. Four pulses namely faba bean (Vicia Faba) Giza 843, chickpea (Cicer arietinum) Giza 1, cowpea (Vigna unguiculata) krymy 7 and soybean (Glycine max) Giza 111 were used in this research. The total phenolic compounds, tannins, and phytic acid content of four pulses were significantly decreased after soaking for 12 hours and germination treatment for varied periods (24, 48, and 72 hours). On a dry weight basis, the phenolic compounds content of raw pulses was 370.9, 132.5, 763.4, and 249.4 mg/100g, for faba bean, chickpea, cowpea, and soybean respectively, while tannin content was 684.5, 488.1, 390.9, and 225.5 mg/100g, and phytic acid content was 1050.6, 719.2, 987.2, and 1076.2 mg/100g. Soaking for 12 hours significantly decreased the concentration of total phenolics, tannins and phytic acid contents of the investigated pulses by 4.0-22.7%, 7.1-26.5% and 7.0-15%, respectively. Germination process for 72 hours reduced total phenolics, tannins and phytic acid contents of studied pulses by 21.4 -56.9%, 23.9-64.8% and 54.6-65.0%, respectively. From the obtained results it could be concluded that the reduction of antinutritional factors content was increased with the progress of both soaking and germination periods in all studied pulses.

This manuscript aimed to study the effect of co-exposure of both lead acetate and titanium dioxide nanoparticles (TiO2 NPs) on the major histocompatibility complex (Mhc) region and 16S rRNA sequence in vivo. Twenty-four male albino Swiss mice have randomly separated into four groups; Group 1 (control): was received only distilled water. Groups 2-4 received lead acetate (400 mg/kg body weight, orally by gavage for 15 consecutive days) + either distilled water (orally), or ZnCl2 (4 mg/kg body weight, intraperitoneal injection), or titanium deoxidize nanoparticles TiO2 (200 mg/kg body weight, intraperitoneal injection) for additional 15 consecutive days, respectively. According to the results of 16S rRNA sequence that the highest P-distance value (0.002) found between control group and both (lead acetate and lead acetate+TiO2)-treated groups which reflected the genetic effects of both lead acetate and TiO2 NPs. The results of microsatellites revealed that the exposure to lead acetate affected the genetic structure, where the genetic similarity between control group and lead acetate-treated group was 0.83, while zinc chloride decrease lead acetate-induced genotoxicity where the genetic similarity was 0.88 comparing to the control group. Moreover, the co-exposure to lead acetate and TiO2 NPs led to more genotoxicity and DNA damage, that is clear in the genetic similarity between control group and lead acetate+TiO2-treated group which was 0.74.

Heat stress is one of abiotic stress that has deleterious effects on crops yield. Therefore, this study aims are to evaluate heat-tolerant maize lines and characterizing them by DNA molecular markers. Inbred lines were generated for two generations by selfing pollination. They were evaluated in each generation for the performance of some agro-morphological traits under normal and heat stress conditions. All the traits of the S1 and S2 inbred lines varied significantly among them under both conditions, except plant height was not significant under heat stress for the S1 lines. The L6 inbred line had the highest yield under the stress conditions in both S1 andS2 generations. Moreover, the heat susceptible index showed that the lines, L6 and L40 were the highest tolerant in the both generations. Furthermore, cluster analysis based on morphological traits for the 5 selected S2 inbred lines could be able to isolate the worst S2 inbred line under heat stress conditions in an independent cluster. In addition, they were characterized by ISSR and SRAP molecular markers. The ISSR detected higher polymorphism (79.79%) than SRAP marker (58.46%). The ISSR clustering patterns managed to classify the highest yield line (L6) under the heat stress in a separated cluster, but both the SRAP and combined isolated the worst line (L32) in one cluster. The Mantel’s test showed a positive correlation among all the studied markers. Additionally, the correlation was significant and highly strong (r=0.915) between morphological traits under normal conditions and SRAP marker. However, the identified S2 inbred lines with resistance to heat tolerance could be a beneficial source in the development of heat-tolerant maize hybrids.

The present investigation was carried out to determine the effect of growing season on four sunflower genotypes (Sakha 53, Giza 102, L120 and L770) at Shandaweel agricultural research station, Agricultural Research Center, Egypt during the two years 2019 and 2020 for yield, its components and oil quality sown during winter and summer seasons. A randomized complete block design with 3 replications. The combined analysis showed that growing season had significant effect on genotypes for yield components and chemical properties. The highest each of content of oil (44.20%), total protein (21.33%) in seeds and the best oil quality recognized the highest proportion from unsaturated fatty acids (TMUF % and (TPUF%) with high oleic acid and linolenic acid, low proportion saturated fatty acids were in winter season. The summer season produced the highest 100-seed weight, yield/plant and seed yield/fed. The genotype L120 had the heaviest 100-seed weight (6.88 g) and yield/plant (48.15 g) and seed yield/fed (1223.90 kg) in summer season. Giza 102 recorded the highest proportion in TMUF % (18.16) and oleic acid% (17.10), L770 recorded the highest proportion in TPUF % (75.50) and Linoleic acid % (73.40). Correlation coefficients among various studied characters and seed yield/fed in sunflower genotypes across the environments demonstrated that seed yield (kg/fed) were positively associated and highly significantly with head diameter, 100-seed weight and seed yield/ plant and between oil percentage with 50% flowering and steam diameter across the seasons and years.

Drought is one of the significant abiotic stress factors that affect plant development and productivity. Screening and producing of more tolerant genotypes with higher yield capacity is the breeders' principal purpose. Therefore, this work was carried out to evaluate the performance of four sugar beet cultivars (Top, Hossam, Hercules and Kawamera) under water limitation. The drought stress experiment was applied based on three water regimes, 25%, 50% and 75% (severe, moderate and non-stress conditions, respectively) of relative water capacity (RWC). The study incorporated some productivity and quality traits. The results showed that drought stress has a significant effect on all studied traits. Whereas, increasing of water deficiency led to decrease of the productivity traits and increasing of quality parameters. Kawamera cultivar has superior performance in all the studied traits under all three different levels of water regime. Besides, the four cultivars were assessed by both SSR and ISSR molecular markers. SSR marker exhibited a higher polymorphism percentage (71.43%) than ISSR marker (44.26%). In addition, the mean polymorphism information content (PIC) value was higher for the SSR marker (0.25) than the ISSR marker (0.18) too. Moreover, the constructed dendrograms revealed that the SSR marker was able to separate the cultivars according to their drought-tolerance, where the highest drought-tolerant cultivar (Kawamera) was classified alone in the main cluster. However, the superiority of Kawamera cultivar under drought stress indicated that it could be utilized in breeding programs for developing more drought-tolerant sugar beet cultivars.

The main goal of this study was to determine the seasonal abundance of the white butterfly Pieris rapae L. (Lepidoptera: Pieridae) on several local and imported cabbage cultivars in old and reclaimed lands. The impact of certain cabbage metabolites on P. rapae populations was examined, as well as the relative susceptibility of different cabbage cultivars. Damage caused by P. rapae Varies. During the first two months following transplantation, P. rapae can cause economic damage to cabbage plants in both areas. One month later, its population had multiplied several times in the old land. Three of the six tested cabbage cultivars were appeared as susceptible (S) cultivars and harbored high numbers of the pest with an average of 0.63, 0.60 and 0.53 Kenz, Crossina and Ganzory cultivars, respectively. However, the imported white cabbage hybrids, 728, 730 and 747 showed sort of resistance and appeared as low resistant (LR) hybrids and harbored 0.40, 0.41 and 0.45 individuals/plant, respectively. Chlorophyll only showed highly significant negative correlation with P. rapae populations. However, the remaining metabolites showed non-significant positive correlation. In a comparison between P. rapae populations in Assiut (the old area) and El-Fath province (the reclaimed area), it can be note that the pest populations, the damaged (infested and unmarketable) plants were multiplied several times in the later. It can be noted that the general mean of the pest numbers recorded in the reclaimed area (2.14 individuals/plant) was found to equal 4.28 folds more than that recorded in the old area (0.50 individuals/plant).

This study aimed to investigate ameliorative effects of the crude extract (SIE) and polysaccharide (SIP) of the ink of Sepia officinalis, on some biochemical and hematological disorders induced by cyclophosphamide (CP). Forty adult male albino Wistar rats were divided into five groups (n= 8 each). In the control group, rats were administered orally with 0.9% isotonic saline solution at a dose (5 ml/kg b.w.). All the other groups were i.p. injected with a single dose of CP (200mg/kg b.w.) only for one time. Then the third group was treated with oral administration of (SIE) (200mg/kg b.w.) daily for 60 days, the fourth group was treated with oral administration of (SIP) (80mg/kg b.w.) daily for 60 days and the fifth group was treated with oral administration of (SIE, 200mg/kg b.w. + SIP, 80mg/kg b.w.) daily for 60 days. All the animals were slaughtered by the end of the experiment for collecting the blood samples for hematological and biochemical assays. The biochemical results indicated that administration of CP was associated with a significant increase in the levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), urea, creatinine and uric acid. Moreover, a significant decrease in the levels of albumin and total protein was recorded. In addition, hematological disorders including a significant suppression on the numbers of RBCs, WBCs and PLTs, with a remarkable reduction in hemoglobin contents (Hb) and a significant drop in PCV values. Concomitant administration of SIE and SIP alleviated the altered biochemical and hematological parameters.

This examination was conducted during the 2018 and 2019 seasons to examine the effect of foliar application of (0.5 to 2 %) Spirulina Platensis Algae and (50 to 150 ppm) salicylic acid on Flowering (%), growth, yield, and fruit quality of Koroneiki olive trees grown under the sandy soil. The trees received two sprays at the mid of December and the 1st week of Jan. Applications of Spirulina Platensis Algae at 0.5 to 2 % and salicylic acid at 50 to 150 ppm alone, or combination had a pronounced stimulation on vegetative growth, shoot length, leaf area and the number of leaves, percentage of N, P and K in leaves, Flowering (%), yield, fruit weight and dimensions and fruit oils % over the control. The stimulation of these parameters was materially associated with increasing concentrations of both materials. Using Spirulina Platensis Algae was superior to using salicylic acid in this regard. Combination applications were practical than using each material alone in this respect. Application of two sprays at mid-December and the 1st week of Jan. of a mixture of 1 % Spirulina Platensis Algae and 100 ppm salicylic acid gave the best yield and fruit quality results Koroneiki olive trees grown under the sandy soil.

A field experimentt was conducted at a private farm in Sohag, Egypt in 2016-17 and 2017-18 to evaluate planting method, seeding rate and chemical weed control on bread wheat productivity and associated weeds. Weeding treatments were: Pyroxsulam (Pallas) herbicide and the check. Planting methods were: ridges (narrow beds); rows; dry-; and wet- broadcasting. The seeding rates were: 45, 60, and 75 kg/feddan (fed=4200 m2). Results revealed that Pallas significantly reduced the biomass of weeds by 91 % vs. the check. Wet seeding resulted in the smallest biomass of weeds vs. the dry methods. Increasing seeding rate from 45 to 75 kg/fed significantly reduced the biomass of total weeds by 65.8 %. The 75 kg/fed rate + Pallas significantly reduced biomass of weeds. Pallas significantly increased numbers of spikes/m2, grains/spike and grain yield vs. the check. Pallas increased grain yield by 5.4 ardeb (150 kg)/fed vs. the check. Ridges planting had superior effect on numbers of spikes/m2, number of grains/spike vs. other methods. As for grain yield, ridges was the first and rows the second, while wet and dry methods were significantly equal in the third class. The 75 kg/fed seed rate significantly increased spikes/m2 and grain yield. Pallas with 75 kg/fed rate gave the highest values of spikes/m2 and grain yield. Ridges method with Pallas also produced the highest grain yield. The ridges method seeded by 75 kg/fed and treated by Pallas produced the highest grain yield (10.48 t/ha) and could be recommended for producing bread wheat under similar conditions.

Sequence Related Amplified Polymorphism (SRAP) molecular technique was used for assessing the genetic diversity of eight Egyptian bread wheat (Triticum aestivum L.) genotypes. Five SRAP primers combinations were able to expose the polymorphism between the studied genotypes. The percentage of polymorphism (P %) ranged from 40 to 79.90 %. Furthermore, the Polymorphic Information Content (PIC) values for SRAP primers combination varied from 0.11 to 0.31 with an average of 0.19. The ME5F-EM2R and ME1F-EM2R primer combination cleared higher levels of polymorphism of 66.67 and 76.90%, respectively. The results of Single Marker Analysis (SMA) showed that the SRAP marker ME1-EM21320bp could be considered probably as candidate marker linked to spike length in the tested genotypes. Moreover, ME1-EM2900bp and ME1-EM2575bp could be considered as markers linked to plant height and tillers number /plant traits, respectively. Results of Single Marker Analysis (SMA) showed significant marker-trait associations for spike length (P= 0.04), plant height (P= 0.02) and number of tillers/plant (P= 0.03). Me1F-Em6R850bp marker could be also considered as candidate markers probably linked to plant height, with a specific fragment of 850bp for the tolerant genotype (P1). UPGMA cluster analysis based on SRAP markers separated the studied wheat genotypes into three significantly different clusters. The dendrogram based on morphological traits divided the studied wheat genotypes into two different clusters. The Mantel test revealed that there was a positive but non-significant correlation between the genetic similarities based on phenotypic data and SRAP marker (r = 0.36, P> 0.05).
