For this purpose, the effect of Thidiazuron (TDZ) on callus induction and number of subcultures of Salvia splendens was studied. The results showed that the MS medium supplemented with TDZ (0.5 mg/l) and Indole Acetic Acid IAA (0.1 mg/l) produced the highest percentage for explants producing callus (60%). For shoot multiplication, the best results were achieved when shoot tips were cultured on MS medium supplemented with TDZ (0.2 mg/l) alone. For subculture the same concentration of TDZ (0.2 mg/l) in media of eleven subcultures were performed at 21-day intervals over a total period of 231 days. For molecular variation detection, SCoT molecular markers were employed. Five SCoT primers were used and a total of 24 bands were obtained. The results showed high level of polymorphism between parent and their regenerated plants (subculture No. 11). These markers revealed distinctly different patterns of DNA fragments in all somaclones, and some distinctive bands were linked to the regenerated plants. For rooting, the best rooting percentage (100.00%), highest number of roots/shoot (7.00) and root length (2.58 cm) were observed when the shoots were cultured on MS hormone-free medium supplemented with 15 g sucrose/l. Plantlets were successfully acclimatized on Peat moss + perlite (1:1) with a survival rate of 100 %.","PeriodicalId":470407,"journal":{"name":"Assiut Journal of Agricultural Sciences","volume":"49 20","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141814794","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 present study aimed to produce functional Karish cheese fortified with different types and ratios of microalgae powder ( Chlorella vulgaris and Spirulina platensis ) and evaluate the role of fortification with those algae on the quality of the product. Karish cheese was incorporated with C. vulgaris and S. platensis powder, separately at three levels 0.5, 1.0 and 1.5%. The evaluation of chemical composition, salt content, color parameters, antioxidant activity, total phenolic and total carotenoids content, texture profile and organoleptic properties of Karish cheese fortified with microalgae were determined. Addition of microalgae to Karish cheese showed an increasing (P<0.05) in total solid content, protein, ash, acidity and enhanced the texture profile in the final product compared with control sample. Also, the results indicated highest content of antioxidant activity, total flavonoid and total phenolic among all treatments compared with control. Organoleptic preferred Karish cheese samples enriched with microalgae especially with 0.5 and 1.0 % level consequently. Based on these results microalgae powder enriched cheese may have a great benefit for the industry to improve the texture, shapes and the functional nutraceutical properties of the products.","PeriodicalId":470407,"journal":{"name":"Assiut Journal of Agricultural Sciences","volume":"109 33","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141820302","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}

Selection criteria included seed yield/ plant (SY/P), number of pods/ plant (NP/P), and seed index (SI). Analysis of variance revealed significant differences among families within the F 3 and F 4 generations for all studied traits, indicating successful selection progress. Notably, mean values for all traits, except days to flowering, increased from cycle 1 to cycle 2. Days to flowering exhibited the opposite trend, with a higher mean value observed in cycle 1. The expected gain from selection ( EGS%) for SY/P in the F 2 generation was 29.52 and increased in the F 3 and F 4 generations in values of 34.41 and 2.06, respectively. The realized gain from selection ( RGS%) for SY/P in the F 3 generation was 23.06, then decreased in successive generation which amounted to 9.56 in F 4 . Multiple promising faba bean genotypes were identified within Families 1, 2, 13, 56, and 60. These families exhibited superior performance in relative yield traits compared to the better parent, check variety, and bulk samples. Additionally, they displayed favorable values for most characters assessed. These findings suggest their significant potential for incorporation into breeding programs to enhance faba bean yield.","PeriodicalId":470407,"journal":{"name":"Assiut Journal of Agricultural Sciences","volume":" 30","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141824884","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}

Twenty-four healthy male Farafra lambs (5 and 6 months old and 30 ± 0.50 kg body weight) were randomly divided into four groups. The first group was fed on 60% of the concentrated feed mixture (CFM) and 40% wheat straw as DM and served as a control. The other 3 treatment groups (10 MOL, 20 MOL, and 30 MOL), partially substituted the crud protein of the CFM at rates 10, 20, and 30% with Moringa oleifera leaves protein, respectively. The results revealed that dietary MOL had no significant effect on body weight gain, however they may adversely be affected by increasing the levels of MOL. The inclusion MOL at 20% in the diet of lambs increased (P <0.05) WBC’s count particularly neutrophils as compared with other groups. Also, MOL groups tended to be higher in RBC’s count and percentages of HG and HCT than control one. The plasma albumin was decreased (P˂0.05) with increas ing levels of MOL in the diets of lambs. Also, the urea concentration and ALT values were lower (P˂0.05) with MOL supplementation at Levels of 20 and 30% than that in 10% group. It could be concluded that the partial substitution of concentrate feed with Moringa oleifera leaves up to 10 % growing lambs' diets can improve growth performance, blood hematology, and plasma constituents, and exert protective effects in the liver without inducing adverse effects on animal health.","PeriodicalId":470407,"journal":{"name":"Assiut Journal of Agricultural Sciences","volume":" 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141828107","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}

Twelve bread wheat cultivars (Giza 168, Giza 171, Sids 1, Sids 12, Sids 14, Gemmeiza 9, Gemmeiza 11, Misr 1, Misr 2, Misr 3, Shandwell 1 and Sakh 94) were grown at three planting dates (November 20, December10 and December 30). Each planting date in each season was considered as a separate experiment. The experimental design for each sowing date was a randomized complete block design (RCBD) with three replications. The obtained result show that the tested sowing dates, bread wheat cultivars and their interaction had a highly significant effect on height of height and spike length, spikes number m -2 , number of kernels spike -1 , 1000-kernel weight and grain yield fed. -1 in both seasons. Moreover, sowing Sids 12 bread wheat cultivar on 20 November recorded the high average values of grain yield (3.03 and 3.11 ton/fed. in the two respective seasons). As for the heat sensitivity index (H.S.I), 6 out of 12 cultivars showed H.S.I values less than unity for the second planting date and 5 cultivars for the late planting date in both seasons, which indicates that these varieties were more tolerant to heat stress.

Additionally, the study explored the influence of invertase activity on reducing sugars content in sugar beet roots. Results indicated that covered storage conditions exhibited the lowest invertase activity compared to open air and room storage conditions. Moreover, reducing sugars content was affected by invertase enzyme activity. Storage conditions displayed the lowest inverted sugars content across all tested sugar beet root varieties.
