The earliest date (15th October) recorded the best results regarding all fennel growth, yield and fruit constituents of volatile oil yield. Foliar application of humic acid in high concentration (4.5 g/ml) showed significant impact on plant height, branch number/plant, stem diameter, number of umbels/plant, fruit yield/plant, total fruit yield/feddan, volatile oil percentage, volatile oil/plant and volatile oil/feddan during both seasons. Volatile oil of fruits collected from plants sown in mid-October induced the highest percentage of anethole (74.96 %) and the lowest percentage of estragole (15.37%) in comparison with the plants sown in the beginning and middle November. The higher concentration of humic acid increased the percentage of anethole comparing with other concentrations. The foliar application by humic acid in high concentration of fennel sown in mid-October seems to be the best combination for getting higher fruit yield and high quality of volatile oil.","PeriodicalId":40934,"journal":{"name":"EGYPTIAN JOURNAL OF VETERINARY SCIENCE","volume":"47 1","pages":"81-92"},"PeriodicalIF":0.5,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44666652","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}

Experiment contained two branch lengths (275 and 150 cm) and six treatments of IBA (100, or 200 ppm) and B. subtilis suspension (5 or 10 ml/air-layer from suspension 108 CFU/ml) added individually or in combinations. The best results were obtained by 200 ppm IBA and/or 10 ml B. subtilis resulting in the maximum rooting percentage (100%), the highest number of roots (58.66/layer), the longest root (26.50 cm), large root volume (86.46 cm3/ layer), the heaviest fresh and dry roots (82.68 and 13.50 g/layer, respectively) and maximum percentage of layers showing secondary roots (100%). These results were correlated with highest total carbohydrates content (28.40%) and total phenolic compounds (52.41 mg Gallic acid equivalent/g DW).

The obtained data revealed that irrigation of cuttings with NaCl at 2000 and 4000 ppm resulted in a significant reduction in rooting percentage, root and vegetative growth characteristics, contents of N, P and K as well as C/N ratio in cutting tissues compared to control and the lowest salinity level used, whereas Na % and Na/K ratio were high, especially at high salinity levels. Treatment of cuttings with IBA alone or combined with B. subtilis modified and alleviated most of the harmful effects of salt stress, especially at the lower salinity level. Generally, the combination of IBA at 50 ppm with B. subtilis had a profound effect in increasing rootability, root and vegetative growth characteristics of plants compared to the control and all other treatments. The same treatment increased contents of N, P and K as well as C/N ratio, whereas reduced Na % and Na/K ratio in the rooted cutting tissues. So, it could be recommended to use this treatment for alleviation of adverse effects of irrigation water salinity on rooting and growth of R. officinalis cuttings.","PeriodicalId":40934,"journal":{"name":"EGYPTIAN JOURNAL OF VETERINARY SCIENCE","volume":"1 1","pages":"0-0"},"PeriodicalIF":0.5,"publicationDate":"2019-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41808839","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}

Intensive agricultural pollution arises from both natural (geological) and anthropogenic activities i.e., various stationary and mobile sources (Bilos et al., 2001). Agricultural amendments e.g., sewagesludge, mineral synthetic fertilizers and pesticidesrelease large quantities of HMs (Anagawa et al., 2019), exceeding critical limits i.e., 60mg/kg Pb and 70mg/kg Cu in the soil according to FAO/WHO (2001).This is acutely evident inEgypt, especially in areas adjacent to the highways, domestic wastewater and industrial zonewhich pose a critical concern to plants,environment and human at the end of the food chain. In northeastern of the Delta, particularly in Talkha, an industrial and agricultural city, the soil is heavy in texture with relatively high pH, low organic matter and contaminated by copper and lead, besides low quality irrigation water which was a mixture of industrial waste from El Delta Fertilizers Co. and sewage and agricultural wastewaters. THE PRESENT study was carried out during the summer seasons of 2017 and 2018 in Talkha city, Dakahlia Governorate, Egypt near El-Mansoura-Damietta highway and El Delta Company for Fertilizers and Chemical Industries, where lead (Pb) and copper (Cu) levels in the soil exceed the permissible levels. Therefore, the aim of this study was to alleviate the adverse effects of heavy metals (HMs) on tomato plant (Solanumlycopersicum L.) Super Strain B F1. Twelve treatments were conducted which were the interactions between two silicon (Si) foliar spraying (without or 300 ppm Si) and six soil amendments : 100% chemical fertilizers (CF), 50% farmyard manure (FYM), 100% FYM, 100% CF+ Trichoderma spp. (T.), 50% FYM + T. and 100% FYM + T. Data indicate that Pb and Cu were accumulated in tomato organs to hazardous levels in the following descending order : roots > shoots > fruits and shoots > roots > fruits, respectively which consequently severely reduced tomato plant growth and fruit yield and fruit quality. Results also, showed that the application of Si treatment sole or in combination with soil amendments markedly enhanced plant height, dry weight, total chlorophyll, number of fruits/plant, total yield/fed, Vitamin C, acidity %, TSS and taste index, where as, reduced Pb and Cu concentrations in different plant organs, bio-concentration factor (BCF) and translocation factor (TF). However, Si + FYM + T. treatment was superior in these respects, therefore increased the net return. Also, negative correlations were obtained between fruit yield and BCF of Pb or Cu and between taste index and TF of Pb or Cu.","PeriodicalId":40934,"journal":{"name":"EGYPTIAN JOURNAL OF VETERINARY SCIENCE","volume":" ","pages":"0-0"},"PeriodicalIF":0.5,"publicationDate":"2019-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49305144","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 study was carried out at El-Dalgamon village, Kafr El-Zayyat, El-Gharbiya Governorate, Egypt, during the two successive summer seasons of 2016 and 2017.The accessions were arranged in a complete block design with three replications. The Tocher optimization method and unweighted pair group method with arithmetic mean (UPGMA), were used for clustering based on Mahalanobis D2 statistic as a dissimilarity measure. The results indicated a wide genetic variability for all traits. The accessions were grouped into five clusters by Tocher’s method.Cluster I was the largest, comprised 22 accessions, cluster II, which included the accessions NGB17827 and NGB17823, had the maximum inter-cluster distances with the other clusters, while each of the remaining three clusters contained only one accession. There was an agreement between UPGMA hierarchical clustering and Tocher optimization method.To obtain superior recombinants in segregating generations, we suggest investigating the crossing combinations of Giza 6 with, NGB17817, either of NGB17823 or NGB17827, and the desired accessions from cluster I, such as NGB17806, NGB17814, NGB17816, and NGB18054.
