Walp. sub. sp. sesquipedalis) is a climber annual Vigna crop of Leguminosae family with chromosome number 2n = 2x = 22. It’s known as long-podded cowpea, asparagus bean, pea bean, snake bean, garter bean and Chinese long bean. It has ability to fix atmospheric nitrogen with its symbiotic bacteria (Rhizobia) and increases productivity of the soil (Pandey et al., 1989). It is much more a climbing and trailing plant than the cowpea, often reaching 9-12 feet in height and it is characterized by its very long pods 30-90 cm in length with seeds usually 8–12 mm long. It is commonly cultivated T study was carried out to identify the genetic variations in yardlong bean plants irradiated by various doses (75, 150, 300, 450 and 600Gy) of gamma rays using RAPD and ISSR markers techniques as well as, their effect on some vegetative traits were studied. ten RAPD and 10 ISSR markers were used in this investigation. The obtained results showed that the ten RAPD primers produced 117 bands only 94 of them were polymorphic while 23 bands were monomorphic. The percentages of polymorphism among primers ranged from 0.0% to 100%. All of the RAPD primers produced unique bands except OPK-06 primer which did not produced any unique bands. Meanwhile, 62 amplified bands including 26 polymorphic and 36 monomorphic bands were generated by ten ISSR primers. All of the ISSR primers did not produce any unique bands except ISSR4 primer which produced only one unique band, these results demonstrated that this unique sequence could be used as a molecular marker associated with gamma irradiation. The field results showed that the emergence percentage decreased with increasing doses up to 600Gy treatment which gave the lowest emergence percentage. Inconstant values of vegetative characteristics were obtained after each treatment with gamma ray doses; 300Gy treatment gave the highest value of plant height, number of branches, pod length and number of seeds per pod compared to control and other treatments. The values of coefficients of phenotypic and genotypic variation, heritability and expect genetic advance did not follow regular increase or decrease with the radiation doses in both seasons. The present data demonstrate that using gamma rays to induce DNA polymorphism in this plant genome which might be lead to appearance of a desired phenotype and genetic characteristics which could be used in yardlong bean improvement programs.","PeriodicalId":40934,"journal":{"name":"EGYPTIAN JOURNAL OF VETERINARY SCIENCE","volume":"48 1","pages":"123-139"},"PeriodicalIF":0.5,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49136532","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}

At this moment, there is about 3.6 million fed. of citrus spp. cultivated at commercial scale in the world yielding nearly 40 million metric tons of oranges, lemons, limes,... etc. In Egypt, citrus has great attention due to its importance for local consumption and consider a popular fruit for it’s low acidity, juicy pulp and good flavor. All over, citrus fruits have an important role to prevent human cardiovascular diseases, and source for foreign currencies by exportation to the world markets. Recently, citrus cultivated area has increased rapidly with the reclamation of new desert lands reaching about486650 fed. And Valencia orange occupied 139851 fed. (28.74 % of total area) (Ministry of Agriculture and Land Reclamation, 2018). Fruit harvested through March to June period. In Egypt many Citriculture regions suffer from a low organic matter and high alkaline with limited phosphorus availability which causes, many problems are encountered that threatening some citrus growers and been among the difficulties hindering more extension. Generally, alkaline soil is a serious problem especially in arid or semi-arid regions. Irrigated water pH value is an important feature of water. Predecessors have reported the effects of different pH treatments on plant growth in Metroxylon sagu (Anugoolprasert et al., 2012), Camellia sinensis (Ruan et al., 2007), Chlamydomonas acidophila (Gerloff-Elias et al., 2005), Anabaenopsis elenkini (Santos et al., 2011) VALENCIA orange (Citrus sinensis) seedlings on Sour orange (Citrus aurantum ) “ SO” or Volkamer lemon (Citrus Volkamariana) “ VL” fertilized with three nutrient doses 50 ; 75 and 100 percentage of nursery recommendation and irrigated with water at four pH levels : the control ; pH5 ; pH7 and pH9. .Results showed that; Valencia orange seedlings on both SO or VL stocks gave the best stem: height and diameter; leaf area; root length and width; under 50% or 75 % nutrient doses of nursery recommendation when irrigated with water at pH7.

It has been demonstrated that garlic was grown and consumed by ancient Egyptian, about 2780 2100 B.C., (Yamaguchi, 1983). Egypt is one the world’s top garlic producing countries, it is ranked as the fourth country among garlic producers, with an annual production of 286,213 tones produced from 127,82 ha (FAO, 2018). In Egypt, garlic is grown mainly for local consumption, however Egypt is one of the top ten garlic exporter countries with 0.9% of total worldwide garlic exportations with a net return of 27 million dollars. Garlic cloves have several bioactive compounds, such as allicin, alliin, diallyl sulfide, diallyl disulfide, diallyl trisulfide, ajoene, and S-allyl-cysteine, which contribute to the garlic’s taste (Kilgori et al., 2007, Shang et al., 2019). Owing to its diverse and valuable compounds, several earlier studies have been reported that garlic and its bioactive ingredients can positively contribute to human health as anti-oxidant, anti-inflammatory, anti-microbial, anti-cancer, anti-diabetic and anti-obesity (Shang et al., 2019). In addition, garlic’s oil has several agriculture actions, such as herbicide, acaricide and insecticide (Abouziena et al., 2009, Ismail et al., 2011, Sharaby et al., 2012). Furthermore, it has a stimulatory effect on onion plants grown under sandy soil conditions T successive field trials were performed at the Agricultural Research Farm of the Faculty of Agriculture, Suez Canal University during the two successive of 2018/2019 and 2019/2020. to investigate the influence of 0, 0.5 and 1 mM of indole 3-butyric acid (IBA) and 0, 1, 1.5 and 2 mM myo-inositol (MI) and their interactive as folair application on vegetative growth, bulb yield, biochemical constituents and mineral contents of garlic plants cv. Seds 40. The treatments were laid out in a split plot order with three replicates. The obtained results reported that garlic plants positively responded to the exogenous treatments of IBA and MI individually or interactively. It showed generally that application of IBA at 0.5 mM recorded the highest values of vegetative growth, yiled, quality parmemters as well as the mineral content (N, P and K). In the same regard, application of MI at 1.5 and 2 mM significantly promoted moast of studied traits compared to control and the rest of MI concentration, in both growing seasons. Furthermore, the two-factor interaction was found to be significant for all measured traits in both seasons, except for K content. Whereas, exogenous treatment of IBA at 0.5 mM along with exogenous treatment of MI at 1.5 and/or 2 mM resulted in the highest means of most of the above mentioned traits. Thus, it could be suggested that applying a combination of IBA and MI was found to be effective for enhancing vegetative growth, bulb yield and quality as well as macro-elements content.","PeriodicalId":40934,"journal":{"name":"EGYPTIAN JOURNAL OF VETERINARY SCIENCE","volume":"48 1","pages":"111-122"},"PeriodicalIF":0.5,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47086849","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}

Likewise was the eggplant, except a marginal total yield difference that was in favor of transplants grown in the spent mushroom compost growing media. The increment in fruit weight for eggplant was noticed in one year only for those plants derived from transplants grown in the spent mushroom compost growing medium.
