Ramsey can tolerate salt and drought conditions without decreasing yield production. It has also high resistance to phylloxera and nematodes. From the other side cuttings of Ramsey face rooting difficulties. The aim of this study was to improve cuttings (intermediate and basal) traits of Ramsey via different cultural media (sand; sand: Peat moss, 3:1 v/v; sand: biochar, 3:0.5 v/v (Char1); sand: biochar, 3:1 v/v (Char2) and IBA concentration (0, 1000 and 2000 ppm). Cuttings growth were followed by measuring shoot length and thickness, leaves number per shoot, leaf area, root length, number of root per cutting and root thickness. In addition, cuttings nutritional status of different elements such N, P, K, Ca and Mg were determined. Results showed that two type cuttings treated with 2000 ppm IBA were better than 1000 IBA treatment. Moreover, two type cuttings grown in Char2 media were superior on that grown in Char1 and both were superior on that grown in sand. Hence it could be concluded that using the intermediate cutting with 2000 ppm IBA in biochar media for Salt Creek grape rootstock ‘Ramsey’ propagation.","PeriodicalId":429950,"journal":{"name":"Scientific Journal of Agricultural Sciences","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129581711","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 cactus pear fruits are used in food processing as add value to food products. In this study, cactus pears were grown under three irrigation regimes (T1, T2, and T3) where two of them (T2 and T3) implicated severe deficit irrigat ion conditions on the crop. The relationship between applied irrigation water regimes and fruit physical and chemical properties including antioxidants, pigment and vitamin C content was studied. Also, the aim from this study utilizes cactus pear‟s pulp (CPP), as additive value, in the processing of wheat flour cupcake. Samples of cupcake were made by adding 20%, 40%, 60% and 80% CPP based on wheat flour weight. Fruits obtained under T2 and T3 treatments had higher color concentration than T1. T2 irrigation regime yielded higher contents of total phenolic and flavonoid (TPC and TFC) than those produced under T3 and T1. Antioxidant activity was the highest in T2. Thus, fruits pulp obtained from T2 was selected for cupcake making. The content of soluble solids was 18 Brix in all treatments. Vit C. was significantly higher (P≤0.05) in T3 (56.04 g AA/kg) than T1 (55.42 g AA/kg) and T2 (51.01 AA/kg). The content of betacyanin‟s in T1 was higher (0.47 mg 100mg dry weight) in fruits pulp than T2 and T3 (0.44 and 0.54 mg100mg dry weight).
