This study aims to evaluate the growth of castor bean on different soils as affected by wastewater (sewage effluent) irrigation. Thus, castor bean seeds were sown in six different soils (sandy soil - sandy soil + compost - polluted soil - clay soil - calcareous soil - saline soil) and irrigated using equal amounts of sewage effluent. The physical and chemical properties of the soils used and the chemical constituents of sewage effluent were investigated. The results showed that the highest percentage of germination of castor bean seeds (96.6%) were achieved in the clay as well as sandy soil with added compost, followed by sandy soil (92.2%). On the other hand the lowest germination percentages were shown with the seeds sown in calcareous soil (50.3%) and saline soil (30.3%). The time duration required for the radical protrusion was also shortest (quick germination) and longest in the polluted, calcareous, and saline soils. There has been also a marked impact on the plant growth, fresh weight and dry weight gain of, where highest values were shown with the plants cultivated in clay soils followed by sandy soil with added compost. These plants exhibited in addition best criteria (weight, length, width). Thus, the results obtained confirmed the ability of castor beanto grow in different types of soils under irrigation by sewage effluent.","PeriodicalId":13776,"journal":{"name":"International Journal of Biosciences","volume":"11 1","pages":"15-22"},"PeriodicalIF":0.0,"publicationDate":"2015-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73306525","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}

L) is a dioecious, monocot and tropical fruit that requires pollination for fruit set and economically production. It is propagated by offshoot routinely. The low number of offshoot and short time of offshoot production are considered as the most disadvantages for its propagation. Since 20 th century, propagation of date palm through tissue culture techniques is conducted. Embryogenesis and organogenesis are the two main techniques for in vitro propagation of date palm. Somaclonal variation is the most problem in tissue culture of date palm that impose difficulties for growers. So, finding the easy and inexpensive method to control stability and uniformity are the most important factors in tissue culture propagation of date palm. In this experiment, we evaluated the qualities of tissue culture date palms c.v Berhee by analysis of some morphological characters. There was a lot of variation between propagated trees. It was noticed that some morphological factors can be considered as key factors to screen the type and off-type trees in this cultivar.","PeriodicalId":13776,"journal":{"name":"International Journal of Biosciences","volume":"2 1","pages":"117-122"},"PeriodicalIF":0.0,"publicationDate":"2015-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82139999","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}

Seeds of the species were collected from Mansehra, Batagram and Muzaffarabad Districts in November, 2013. Mature and ripened seeds were collected in suitable season from the selected sampling sites in polythene bags. Some of these collected seeds were scarified while others were subjected to stratification treatment only. Stratified treatments were given to the seeds for 10, 15 and 20 days in the laboratory. Others were scarified with knife and forceps. In stratified seeds, maximum germination rate i.e. 95.45% were observed in seeds collected from Batagram District while the lowest rate was observed in seeds collected from Mansehra District. Like-wise, for scarified treatment, maximum germination rate i.e. 100% was obtained in seeds collected from Batagram and Mansehra districts while in Muzaffarabad District lowest rate of germination i.e. 83% was observed. Scarified treatments proved to be more effective for this species as compared to stratified treatments. Therefore, these methods should be followed for the seed germination practices of these species and regeneration on larger scale.","PeriodicalId":13776,"journal":{"name":"International Journal of Biosciences","volume":"2 1","pages":"42-48"},"PeriodicalIF":0.0,"publicationDate":"2015-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76309320","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}

In this study the effect of three media contains WPM, MS and QL and three different growth regulators combinations (0, 0.5 and 1 mgL -1 BA, 0.1 mgL -1 GA3 and 0.1 mgL -1 IBA) were investigated on regeneration of two Sweet cherry cultivars cvs. \"Bing\" and \"Dovomras\" in spring season. All experiments were arranged in completely randomized designed. Each treatment contained three replicates. Explants were soaked in 100 mgL -1 ascorbic acid and 150 mgL -1 citric acid for one hour before surface sterilization to prevent browning during in vitro culture. The meristem explants (0.5-0.7 mm) cultured in media and maintained at 26°C under a 16 hr-light/8 hr-dark with a light intensity of 2000-3000 lux from white fluorescent light. After six weeks, survival, necrosis and contamination percent were studied. The results showed that WPM medium induced the most survival percent in both cultivars. MS medium decreased the survival percent and maked the highest necrosis percent in both cultivars. Cultivars showed different responses to concentration of BA, so that, \"Bing\" cultivar in 1 mgL -1 BA and \"Dovomras\" in 0.5 mgL -1 BA had the best response (55.53-38.96%).
