The aim was to assess the genetic variation and relationship among the 15 species of subtribe Cassiinaethrough electrophoretic studies of their leaf proteins. Total leaf proteins were extracted and separated on 12% polyacrylamide gels using standard protocols. Young leaves (0.8g) of the plants were washed with distilled water and macerated with sterile mortar and pestle in 0.8% Phosphate Buffer-Saline (PBS) containing 0.4M NaCl at PH 8.0. Results obtained revealed that protein pattern was taxon-specific as no two species have the same banding pattern. Distant polymorphism in electrophoretic banding patterns of the leaf was observed through a total of forty-one (41) polypeptide bands. Variation existed not only in the number of bands but also in the intensity of bands in the leaf samples studied. The coefficients of similarity range between 0.076 – 0.845. The hierarchical cluster analysis (dendrogram) for the 15 species revealed two major clusters. The first group are Senna spectabilis, S. alata, S. hirsuta, Chamaecrista rotundifolia, C. mimosoides, S. biflora and the second group are S. podocarpa, S. sophera, S. occidentalis, S. obtusifolia, Cassia italica, S. siamea, C. singueana, C. sieberiana and C. fistula. An artificial key for the studied species of subtribe Cassiinae based on their band relationships is also provided. Therefore, the number and intensity of bands are additional characters that can be used for species delimitation in subtribe Cassiinae.","PeriodicalId":34635,"journal":{"name":"Egyptian Academic Journal of Biological Sciences H Botany","volume":"26 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83571535","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 experimental design was a split- plot system with three replicates. The main plots were occupied by the eight rice cultivars “Sakha 101, Sakha102, Sakha105, Sakha106, Giza 177, Giza178, Giza179 and Giza 182”. While, the sub-plots contain four Potassium rates (0, 50, 100and 150% from recommended of K=RDK). Panicle length (cm), number of filled grains/panicle, 1000- grains weight (g), biological, grain, and straw yields (t/ha.), hulling %, milling %, GT%, amylose, grain K content, grain protein content (%) were determined in both seasons. The obtained results revealed that all cultivars were affected significantly regard their respect to K fertilization due to their genetically differed. Moreover, the rice cultivars Giza 178, Sakha 101 and 102 had a significant response with increasing K- fertilizer rate up to 150 from the recommended dose (RDK) as compared with other cultivars under the study","PeriodicalId":34635,"journal":{"name":"Egyptian Academic Journal of Biological Sciences H Botany","volume":"48 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76884029","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}

Methods: The research examined the salinity effect on pharmaceutical Aloe Barbadensis plant; the plant was irrigated with half percent Hoagland nutritional solution containing different rates of Sodium chloride (0, 6, 12 & 18 dS/m) and the plants were harvested in 15 and 45 day intervals. Results:The following morphologic specifications were tested: the plant height, the leaf and root length, the leaf thickness and breadth, the weight of wet shoot and root, the weight of dry shoot and root and the weight of the gel and gel soluble sugars in Aloe vera leaves. In addition, the concentration of Na, K, Cl and Ca of the shoot and root and K/Na and Ca/ Na ratio were examined. Conclusions:One of the most important Aloe Vera's tolerance mechanisms may be the creation of appropriate K/Na , Ca/Na ratio in the shoot in primary time of the tension namely in 15 days and also the salinity rates create many fluctuations on the soluble sugars rates especially glucose and xylose","PeriodicalId":34635,"journal":{"name":"Egyptian Academic Journal of Biological Sciences H Botany","volume":"25 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81275750","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}
