Vines were sprayed in two application times at (25th and 30th August) during 2017 and 2018, respectively. The non-ionic surfactant Tween-20 at 0.05% (v/v) was added to all treatments to reduce the surface tension and increase the contact angle of sprayed droplets. Results showed that both jasmonic acid and grapefruit seed extract treatments at different concentrations were significantly effective in reducing weight loss, berry decay, berry shatter, and total loss in cluster weight percentages during the cold storage period and shelf life as compared to the control. Also, the previous treatments significantly increased berry firmness, soluble solid content (SSC%), SSC/acid ratio, and total anthocyanin contents, where it was caused a significant decrease in total acidity percentage during the cold storage period and shelf life in comparison with control. Furthermore, the lowest values of weight loss, berry shatter, berry decay and total loss in cluster weight were founded by JA at 8 mM and GSE at 1 mM at the end of shelf life in comparison with other treatments. It could be concluded that JA at 8 mM and GSE at 1 mM as preharvest treatments are applicable for improving the storability of ʺCrimson Seedlessʺ grapes and maintaining their quality during cold storage and shelf life.","PeriodicalId":34635,"journal":{"name":"Egyptian Academic Journal of Biological Sciences H Botany","volume":"468 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77935466","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}

This experiment was laid out in a split-plot system with three replications in both seasons. The main plots were soybean varieties (Giza111, Giza 22, J350, and J356), while subplot allocated by the number of spray times of salicylic acid (SA) concentration (water = control, once after 30 DAS, twice after 30, and 50 DAS, and three times after 30, 50 and 70 days after sowing=DAS) was in both seasons. The obtained results showed that foliar application of salicylic acid (SA) of the four soybean varieties significantly affected plant height (cm), number of branches/plant, number of pods/plant, 100- seed weight (g), seed yield (kg/fed), straw yield (kg/fed), biological yield (kg/fed), as well as oil content (%), whereas Giza 111 recorded the highest values of the all the study, also increasing of times of foliar application of SA increased the pervious characters comparing with the control treatments (water spray) in both seasons. The interaction between varieties and number of spray times of SA was significant on all the studied characters, where planting Giza 111 with twice foliar application of SA at the rate 1000 ppm recorded the highest ones in the two cropping seasons in drip water irrigation under the study conditions.","PeriodicalId":34635,"journal":{"name":"Egyptian Academic Journal of Biological Sciences H Botany","volume":"11 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88602582","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}

Ten SSR primer pairs revealed a high percentage of polymorphism (97.4%) among 38 total number of alleles, while 11 SCoT primers produced 48.5% from 171 amplified fragments. SCoTs recorded effective multiplex ratio (EMR) and PIC values of 7.5 and 0.14, respectively, opposing to 3.7 and 0.26 for SSRs, respectively. A similar marker index has thus resulted in both markers. Nei’s gene diversity (h) was generally low for both marker systems indicating homogeneous nature and narrow genetic background for the studied Egyptian date palms, which was also emphasized through their high genetic similarity estimates. The results of UPGMA cluster analysis and PCoA grouped the eleven date palms according to their geographical location and sex. In addition to classical morphological characters, the current study confirmed the importance of using SCoTs as functionally gene-based multi-loci markers besides nuclear SSR loci to assess the genetic variations and cultivar identification among Egyptian date palm genotypes","PeriodicalId":34635,"journal":{"name":"Egyptian Academic Journal of Biological Sciences H Botany","volume":"54 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85466791","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}

Most of indigenous knowledge about plants used for the management of malaria is undocumented and the risks of being lost are on the high. The ethnobotanical study documents the different types of medicinal plants used for the treatment of malaria in Kashere and its environs of Akko L.G.A. of Gombe State. Information was collected by interviewing 84 informants, using a semi-structured questionnaire, which included Traditional Medical Practioneers, farmers and other inhabitants who have experience in the management of malaria. Collected plant samples were identified and authenticated at the Federal University of Kashere Herbarium (FUKH). Data was analysed using frequency and percentages. In this study, 81% of the informants are males and 19% are females. A total of 63% of the informants have attended primary school/Islamia education, and 76% of the respondents are aged above 40 years of age. A total of 41 plants species belonging to 28 families were identified. Most plants used in the management of malaria in Kashere community belong to Fabaceae (12%), Rutaceae (7%), Asteraceae (7%) and Malvaceae (7%) plant families. Azadirachta indica A. Juss is with the highest relative frequency of citation (RFC- 0.74) among the plants surveyed. The main method of preparation is decoction and dominant plant parts used in the preparation of remedies were leaves. The diversity of medicinal plants species used and associated indigenous knowledge are of great value to Kashere community and their conservation and preservation is paramount.","PeriodicalId":34635,"journal":{"name":"Egyptian Academic Journal of Biological Sciences H Botany","volume":"15 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87066871","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}
