Loranthaceae has several complicated taxonomic issues. Six species of Loranthaceae grow naturally in Saudi Arabia, but these species have not been well studied. The aim of this work was to evaluate the importance of morpho-palynological characters as a taxonomic tool in the identification of Loranthaceae species growing in Saudi Arabia. The discriminatory power of these characteristics was evaluated using different statistical analysis methods. The descriptive characteristics of pollen polar and equatorial views and colpus type are useful for describing the species, and the presence of three colpus patterns was detected among the study samples: syn-(3)-, demisyn-(3)-, and zono-(3)-colpate. The quantitative characteristics, specifically, the equatorial diameter and P/E ratio, are the most useful and can be used to classify species within clusters based on their affiliation with genera, species, and subtribes Emelianthinae and Tapinanthinae. This study confirmed that pollen grain characteristics can be used as a taxonomical tool to identify Loranthaceae species. This information will aid in determining parasitic species that infect trees and could be useful for strengthening efforts in weed management.","PeriodicalId":48946,"journal":{"name":"Bioscience Journal","volume":null,"pages":null},"PeriodicalIF":0.5,"publicationDate":"2024-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140993726","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Furthermore, the effects of six commercial chemical fertilizers (inorganic fertilizers and nano-fertilizers) on plant growth and nematode reproduction were also studied. Both cultivars recorded the highest gall formation, embedded stages, and final nematode population at the inoculum dosage of 2,000 J2/plant. The highest reproductive rate was achieved with 500 J2/plant, while the lowest rate was observed with 4,000 J2/plant on both cultivars. ‘Wonderful’, at all M. incognita inoculum levels, was more sensitive to nematode infestation than ‘Manfalouty’. ‘Wonderful’ showed a greater reduction in fresh and dry plant weights than ‘Manfalouty’ at 2,000 and 4,000 J2/plant. In both cultivars, the concentrations of N, P, and K decreased with increasing nematode inoculum levels. This decline was more pronounced in ‘Manfalouty’ than in ‘Wonderful’. The nano-fertilizers, Hyper Feed®, and Hyper Feed Solo® reduced all nematode parameters but only in ‘Wonderful’. Treatment with Hyper Feed® resulted in the highest percentage increases in all plant growth parameters in ‘Wonderful’. Total carbohydrate concentration was increased in ‘Manfalouty’ treated with the nano-fertilizers, especially with Hyper Feed®. Also, concentrations of total phenols and tannins increased in ‘Wonderful’ when treated with either nano-fertilizer. Generally, both nano-fertilizers showed an increase in plant N levels.

This way, the aim was to identify if Brazilian consumers know stingless bee honey and its sensorial characteristics, what is the consumption of this, as well as to generate information to assist in the development of the productive chain of the specie. A closed structured questionnaire with 20 questions was used and the participants were invited via social media. Data were collected in November 2020. The statistical analyses were performed related to the description, characterization of the participants and frequencies. In addition to these,, multivariate analyzes, for word association and questionnaire responses were performed. It is clear that most participants have some confusion between the sensory and physical characteristics of honey from native stingless bees and Apis mellifera. This lack of knowledge of the product can cause problems both in the handling of honey for sale and for consumption. Another interference would be linked to the taste, when we highlight the acidity and less sweetness of this pot-honey, and the consumer can often deduce that the product is damaged or not from a good origin. There is little consumer awareness of the benefits and qualities of stingless honey. Many consumers are still unaware of the differences between breeding sites and characteristics of native stingless bees. Still, a large part of these associates the quality of this honey with the honey of Apis Mellifera.","PeriodicalId":48946,"journal":{"name":"Bioscience Journal","volume":null,"pages":null},"PeriodicalIF":0.5,"publicationDate":"2024-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140996688","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The research was performed at the Vettings laboratory at the State University of Ceará (UECE) with 40 eggs: 20 from commercial and 20 from free-range hens. The eggshells were assessed using the dextrose evaluation method for pathogenic cultivation, commensal, and yeast fungi. Subsequently, readings were taken to identify and count the fungi on a binocular light microscope in 100x increments. Both egg categories showed a significant number of colony-forming units (CFU). The study identified eight different fungal species in both egg production types. The most prevalent fungal colonies in the free-range hen lineage (brown shell) were yeast spp. and Penicillium citrinum, and the laying hen lineage (white shell) had mostly Penicillium spp. and yeast spp. Therefore, both egg production systems showed similar fungal contamination, which suggests that the manipulation and/or storage are adequate despite the lack of strict food safety regulations or supervision for eggs in Brazil.","PeriodicalId":48946,"journal":{"name":"Bioscience Journal","volume":null,"pages":null},"PeriodicalIF":0.5,"publicationDate":"2024-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140997713","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigated the efficacy of three species of coccinellids (Coccinella undecimpunctata, Coccinella septempunctata, and Hippodamia variegata), indigenous to the Taif region of Saudi Arabia, to control Bemisia tabaci whiteflies and Aphis gossypii aphids on cucumbers in greenhouses. The study was conducted with a release rate of five second-instar larvae of each coccinellid species per plant. One week after the first release of coccinellids, there were no significant differences among the treatment groups in terms of infestation rate, but all three groups differed significantly from the control group. After the first week, the B. tabaci and A. gossypii infestation rates decreased significantly in the H. variegata group compared with the other two coccinellid species, a trend that continued until the end of the experiment. These results suggested that H. variegata was the most effective of the three species at decreasing the B. tabaci population. After the second release of each coccinellid species, the reduction rates were >90% in all three groups, being significantly higher in the H. variegata group. Thus, these results suggest that second-instar larvae of all three coccinellid species would be effective predators of B. tabaci and A. gossypii on cucumbers in greenhouses, with those of H. variegata showing the greatest efficacy. Future research should focus on the effects of these predators on outdoor cucumber fields and on other crops grown in the Taif region.","PeriodicalId":48946,"journal":{"name":"Bioscience Journal","volume":null,"pages":null},"PeriodicalIF":0.5,"publicationDate":"2024-05-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140994943","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
