The objective of this study was to identify the diversity of use of food and medicinal plants by the Brejal rural community in Rio de Janeiro state, Brazil. Ethnobotanical data was obtained using the snowball technique and semi-structured interviews with 22 farmers. Species diversity and use-value indices were calculated. Relationships among the numbers of plants cited, interviewee age, gender, and working time in agriculture were investigated. We identified a high diversity index, comprising 185 species belonging to 53 botanical families, notably Asteraceae, Lamiaceae, and Brassicaceae. The greatest use-values were associated with exotic species. Leaves were the plant structures most utilized, and infusions the predominant method of preparation. The prescriptions most commonly cited related to illnesses of the digestive system. Men and women did not differ in terms of the numbers of species cited. We found no correlations between the ages of the interviewees and their working time in agriculture. The uniformity of the number of citations demonstrates the shared knowledge throughout the community, covering a high diversity of plants, uses, indications and preparations.","PeriodicalId":38672,"journal":{"name":"Rodriguesia","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67285348","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 sense, studies that aim to promote the success of the process are necessary. Therefore, the objective of this work was to analyze the effects of initial fresh mass and fertilization on the propagation of two species of Rhipsalis, thus ensuring their success after relocation to a protected area. Therefore, fertilized and unfertilized plants of Rhipsalis puniceodiscus and Rhipsalis trigona initially with one or two cladodes were propagated in a greenhouse for 25 months. After relocation to a forest area, their survival was monitored for 16 months. Survival percentage, shoot length and root length were analyzed every four months. Fresh mass, dry mass and photosynthetic pigment were analyzed before relocating to a native forest. During the protected propagation stage, for both species, individuals presenting more branches and those that were fertilized exhibited more intense overall development. The propagation of R. puniceodiscus and R. trigona in a greenhouse with two cladodes is better than with one cladode. In general, R. puniceodiscus displayed better development under controlled conditions than R. trigona. Propagation using fertilization increased fresh mass and favors growth and survival rate of R. puniceodiscus and R. trigona. It is possible to relocate both species to a preserved area of the Atlantic Forest, but R. trigona presented more potential.","PeriodicalId":38672,"journal":{"name":"Rodriguesia","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67285227","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}

These chemicals cause undesirable changes in ecosystems, particularly the contamination of non-target native forest species through drift. The nuisances caused by pesticides go beyond environmental damage and include public health problems. The objective of this work was to evaluate the effects of glyphosate on leaf gas exchange, photosynthetic pigments and morphoanatomy of seedlings of Eugenia dysenterica. The visual toxicity, physiological and morphoanatomical characteristics of E. dysenterica, when exposed to concentrations of 0, 550, 1110 and 2220 g a.e. ha-1 of glyphosate, were analyzed. The results indicate that the herbicide caused toxicity in the leaves in all treatments. Reductions in photosynthesis (A), stomatal conductance (gs), and transpiration (E) at 47 DAA, were also identified. Glyphosate caused damage to the anatomical structures of E. dysenterica leaves. From the data analyzed it is possible to affirm that plants of E. dysenterica are sensitive to the action of glyphosate. Visible symptoms such as chlorosis and necrosis in the leaf edge are indicators that can be used by rural communities as a warning of the risk of contamination.","PeriodicalId":38672,"journal":{"name":"Rodriguesia","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67285267","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 genus has been studied in different areas of science. However, some questions remain unanswered after the new circumscription as proposed by phylogenetic studies. Here, I review different aspects related to the reproductive biology of Piper species (phenology, sexual expression, floral biology, pollination and mating systems), comparing the results between Neotropical (representing most of the studies carried out so far) and Paleotropical regions. Seventy-five species were analyzed. Some patterns can be observed, mainly in Neotropical species, such as the predominance of annual flowering and fruiting, dichogamy (generally incomplete protogyny) with gradual and sequential exposure of stigmas, asynchronous pollen release, and pollination by insects. Some aspects have been poorly studied, such as variations in sexual expression, the efficiency of different pollinators, and the chemical composition of floral volatiles associated with their role in pollination. In addition, I discuss remaining gaps and further studies that are required, mainly on Paleotropical Piper species, to obtain basic information on the reproductive biology of these plants. From this, comparisons with Neotropical species can be made, allowing the verification of patterns in this genus.","PeriodicalId":38672,"journal":{"name":"Rodriguesia","volume":"76 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67285059","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}

Many species are economically important as a source of food, spices, medicines, and ornamental plants. This study aims to elucidate the floral morphology of E. elatior and understand the behavior of the set of stamen and style during floral anthesis, seeking to identify the mechanisms that promote xenogamy in the species. Flower morphology, time of anthesis and movement of the stamen and style during this period, pollen viability, nectar volume, floral visitors, and the reproductive system were evaluated. The flowers of E. elatior exhibited synchronous movement of the style and stamen, however, this movement was not considered as flexistyly, since the species does not present dichogamy. The synchronous movement of the stamen and pistil, by itself, was not enough to promote self-pollination. Fruiting depends on pollinators. The stigma fluid is an important means whereby pollen adheres to the mouthpart of the pollinator. Hummingbirds and bees were considered the most effective pollinators of E. elatior in the area studied.","PeriodicalId":38672,"journal":{"name":"Rodriguesia","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67285090","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}
