O gênero Mentha compreende diversas espécies de interesse econômico por causa da produção óleos essenciais. Recentemente, foram introduzidos no Brasil novos materiais genéticos para avaliação adaptação em relação ao potencial rendimento e composição do óleo essencial. No presente trabalho, comparadas essas características cultivares das x piperita L. (cv. Grapefruit Mint cv. Persian Field), M. suaveolens Ehrh. Hillarys Sweet Lemon Mint), spicata Mentol aquatica Common Mint) arvensis Banana...
O presente trabalho buscou verificar os efeitos da aplicação de diferentes concentrações do ácido indolbutírico (AIB), em talco e solução, no enraizamento estacas caulinares Tibouchina sellowiana (Cham.) Cogn. coletadas nas quatro estações ano, bem como suas variações anatômicas bioquímicas. Estacas semilenhosas foram tratadas com 0, 1500 3000 mg L-1 solução 50% alcoólica. Após 65 dias casa-de-vegetação, avaliados a porcentagem enraizadas, o número comprimento das raízes, calos...
In Rubiaceae, anthraquinones and naphthoquinones are secondary metabolites characteristic of the subfamily Rubioideae, in which Rudgea jasminoides is included. Thin-layer chromatography using specific solvent systems spray reagents indicated presence constitutively produced by cell suspension cultures R. jasminoides. GC/MS analysis detected 1,4-naphthohydroquinone as a product biosynthesis only after elicitation cells with yeast extract (Saccharomyces cerevisiae). The latter compound...
Piptocarpha angustifolia Dusén (Asteraceae) é uma espécie arbórea nativa brasileira pertencente à Floresta Ombrófila Mista, com potencial ambiental para recuperação de ecossistemas e produção madeireira. A propagação seminal desta apresenta dificuldades devido a irregularidade na coleta, aliadas baixa germinação pela formação poucas sementes viáveis. Este trabalho teve como objetivo verificar o enraizamento estacas semilenhosas brotações do ano plantas matrizes adultas, coletadas primavera...
Ligustrum lucidum ait. is an exotic species and In the present study, contents of sugars, proteins, germination were evaluated in seeds removed from not abscisic fruits. The stored or under shadow sun. higher total reducing sugars observed fruit while period storage resulted loss these compounds. same result was content fruits submitted to had its increased. proteins sun significantly different, but results suggested increase protein synthesis during period, differently those that storage....
The genus Mentha has economic importance as a source ofessential oil for food, cosmetic and pharmacy industries. Terpenes arethe main constituents of the essential these species theirbiosynthesis is located in leaf peltate trichome glands. oilyield composition cf. aquatica L., xpiperita L. e arvensis was compared density trichomeglands on zones (abaxial proximal, abaxial middle, distal,adaxial adaxial middle distal) determined. Theexperiment carried out at Center Experimental Station...
Obtaining cells of Physalis pubescens is interest for studies primary and secondary metabolic pathways, in the search new active molecules. Our objectives were to evaluate regeneration potential explants from different parts plant, growth regulators be used, determination curve callus. We used leaf, root, stem petiole, cultured on Murashige Skoog medium with concentrations 6-benzylaminopurine a-naphthaleneacetic acid. The petiole had a higher shoot treatment 0.5 mg L-1 6-benzylaminopurine,...
Background and Objective: In order to improve the Physalis fruit quality, organic fertilization can be a better alternative, once it reduces production costs, recycling wastes produced in rural properties environmental pollution, by avoiding use of mineral fertilizers inappropriate disposal animal wastes.This study aimed evaluate characteristics two species, peruviana L. pubescens L., cultivated different sources nitrogen-mineral fertilizer (poultry litter), under field conditions Southwest...
Although small fruits, with some exceptions, are not yet as popular in Brazil, farmers have invested this market and the genus Physalis can be an important alternative source of income due to its high added value possibility cultivation areas. To date, there no specific fertilizer recommendations for even most cultivated species (Physalis peruviana) therefore goal study was evaluate effects nitrogen fertilization on quality fruits peruviana pubescens. Plants were grown 5 L pots containing...
The cultivation of small fruits has been increasing with good economic returns, and among these, the genus Physalis an important alternative source income due to high value possibility in areas. However, there is not established fertilization for this crop considering that nitrogen one most limiting nutrients growth development plants, study aimed evaluate agronomic aspects two species submitted different N doses. experiment was conducted a greenhouse completely randomized design, using...
Abstract Early-ripening peach cultivars present difficulties in the process of natural germination seeds. In order to solve this problem, culture embryos vitro can be considered an alternative, which seeds find conditions complete and development a satisfactory way. Different protocols media have been tested meet nutritional needs embryo, but they still problems need optimized. The objective work was test BAP concentrations increase percentage viable ‘BRS Kampai’ seedlings, avoiding possible...
The plant spacing and ridging are essential practices for the cultivation of potato.The study was conducted in experimental area Department Agronomy, Universidade Estadual do Centro Oeste -Unicentro, Guarapuava -PR.The objective to evaluate effects different row crop time on yield characteristics potato tubers.The experiment structured a randomized block designinfactorial 4 x with four replications, consisting managements / times ridging, being one witness without plants from 16 34 cm that...
Rudgea jasminoides (Cham.) Müll. Arg. é uma rubiácea arbórea nativa da floresta tropical que sintetiza metabólitos secundários antifúngicos, quando em contato com fungos. Membros família Rubiaceae estão entre as poucas plantas facilmente mantidas cultura de tecidos e produzem quantidades substanciais ultrapassam os níveis normalmente encontrados na planta intacta. Neste trabalho foi analisada a presença compostos antifúngicos constitutivos induzidos produzidos por folhas suspensões celulares...
Physalis cultivation can be an alternative of extra income for small and medium producers, mainly with the use materials available on property that replace chemical fertilizer. This study aimed to evaluate agronomic parameters peruviana P. pubescens submitted two different sources fertilization - organic. We evaluated plant height, shoot dry mass, production/plant, fruits diameter weight productivity. The organic provided better results vegetative parameters. Regarding production, resulted...
The effects of foliar application Mo and use N from cover crops (Crotalaria juncea L. Canavalia ensiformis (L.) DC) on the performance common beans were investigated in this study. Field experiments carried out a succession planting system (cover - beans), nitrate reductase activities evaluated laboratory. production was done 2 x 4 factorial scheme installed random blocks with four replications. two sunn hemp jack bean composed first factor molibdenum doses (0, 40, 80, 120 g ha-1) second....
Las bayas Physalis, de la familia Solanaceae, han alcanzado una gran aceptación en todo el mundo debido al sabor fruta y su posible uso medicinal.
