<title>RESUMO</title><p>Objetivou-se, com trabalho, avaliar a pós-colheita de clones cacaueiros produzidos na região litorânea do norte Espírito Santo, quanto às características físicas e químicas seus frutos. As caracterizações foram realizadas partir 10 frutos referentes sete cacau (CCN 10, CCN 51, CEPEC 2002, PH 15, 16, OS 1319 TSH 1188). Foram avaliados o peso total, diâmetro comprimento fruto, da casca, espessura sulco mais espessa número, seco, largura, das amêndoas,...
Resíduos de sulfentrazone podem permanecer no solo por cerca dois anos, oferecendo risco contaminação a lençóis freáticos e impossibilitando o cultivo espécies susceptíveis. Diante disto, fitorremediação pode representar uma opção para descontaminação áreas que sofreram com intensas aplicações deste herbicida. O presente trabalho avaliou potencial remediador das Crotalaria juncea, Canavalia ensiformis, Cajanus cajan (anão), relação ao herbicida sulfentrazone, utilizando-se milheto...
Dentre as novas tecnologias, a fitorremediação é opção para descontaminação de áreas que receberam intensas aplicações herbicidas. Este trabalho foi desenvolvido com o objetivo selecionar espécies potencial solos contaminados herbicida sulfentrazone. As testadas foram: Calopogonium mucunoides, híbrido sorgo (Sorghum bicolor x Sorghum sudanense), Crotalaria breviflora, juncea, Canavalia ensiformis, Dolichos lablab, Stizolobium deeringianum e aterrimum, cultivadas em cinco doses do...
A fitorremediação é uma alternativa para a descontaminação de áreas que receberam intensas aplicações herbicidas. Determinar o período mínimo as espécies devem permanecer remediando solo fundamental otimização das serem cultivadas sem riscos carryover. Objetivou-se com este trabalho avaliar tempo cultivo Canavalia ensiformis em solos contaminados herbicida sulfentrazone, modo essa espécie remedie níveis satisfatórios. O experimento foi instalado casa vegetação, utilizando-se vasos 10 dm3; e...
Somatic embryogenesis from explants hermaphrodite papaya mother plants is an alternative for the production of true-to-type without need sexing. This study aimed to analyze hormonal and osmotic inducers in different somatic stages commercial hybrid UENF/Caliman 01. Leaf disks vitro shoots originated ex were cultured induction medium supplemented with concentrations 2,4-D (6, 9, 12, 15, 18 μM) 4-CPA (19, 22, 25, 28, 31 μM). After 90 days, formation embryos was verified. The induced light...
RESUMO: Diante das novas tecnologias, a fitorremediação apresenta-se como opção para descontaminação de áreas que sofreram com intensas aplicações herbicidas.O presente trabalho teve objetivo avaliar o potencial remediador espécies adubos verdes crotalária-júncea (Crotalaria juncea L.), feijão-de-porco (Canavalia ensiformis (L.) DC.), feijão-guandu (Cajanus cajan L.) e feijão-guandu-anão (anão) L. Millsp.)ao herbicida sulfentrazone.Foi utilizada espécie mucuna-anã (Stizolobium deeringianum...
This study evaluated the effect of osmoregulators and carbohydrates on maturation germination somatic embryos papaya ‘Golden THB’. Cotyledon explants from seedlings germinated in vitro basal MS medium were cultured embryogenesis induction (IM) containing salts, myo-inositol, sucrose, agar p-chlorophenoxyacetic acid. After 50 days, embryogenic calli transferred onto media (MM) for 45 additional days. For experiment 1, a MS-based supplemented with abscisic acid, activated charcoal...
This study aimed to evaluate the herbicidal activity of picloram on biomass remediation plants Eleusine coracana and Panicum maximum after cultivation in a soil contaminated with this herbicide. These species were grown three soils, differentiated based texture (clayish, middle, sandy, 460, 250, 40 g kg(-1) clay, respectively), previously (0, 80, 160 ha(-1)). After 90 days, harvested an extract was produced by maceration leaves stems these plants. It applied pots containing washed sand,...
ABSTRACT Shaded coffee systems may offer a series of benefits, however, studies on shaded cultivation Conilon crops are still scarce in the literature. This study aimed to evaluate soil physical, chemical, and biological properties two intercropping from southeastern Brazil. Two commercial – one by macadamia trees other green dwarf coconut were evaluated according three treatments: plants inter-row tree species; same row trees; unshaded coffee. The experimental design was completely...
The quality of the root system in stem cuttings Piper nigrum is highly associated with induction adventitious roots by means auxins and type substrates.The objective this study was to evaluate rooting P. cv.Bragantina treated or not indole-3-butyric acid (IBA) different experiment conducted a randomized block design following factorial 2 x 11 scheme (IBA -0 4000 mg kg -1 talc substrates), four repetitions 16 each.The auxin increased improved system.The substrates evaluated presented diverse...
The soil in the production of clonal seedlings black pepper (Piper nigrum L.) contributes to fusarium and nematodes infestation commercial crops, thus usage alternative substrates might be a preventive control measure against these pathogens. aim this study was investigate rhizogenic behavior cultivars Bragantina, Iaçará Guajarina different substrates. experimental design randomized blocks 3x4 factorial (cultivars: x substrates: + organic compound (18%), vermiculite, carbonized rice hulls...
