Abstract Amazonian savannas are isolated patches of open habitats found within the extensive matrix tropical forests. There remains limited evidence on how plants from differ in traits related to drought resistance and water loss control. Previous studies have reported several xeromorphic characteristics savanna at leaf branch levels that linked soil, solar radiation, rainfall seasonality. How anatomical features relate plant hydraulic functioning this ecosystem is less known instrumental if...
Plants survive in habitats with limited resource availability and contrasting environments by responding to variation environmental factors through morphophysiological traits related species performance different ecosystems. However, how plant strategies influence the megadiversity of tropical has remained a knowledge gap.We analyzed variations 27 leaves secondary xylem Erythroxylum pulchrum Tapirira guianensis, which have highest absolute dominance these physiognomies occur together areas...
This study aimed to understand the functionality and structural adjustments of wood in a rocky-outcrop plant community an Amazonian savannah by correlating anatomical traits associated with mechanical support water transport. From this, following question was addressed: Can pattern hydraulic architecture most abundant species be traced from functional anatomy their wood? Wood collected through non-destructive method three individuals each dominant species, which processed according standard...
This study represents an important contribution to the structural, histochemical and biological understanding of ducts cavities in leaves four species Calophyllaceae that occur Amazonian savannas. Samples adult were processed using light, scanning transmission electron microscopy, as per usual methods for plant anatomy. In paradermal sections, lumina are elongated while those short. Ducts exclusively central rib abundant Kielmeyera rubriflora Cambess coriacea Mart. Zucc larger than...
Qualea genus is commonly found in different phytophysiognomies of the Brazilian Cerrado, growing open ecosystems to closed forest areas, under high irradiances, fires, low availability nutrients and seasonal water deficit. We compared leaf structural traits grandiflora Mart., multiflora parviflora a cerradão area Cerrado-Amazonian transition. Leaf samples were collected at Mário Viana Municipal Biological Reserve, Nova Xavantina, Mato Grosso state, Brasil, processed according usual...
A alelopatia é o efeito inibitório ou benéfico, direto indireto, de uma planta sobre outra, por meio da produção compostos químicos.Rosmarinus officinalis L. popularmente conhecida como alecrim, utilizada desde a antiguidade.Neste trabalho objetivou-se determinar se os extratos alecrim são alelopáticos à germinação Eruca sativa Foram utilizados dois tipos extratos: seco e fresco.O extrato folhas secas, obtido 10g fervidas 10 minutos em 100ml água destilada.O das frescas não foi fervido sendo...
Savannas of the Amazon Region Mato Grosso State have an unique ecological identity due to complexity Cerrado-Amazon transition region, their geographical isolation and physical-chemical properties soil. This study aimed characterize leaf anatomy Xylopia aromatica, identify potential adaptive traits xeric environment. We collected adult leaves from X. aromatica a Amazonian savannah located in Nova Canãa do Norte city, Grosso. The were fixed stored 70% ethanol. Cross sections obtained by free...
This paper presents additional data on the leaf structural, physiological and nutritional characteristics of three species (Maytenus obtusifolia, Manilkara subsericea e Inga laurina), co-occurring in restinga semideciduous seasonal forest (forest). The were obtained from to identify possible adaptive strategies that could explain co-occurrence these forest. In addition, this can help key functional traits plant community forests be employed reestablishment ecological edaphic processes...
Justicia calycina is a subshrub well distributed in northern South America. Despite its widespread occurrence, little known about anatomy and plasticity different environments. Our study aimed to evaluate how leaf anatomical traits of J. adjust forest areas with variations canopy openness the Southern Amazon, Mato Grosso State, Brazil. Forest were: Open Dense Ombrophilous Forest, Seasonal Deciduous (rocky outcrop). We performed measurements leaves sampled on 10 individuals each site, help...
No presente trabalho foram avaliados os efeitos de diferentes concentracoes Canela ( Cinnamomum zeylanicum) com e sem carvao ativado, no desenvolvimento in vitro protocormios C. x altaflorestense. Foram utilizados altaflorestense obtidos da germinacao sementes em meio cultura alternativo, fitoreguladores, o delineamento experimental foi inteiramente casualizado. Apos 90 dias a partir semente, 5 transferidos para cada frasco capacidade 300 mL, contendo 30 mL cultura. realizadas 25 repeticoes...
As pragas atacam a soja (Glycine max L.) durante todo o ciclo da cultura, principalmente os percevejos, que causam danos aos grãos desde período de enchimento até maturação causando perda na viabilidade.Sabendo qualidade semente reduz com aumento presente trabalho teve objetivo avaliar diferentes populações desses pentatomídeos vários métodos.O experimento foi composto por 5 lotes sementes provenientes cultivos onde variável controle sendo (controle preventivo; 1 percevejo pano batida; 2...
Abstract Amazonian savannas are isolated patches of open habitats found within an extensive matrix tropical rain forest. The climate Amazonia is transitioning to a state that favors over forests. Still, the hydraulic functioning savanna species in vegetation remains unknown and unexplored. We measured 22 leaf, wood, traits, including embolism resistance (as P 50 ) isotope-based water use efficiency (WUE), for seven dominant woody (75% biomass) savanna. wide variation (-1.66 ±0.06 MPa...
