We investigated whether there were consistent differences in the physiological and anatomical traits phenotypic variability of an invasive (Prosopis juliflora (Sw.) DC.) native species (Anadenanthera colubrina (Vell.) Brenan) response to seasonality a tropical dry forest. The water potential, organic solutes, gas exchange, enzymes antioxidant system, products oxidative stress parameters evaluated both seasonality. An analysis responses indicated that P. exhibited higher net photosynthetic...
The effects of water deficit on physiological and biochemical variables young plants two tropical woody species, Pachira aquatica Sterculia foetida, their recovery abilities were measured. Leaf potential, gas exchange selected carbon metabolism components measured in a greenhouse experiment with control, moderate severe treatments. Under drought stress, chlorophyll fluorescence decreased both species compared to respective controls. After rehydration, P. S. foetida showed partial full the...
The main goal of this study was to evaluate the performance two palm species under semi-arid conditions during rainy and dry periods: native Syagrus coronata a tropical America, Acrocomia aculeata. leaf water potential, gas exchange, soluble sugars, starch, free amino acids, total protein content morphological traits were measured. highest potential CO2 assimilation values in both achieved period. In response low soil moisture period, exchange decreased 72 92% S. A. aculeata, respectively,...
Epicuticular waxes (EW) are important for plant physiology as a protective barrier against water loss. Thus, the main goal of this study was to evaluate ecophysiological performance Cynophalla flexuosa, an evergreen woody species, under different foliar EW contents. The conducted during three periods throughout year in seasonally dry tropical forest area. xylem potential decreased 70% at midday. components were n-alkane chains, effective keeping cuticle impermeability. We analyzed intact...
During storage, infestation by insect pests occurs, causing quantitative and qualitative losses in grains, which requires the control of these insects with phosphine gas. Rice husk has a high adsorption capacity, influencing gas concentration during fumigation potentially leading to inefficient fumigation. Additionally, sorption rice results higher residue grain. Therefore, objective this study was evaluate husk, paddy rice, brown as well industrial quality (head yield, rehydration cooking...
Justificativa/Problema: A malária representa um grave problema de saúde pública no mundo, com alta morbimortabidade Brasil, principalmente na Amazônia Brasileira. Investigar a incidência desta doença nos estados extra-Amazonia é fundamental importância para os programas erradiacação da doença. Objetivo: Este trabalho investigou o perfil casos autóctones estado do Rio Janeiro. Métodos: Trata-se uma revisão sistemática e as recomendações protocolo PRISMA foram seguidas. As buscas realizadas...
This study aimed to evaluate the leaf primary metabolism in two woody species, Sterculia foetida and Bombacopsis glabra. Both species have seeds rich oil they are largely found regions with irregularities water availability. Seedlings were grown a greenhouse from seeds. At 140 days after emergence, 50% of plants subjected salt stress for 23 days, daily receiving 100 mM NaCl solution. In both stomata conductance potential decreased quickly under stress. The showed different strategies...
Studies addressing the physiological and anatomical responses of plants under different light intensities normally are performed in short term. Thus, present study includes a long term analysis. This aims to verify whether phenotypic variability off attributes two woody tropical specieis, Paquira aquatica Sterculia foetida, compatible both exposure availability levels (full-light half-light local irradiance) long-term same conditions. The was developed phases: phase I (short term) II (long...
The need to increase the product's shelf life and growing concern minimize use of synthetic products encouraged researchers evaluate antioxidant activity quantify phenolic compounds as chlorogenic acid, caffeic rutin, quercetin apigenin through HPLC, in 29 accesses Capsicum baccatum.Capsicum baccatum var.pendulum is one species genus widely consumed Brazil.It second largest pepper produced world.However, its chemical composition mainly extract have been poorly reported literature.In order...
