Sesbania virgata (Cav.) Pers. is a bush, pioneer and occurs naturally in Brazil. It belongs to the Fabaceae family it indicated for recovery of degraded areas because its rusticity capacity tolerate flooding. The present research was carried out investigate ability S. plants adapt flooding conditions. Plants containing six expanded leaves were placed masonry tanks subjected following conditions: control (well watered), soil-waterlogging (water setup level 1 cm above soil surface – roots...
Effect of nitric oxide (NO) in mitigating stress induced by arsenic (As) was assessed Pistia stratiotes, with NO supplied as sodium nitroprusside (SNP). Plants were exposed to four treatments: control, SNP (0.1 mg L−1), As (1.5 + and 0.1 for seven days (analyses growth, absorption mineral nutrients) 24 h concentration reactive oxygen intermediates (ROIs), antioxidant capacity photosynthesis). P. stratiotes accumulated high concentrations this accumulation wasn't affected the addition SNP,...
Water deficit is a major environmental constraint on crop productivity and performance nitric oxide (NO) an important signaling molecule associated with many biochemical physiological processes in plants under stressful conditions. This study aims to test the hypothesis that leaf spraying of S-nitrosoglutathione (GSNO), NO donor, improves antioxidant defense both roots leaves sugarcane water deficit, positive consequences for photosynthesis. In addition, roles key photosynthetic enzymes...
The free radical nitric oxide (NO) is a signaling molecule that controls several important physiological and pathophysiological processes in mammals plants. In humans, the biological impacts of NO include, but are not limited to, key roles cardiovascular, neurological, immunological, respiratory, reproductive systems. plants, modulates plant growth development with defense against biotic abiotic stress conditions. However, administration exogenous donors still faces limitations, mainly due...
Arsenic (As) is the one of main environmental pollutant and phytoremediation an effective tool for its removal environment.In this study, Pistia stratiotes were exposed to seven As concentrations (0, 3, 7, 10, 13, 16 20 µM) then, influence metalloid on growth, mineral nutrition photosynthesis analyzed.It was observed that species have a high affinity uptake occurs rapidly.The Cu, Mn, Fe P increased until concentration 13 µM, decreasing in higher concentrations.The Mg content also decreased...
Drought stress can imprint marks in plants after a previous exposure, leading to plant acclimation and permissive state that facilitates more effective response subsequent events. Such imprints would benefit obtained through vegetative propagation (propagules). Herein, our hypothesis was the propagules from previously exposed water deficit perform better under as compared those did not face stressful conditions. Sugarcane were grown well-hydrated conditions or subjected three cycles of by...
Nitric oxide (NO) is an important signaling molecule associated with many biochemical and physiological processes in plants under stressful conditions. Nitrate reductase (NR) not only mediates the reduction of NO3ˉ to NO2ˉ but also reduces NO, a relevant pathway for NO production higher plants. Herein, we hypothesized that sugarcane supplied more as source N would produce water deficit. Such reduce oxidative damage favor photosynthetic metabolism growth limiting Sugarcane were grown nutrient...
Enhancing crop yield through improved photosynthesis is a key for feeding the global population and providing feedstock sustainable green economy. However, effectively linking photosynthetic performance biomass production in C 4 species requires an integrative approach at plant canopy. This study aimed to characterize along canopy of five maize (BM3069-PRO2, AG8701-PRO4, K7500-VIP3, DKB355-PRO3 B2401-PWU) sorghum (DKB560, Enforcer, IAC 7021, Brandelisa Santa Elisa) cultivars, focusing on...
Coffee (Coffea arabica) plants show a positive relationship between stomatal closure and formation accumulation of H2O2. However, for coffee under water restriction such has never been studied. The objective the present study was evaluate movement antioxidant capacity seedlings different regimes. Eight months old cv. Catuaí IAC 99 were submitted to field capacity, gradual total suspension irrigation during period 21 days. Evaluations leaf potential (Ψw) performed in beginning morning,...
Agaves have been a valuable resource in dryland areas for centuries, providing fibers (sisal), food, and beverages. However, the advent of synthetic has led to decrease research on Agave , resulting cessation breeding programs Brazil. With rise climate change, there is renewed interest its potential as biofuel feedstock semiarid regions. Since 2016, we collecting accessions throughout country retrieving what left Brazil’s original program establish new germplasm bank. Here, evaluated 21...
Plantas em seu ambiente natural estão sujeitas a condições adversas, passando por períodos de estresse breves ou duradouros. Algumas espécies desenvolvem mecanismos que as fazem suportar permitindo sua sobrevivência. O objetivo deste estudo foi avaliar respostas fisiológicas e anatômicas no desenvolvimento inicial plantas sibipiruna submetidas à hipoxia. com três quatro folhas completamente expandidas foram tratamentos: sem alagamento, alagadas nas raízes totalmente alagadas. Foram...
This study aimed to test the hypothesis that increases in leaf nitrogen concentration would reduce sensitivity of sugarcane photosynthesis low temperature. IACSP95-5000 plants were grown inside a growth chamber at 30/20oC (day/night) and we evaluated effects spraying (2.5% urea) on facing temperature (22/12°C) for eight days. The supply increased exhibited higher gas exchange as compared nonsprayed ones. We also found activity carboxylation enzymes, Rubisco phosphoenolpyruvate carboxylase,...
