In the current study, we investigated effect of potassium humate (Kh) and salicylic acid (SA) in mitigating salinity stress common bean plants. Common seedlings were treated with 0.2 g/L SA as a foliar application 0.3 Kh soil individually or combination. After 7 days germination, plants 50 mM NaCl normal water control. Our results indicate that salt treatment reduced plant growth (fresh dry shoots roots), leaf pigments (total chlorophyll carotenoids), ascorbic (AA), glutathione (GSH), (K)...
This study aims to explain the effects of silicon on chlorophyll and measure gas exchange carbohydrate levels in two Lycopersicon esculentum cultivars that are exposed drought. The experimental design used this was a randomised combination five different water conditions (control, deficit + 0.00 μmol Si, 0.25 1.00 1.75 Si) applied (Super Marmante Santa Cruz). Parameters measured were exchanges, chlorophylls, total soluble carbohydrates. Silicon at concentrations 0.25, 1.00, induced gradual...
Anthropogenic activities and improper uses of phosphate fertilizers have led to an increase in cadmium concentrations agricultural soils. Brassinosteroids are steroid hormones that rapidly assimilated metabolised with beneficial roles physiological biochemical processes plants. Our aim was ascertain whether exogenous treatment 24-epibrassinolide (EBR) can mitigate the Cd toxicity, this substance reduce accumulation plant tissues. Furthermore, dose response EBR determined following exposure...
The soybean is a legume that widely cultivated in many countries due to the high levels of protein and oil contained its seed, used for human animal nutrition. However, salinity affects more than 800 million hectares worldwide, limiting global agricultural production. aim this research was evaluate structural behaviour roots stems under progressive salt stress, detailing possible anatomical modifications these organs plants during stress. were randomized into five treatments (0, 50, 100, 150...
The aim of this study was (i) to evaluate the impact water deficit and rehydration on nitrogen compounds abscisic acid Vigna unguiculata leaves, (ii) investigate hypothesis that influences proline. experimental design entirely randomized in a factorial design, with 2 conditions (control stress) 7 evaluation periods (0, 1, 2, 3, 4 days under deficit, followed by 5th 6th day rehydration). leaf relative content presented significant reduction, presenting lower value 4th treatment deficit. After...
Drought frequently results in significant losses agricultural systems, including the soybean yield. Brassinosteroids exhibit multiple actions on essential processes, chlorophyll fluorescence and gas exchange. Considering that electron transport rate (ETR) into photosystems can exercise interference net photosynthetic (PN), this research aims to determine whether 24-epibrassinolide (EBR) affects find out if there is any repercussion photosynthesis plants affected by water deficit. The...
Abstract Water deficit is the most limiting abiotic stress to plants because it affects several physiological and biochemical processes. Brassinosteroids, including 24‐epibrassinolide (EBR), are steroids that regulate growth positively act on gas exchange. This research aims determine whether EBR can attenuate negative effects of water deficit, revealing possible contributions this steroid photosynthetic machinery young Eucalyptus urophylla under deficit. The experiment had a completely...
Abstract Salicylic acid (SA) is an interesting messenger in plant metabolism that modulates multiple pathways, including the antioxidant defence pathway, and stimulates anatomical structures essential to carbon dioxide fixation during photosynthetic process. The aim of this research was determine whether pre‐treatment with exogenous SA can alleviate deleterious effects induced by water deficit on production components, biomass gas exchange, measuring reactive oxygen species, enzymes,...
Extreme events of climate change are increasing, such as droughts and heat waves, causing limitations on growth yield in relevant food crops, well threatening global security. Brassinosteroids (BRs) natural or synthetic steroids with significant properties that promote plant development. In the current world scenario, research solutions can improve tolerance to strategic ensure The distinctiveness novelty this review lie its comprehensive detailed approach role BRs plants under biotic...
Soil contamination linked to anthropogenic activities has become a serious environmental problem on global scale. It is caused by heavy metals, such as lead (Pb). Dopamine (DOP) biogenic amine that acts neurotransmitter. found in plant organs and induces tolerance against abiotic stresses, including contamination. 24-epibrassinolide (EBR) stimulates metabolism, positively impacting flowering production. This research aimed evaluate whether EBR DOP, applied alone or combined, can mitigate the...
Plants exhibit several restrictions under waterlogging conditions, including stomatal limitations, negative impacts on gas exchange, lower nutrient uptake and reduced growth. 24-epibrassinolide (EBR) is a polyhydroxylated steroid, with the advantages to be natural biodegradable molecule, presenting beneficial roles in metabolic physiological processes. The aim of this research investigate whether EBR can protect soybean plants against damage caused by evaluate responses associated root leaf...
Several toxic pollutants are released into the atmosphere through human activities. Among these pollutants, lead (Pb) is a non-biodegradable element that can cause reduced cell division, impact negatively on biosynthesis of photosynthetic pigments, and lower biomass accumulation, which to plant death. 24-epibrassinolide (EBR) growth regulator with broad benefits physiological functions biochemical responses, conferring tolerance plants against several biotic abiotic stresses. The experiment...
