Changes in plant metabolism due to water deficit combined with other stresses, such as high irradiance and temperatures, cause damage the physiology development of crops, which can lead significant yield losses. The aim this study was determine potential potassium phosphite (PP) induce tolerance soybean plants. experiment carried out an acclimatized growth chamber. Soybean plants, upon reaching R1 developmental stage, received following treatments: PP application (0 L ha−1–control; 0.6 ha−1...
ABSTRACT Drought is the most harmful environmental factor crop productivity. Some chemicals are used in agriculture to mitigate damage from this stress on plants. Therefore, we examined whether spraying of zinc sulfate (ZS), potassium phosphite (KPhi) and hydrogen sulfide (H2S) donor sodium hydrosulfide (NaHS) would deleterious effects water deficit sunflower plants by analyzing physiological biometric characteristics. The experiment was carried out a greenhouse using randomized block design...
In Brazil, the expansion of agricultural activity and associated indiscriminate use herbicides such as glyphosate is directly related to loss biodiversity in Cerrado. The identification plant species bioindicators herbicide action, especially native area, can help monitoring impacts xenobiotics remaining Thus, this study was designed evaluate possible Cerrado Pouteria torta a bioindicator action via changes physiological performance. At 16 months after sowing, effect evaluated by applying...
The maturing of drift used in the culture sugar cane can have harmful effects on other crops grown vicinity plantations. Among these, sunflower off-season its growth and productivity affected by drift. objective this research was to evaluate whether trinexapac-ethyl glyphosate promotes changes photosynthetic metabolism plants. Two trials were carried out these products gas exchange, chlorophyll fluorescence, chloroplastid pigments, membrane permeability, content, as well shikimic acid...
Soybean is one of the most economically important crops and has experienced adverse physiological biochemical effects when subjected to drought stress heat, resulting in lost productivity. Thus, objective this work was evaluate physiological, metabolic growth responses well-watered drought-treated soybean cultivars under high temperature. The experimental design set up randomized blocks, a factorial scheme with three (7739 M, Anta 82 Desafio) two water levels (100% 40% field capacity)....
Abstract Little is known about the role of light intensity in modulating plant responses to stress due water deficit (WD). Thus, objective this study was determine WD and contrasting irradiance effects on physiology, anatomy, grain yield soybean plants. The experimental design a randomized block growth chamber 2 × factorial treatment arrangement: 90% (well‐watered, WW) 40% (WD) soil field capacities (FC); 750 (medium irradiance, MI) 1500 (higher HI) μmol (photons) m −2 s −1 irradiance....
Raphanus sativus L. and Crambe abyssinica Hochst.are promising crops for supplying oil to chemical industries.They are not used human consumption can be grown off-season due their short life cycle.However, drought may limit growth, photosynthesis productivity.Thus, the aim of this research was evaluate morphological physiological responses R. C. subjected water deficit identify strategies by these species tolerate effects stress.Two independent experiments were conducted with different...
Abstract The economic basis of the Brazilian midwest is agriculture, concentrating most grain production in country. With purpose increasing yield, farmers have intensified land use and atrazine among other pesticides, which can supposedly compromise human health photosynthetic metabolism plant species from Cerrado, such as Handroanthus heptaphyllus . aim this study was to determine experimentally sensitivity level H. atrazine, by measuring gas exchange, chlorophyll a fluorescence,...
O uso de herbicidas é essencial para o controle plantas daninhas e aumento da produtividade das culturas, porém esses produtos podem afetar a fisiologia crescimento organismos não alvos, incluindo nativas. Nesta pesquisa, objetivou-se avaliar em casa vegetação climatizada as trocas gasosas, fluorescência clorofila teor pigmentos cloroplastídicos pequi (Caryocar brasiliense) tratadas com glyphosate. Os tratamentos, arranjados blocos casualizados, corresponderam doses 0 (controle), 50, 100,...
Biodiversity in the Brazilian Cerrado biome has been declining sharply with continued expansion of agriculture and excessive use herbicides. Thus, aim this study was to evaluate morphophysiological biochemical responses Dipteryx alata plants various doses herbicide 2,4-D. Specific biomarkers that characterize phytoindicator potential species were determined. Gas exchange, chlorophyll a fluorescence, photosynthetic pigments, activities antioxidant enzymes cellulase performed after 24, 96...
Raphanus sativus L. is a potential source of raw material for biodiesel fuel due to the high oil content in its grains. In Brazil, this species cultivated low rainfall off-season, which limits productivity crop. The present study investigated effects water restriction on physiological and biochemical responses, production components, quality R. at different development stages. treatments consisted 100% replacement (control), 66%, 33% field capacity during phenological stages vegetative...
ABSTRACT Some forages release allelopathic substances into the environment, and may prevent consortium with arboreal species in pastures. The objective of this work was to evaluate photosynthetic characteristics pequizeiro plants (hereafter pequi) influenced by concentrations residues forage Urocholoa decumbens, Melinis minutiflora Paspalum notatum. treatments consisted pequi cultivation under aerial three mixed substrate four (1, 2, 3 4% mass/mass), plus an additional treatment (comparative...
The objective of this study was to evaluate the responses Raphanus sativus application herbicide tepraloxydim by analyzing photosynthetic and biometric characteristics plants. experiment conducted in a greenhouse treatments were instituted when plants had five expanded leaves. applied at doses 0, 75, 100, 125 g active ingredient per hectare (g a.i. ha-1). dose ha-1 led small decrease rate, water use efficiency, effective quantum yield PSII, rate electron transport, concentration...
ABSTRACT: Pequi plants are native fruit species of the Cerrado and is at risk extinction due to destruction vegetation extraction their fruits. Because this has a long juvenile period, it becomes susceptible interference weeds, mainly forage grass. This research aimed evaluate effects grass coexisting with small seedlings. The treatments, arranged in factorial scheme, consisted three weed species(Melinis minutiflora, Paspalum notatumandUrochloa decumbens)coexisting four densities (1, 2, 3, 4...
