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...
The steady increase in cadmium (Cd) levels the environment from anthropogenic actions has contributed to environmental degradation. Virola surinamensis is a forest species that desirable characteristics such as deep and dense roots, relatively rapid growth high biomass production remedy contaminated environments by Cd. aim of this study was assess physiological responses phytoextraction tolerance capacity young plants V. submitted Cd concentrations. experimental design completely randomized...
Sunflower (Helianthus annuus L.) is an important oilseed crop with clear sensibility to salt stress. In this study, we evaluated silicon (Si) effect on the nitrogen metabolism and antioxidant enzyme activity in sunflower plants subjected salinity. A 4 × factorial arrangement of treatments a completely randomized design four replicates was used, consisting concentrations Si (0.0; 1.0; 1.5; 2.0 mM) NaCl (0; 50; 100; 150 nutrient solution. The salinity reduced nitrate content, but increasing...
A deficiência de nitrogênio em hortaliças folhosas, como Acmella oleracea, afeta o crescimento e metabolismo vegetal, impactando negativamente a produtividade. O objetivo deste estudo foi avaliar do desenvolvimento A. oleracea cultivada in vitro sob diferentes concentrações nitrato amônio (NH4NO3). As sementes foram germinadas meio MS com três sacarose (30 g L⁻¹ - T1; 20 – T2; 10 T3) submetidas à análise biométrica após 4 semanas. Não houve diferença significativa nas variáveis biométricas...
The objective of this work was to evaluate the biometric parameters, photosynthetic pigments and antioxidant system Clitoria fairchildiana R.A Howard seedlings subjected exogenous application 5-aminolevulinic acid different concentrations cadmium (Cd). experiment conducted in a greenhouse from May August 2023. Initially, were produced straw seeds. After three months, they transplanted into 3 kg pots containing previously corrected fertilized black soil. Ten days after transplanting, plants...
<title>Abstract</title> The Amazonian species paricá (<italic>Schizolobium parahyba var. amazonicum (Huber ex Ducke) Barneby</italic>) accumulates cadmium (Cd) primarily in the roots, but lack of understanding gene modulation response to this metal and phytohormonal mechanisms complicates its relevance rehabilitation degraded areas.

Objective: Due to this, this study aimed evaluate the behavior of normalized difference vegetation index (NDVI) correlating with leaf biochemical variables Brazilian mahogany (Swietenia macrophylla) under effect increasing doses nickel. Theoretical Framework: Multispectral analyses are a way assess early, efficient, unbiased, and, most importantly, non-destructive responses plants subjected stress. Method: The experimental design used was randomized block (RBD), five treatments (0, 2, 4, 6...
A questão nutricional é considerada um dos principais gargalos na produção agrícola brasileira, conhecer a dose adequada nutrientes fundamental para medidas de manejo. cultura do milho agricultura quando capacidade expressada positivamente sua pode aumentar consideravelmente. O objetivo trabalho foi avaliar o efeito das doses crescente zinco germinação (Zea mays). experimento realizado em sala crescimento com delineamento inteiramente casualizado (DIC), seis tratamentos e cinco repetições,...
O objetivo do estudo foi avaliar os efeitos de doses, fontes e épocas aplicação nitrogênio em cobertura no desenvolvimento plantas milho transgênico cultivado Bioma Amazônia. Os experimentos foram conduzidos município Parauapebas, Pará, duas safras agrícolas (2016/2017 2017/2018). delineamento experimental blocos casualizados, esquema fatorial 5x2x2, constituídos cinco doses N (0; 45; 90; 135; and 180 kg ha-1), nitrogenadas (ureia sulfato amônio) (estádio fenológico V4 V8), com quatro...
O Brasil é o terceiro maior produtor de milho, ficando atrás dos Estados Unidos e China, com 101 milhões toneladas. Devido à alta exigência da cultura por nitrogênio, este macronutriente se tornou essencial para elevar a produtividade do pois possui papel fundamental na síntese proteínas clorofilas. Dessa forma, melhorar estrutura química solo, são usados adubos químicos, que possuem perda volatilização, percolação lixiviação, nitrogenados, tem um custo sua eficiência baixa. Portanto,...
The aim of this study was to economically estimate the effect inoculation with Azospirillum brasilense (A. brasilense) associated enhanced efficiency nitrogen fertilizers on corn yield cultivated in Brazilian Amazon. experimental design used completely randomized, a 2 × 3 5 factorial scheme, resulting from combination presence and absence seeds inoculated A. brasilense, three sources N (conventional urea, urea NBPT, N-(n-butyl)thiophosphoric triamide, polymer-coated urea), five doses (0; 50;...
