Soil water availability and light are abiotic factors that may be plant stressors when they subjected to unfavorable conditions limit their metabolism trigger protection mechanisms. The aim of this study was evaluate morphological metabolic strategies in Cedrela fissilis seedlings enable survival resilience flooding shading. were cultivated under for 0, 10, 20, 30, 40 days or received only rainwater (control: 120 mm distributed over 35 evaluation with a daily maximum 28 mm). Flooding...
Alibertia edulis Rich. is a native species of the Brazilian Cerrado and can be used for reforestation degraded areas. In addition, it produces edible fruits. The objective this study was to evaluate effect substrates water levels on emergence, initial growth, quality seedling A. edulis. tested were: latosol (L), + sand (L S = 1:1), chicken manure S1 CM 1:1:0,5), S2 1:2:0,5), commercial substrate C 1:1); retention capacities (WRC) 25, 50, 75, 100%. experiment carried through in completely...
Abstract The aim of this research was to evaluate the effect abscisic acid (ABA) on gas exchange and activity antioxidant enzymes Ormosia arborea (Vell.) Harms seedlings under water deficit its influence recovery potential seedlings. experiment conducted using four treatments, being daily irrigation or restriction without with 10 μM ABA. Seedlings + ABA showed greater adjustment drought, when re-irrigated, they restored photosynthetic metabolism potential. minimizes reduction in leaf,...
The aluminium at toxic levels causes biochemical and physiological damage that inhibits plant growth limits productivity. Root growth, chlorophyll a fluorescence, enzyme activity of four accessions Jatropha curcas were evaluated under cultivation conditions with different aluminium. experimental design was completely randomized split-split-plot design, in which the plots included soil (0.0, 8.2, 16.5, 24.0 mmolc dm-3), split-plot J. seeds (P1 = Dourados, MS; P2 Montes Claros, MG; P3 Alta...
In this study, we assessed the gas exchange in Caryocar brasiliense seedlings water deficit conditions and their capacity to recover after rehydration. We plant photosynthetic rates, internal carbon concentrations, stomatal conductance, transpiration water-use efficiency, instantaneous carboxylation chlorophyll index, photosystem II quantum efficiency. All parameters were reduced suspension of irrigation. Seedling rates approached zero 12 days. The equilibrium was reestablished all variables...
