Despite the great diversity of plant growth-promoting bacteria (PGPB) with potential to partially replace use N fertilisers in agriculture, few PGPB have been explored for production commercial inoculants, reinforcing importance identifying positive plant-bacteria interactions. Aiming better understand influence inoculation development, two species distant phylogenetic relationship were inoculated maize. Maize seeds Bacillus sp. or Azospirillum brasilense. After germination, plants subjected...
Water deficiency has been recognized as a major abiotic stress that causes losses in maize crops around the world. The crop is very important due to range of products are derived from this plant. A potential way reduce damages caused by water through association with plant growth-promoting bacteria (PGPB) and arbuscular mycorrhizal fungi (AMF). To define mechanisms developed associative PGPB AMF involved protection against moderate drought (MD), study evaluated biometrical, anatomical,...
The recomposition of deforested environments demands the acclimation seedlings in nurseries. This process induces changes physiological, anatomical, and morphological traits plants, favouring their establishment after transplantation to field. present study aimed verify influence full-sun on seedling hardiness. For purpose, leaf gas-exchange, plant anatomical parameters three tree species [Ceiba speciosa (A. St.-Hil.) Ravenna (Malvaceae), Croton floribundus Spreng. (Euphorbiaceae), Cecropia...
The re-composition of deforested environments requires the prior acclimation seedlings to full sun in nurseries. Seedlings can overcome excess light either through pre-existing fully expanded leaves or development new that are acclimated environment. Here, we compared capacity mature (MatL, at time transfer) and newly (NewL, after shift) Guazuma ulmifolia Lam. (Malvaceae) high light. were initially grown under shade then transferred sunlight. MatL NewL used for chlorophyll fluorescence gas...
Light-response curves of seedlings five light-demanding (LD) and four shade-tolerant (ST) neotropical tree species, native to the Brazilian Atlantic biome, were analyzed, aiming verify differences between these functional groups regarding light use. We hypothesized that variations in requirement would occur not only LD ST but also within groups. The apparent quantum yield CO2 assimilation, dark respiration rate (RD), photorespiration (RP), light-compensation point (Icomp), light-saturation...
Abstract Environmental conditions influence the use of different nitrogen (N) sources by plants. We hypothesized that an increase in light intensity favors nitrate (NO 3 − ) relative to ammonium (NH 4 + seedlings neotropical tree species from functional groups, is, Cecropia pachystachya (a shade‐intolerant species), Cariniana estrellensis shade‐tolerant canopy and Guarea kunthiana understory species). analyzed growth N metabolism simultaneously provided with NH NO , under lower (LL) higher...
