A aplicação precoce de nitrogênio em cobertura não aumenta o rendimento de grãos do trigo cultivado na presença do alumínio Early nitrogen side - dress application does not increase wheat grain yield at the aluminum presence

Ciência Rural, 2008
A época de realização da adubação nitrogenada de cobertura pode interferir sobre a participação dos afilhos no rendimento de grãos do trigo em solos ácidos.

Elevated atmospheric CO2 concentration triggers redistribution of nitrogen to promote tillering in rice

Plant-Environment Interactions, 2021
Elevated atmospheric CO2 concentration (eCO2) often reduces nitrogen (N) content in rice plants and stimulates tillering. However, there is a general consensus that reduced N would constrain rice tillering.

Tillering behavior in Oryza sativa L. VI. The tillering behavior at late tillering stage.

Japanese Journal of Crop Science, 1989
The tillering behavior of rice plants (1 plant/pot) at the late tillering stage was investigated. Assuming plant growth in which a leaf of each tiller and a leaf of the main stem expand synchronously (synchronous growth), we made a growth curve of tiller number which we called a 'synchronous growth curve (SGC).

Exogenous Hormonal Application Regulates the Occurrence of Wheat Tillers by Changing Endogenous Hormones

Frontiers in Plant Science, 2018
Plant hormones play important roles in regulating the occurrence of crop tillers. However, little is known about the relationships and the underlying mechanisms between endogenous hormones and the occurrence of wheat tillers induced by exogenous hormones.

Development of axillary shoot in tillering and no-tillering maize plants.

Japanese Journal of Crop Science, 1987
Development of all axillary shoots was investigated using tillering cultivars (delegated by cv. Longfellow) and no-tillering cultivars (delegated by cv. Yellow Dent) in maize. There was a buttress or axillary bud with only prophyll at the axil just above the topmost fertile ear node in both cultivars (Figs. 1, 2), but this did not develop any more (Fig.

Bootstrap Approximation to Prediction MSE for State-Space Models with Estimated Parameters

, 2004
We propose a simple but general bootstrap method for estimating the Prediction Mean Square Error (PMSE) of the state vector predictors when the unknown model parameters are estimated from the observed series.

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

FEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.
