Maize Leaf Appearance Rates: A Synthesis From the United States Corn Belt [PDF]
Frontiers in Plant Science, 2022 The relationship between collared leaf number and growing degree days (GDD) is crucial for predicting maize phenology. Biophysical crop models convert GDD accumulation to leaf numbers by using a constant parameter termed phyllochron (°C-day leaf−1) or ...

Alterations in Grapevine Leaf Metabolism Occur Prior to Esca Apoplexy Appearance [PDF]
Molecular Plant-Microbe Interactions, 2017 Esca disease is one of the major grapevine trunk diseases in Europe and the etiology is complex, since several inhabiting fungi are identified to be associated with this disease.

Experimental and modeling evidence of carbon limitation of leaf appearance rate for spring and winter wheat. [PDF]
J Exp Bot, 2019 Carbon availability can account for environmental effects on leaf appearance rate (LAR) and a new ecophysiological model is developed that gives good predictions for LAR in contrasting field environments.

Leaf appearance rate and phyllochron on millet sowing dates
REVISTA BRASILEIRA DE MILHO E SORGO, 2023 The objective of this study was to determine the leaf appearance rate and phyllochron as affected by millet sowing dates. The experiment was conducted with six sowing dates (11/28/2019, 12/03/2019, 12/10/2019, 12/17/2019, 12/30/2019 and 01/14/2020).

Approaches to Modeling Potato Leaf Appearance Rate [PDF]
Agronomy Journal, 2006 Two approaches quantifying potato (Solanum tuberosum L. cv. Kennebec) leaf appearance rates were evaluated: a thermal time approach using the phyllochron, and a nonlinear temperature response approach using a modified β distribution function. Leaf appearance measurements at six temperature treatments (14/10, 17/12, 20/15, 23/18, 28/23, and 34/29°C ...

Spring wheat leaf appearance and temperature: extending the paradigm? [PDF]
Annals of Botany, 2003 Extensive research shows temperature to be the primary environmental factor controlling the phyllochron, or rate of leaf appearance, of wheat (Triticum aestivum L.). Experimental results suggest that soil temperature at crown depth, rather than air temperature above the canopy, would better predict wheat leaf appearance rates.

The Effect of Temperature on Leaf Appearance in Rice [PDF]
Annals of Botany, 1996 Temperature is the principal environmental determinant of crop leaf appearance. The objective of this study is to analyse whether there are different effects of day temperature (TD) and night temperature (TN) on main-stem leaf appearance in rice (Oryza sativaL.).

Modeling of Shoot Elongation and Leaf Appearance in Potted Mulberry [PDF]
Plant Production Science, 2000 To predict mulberry growth, modeling of shoot elongation and leaf appearance of potted mulberries was attempted. Potted mulberries were grown in temperature-controlled phytotrons. Changes in the rates of mulberry shoot elongation and leaf appearance, and
