Maize Leaf Appearance Rates: A Synthesis From the United States Corn Belt
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 ...

Experimental and modeling evidence of carbon limitation of leaf appearance rate for spring and winter wheat [PDF]
Journal of Experimental Botany, 2019 Accurate predictions of the timing of physiological stages and the development rate are crucial for predicting crop performance under field conditions. Plant development is controlled by the leaf appearance rate (LAR) and our understanding of how LAR responds to environmental factors is still limited.

Modeling of Shoot Elongation and Leaf Appearance in Potted Mulberry
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

BASE GROWTH TEMPERATURE AND PHYLLOCHRON FOR KIKUYU GRASS (Cenchrus clandestinus; Poaceae)
Acta Biológica Colombiana, 2021 In order to estimate the base temperature (Bt) of growth through the appearance of leaves and calculate the phyllochron for kikuyu grass, three plots were established on three farms in the Provincia of Ubaté (Cundinamarca, Colombia) located at different ...

Leaf dynamics of Festulolium and Dactylis glomerata L. at the end of the growing season
Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2008 The paper is focused on the assessment of leaf extension rate (LER), leaf appearance rate (LAR) and leaf senescence rate (LSR) in the Festulolium (Festuca arundinacea Schreb. × Lolium multiflorum Lam.) and in the Dactylis glomerata L.
