Daylength change and leaf appearance in winter wheat
Plant, Cell and Environment, 1980Abstract In the field successive leaves of winter wheat appear at a rate which varies because it depends strongly upon temperature. When plotted against ‘thermal time’, however (temperature accumulated above a fixed base of 0°C), leaf appearance was a strictly linear function of temperature.

Interaction of temperature and daylength on leaf appearance rate in wheat and barley
Agricultural and Forest Meteorology, 1998A common way of describing wheat phenology during the leaf development stage is by reporting the number of leaves on the main stem. The ability to predict the timing of successive leaf appearance is important because it impacts on the timing of certain developmental stages of the plant and on the rate of leaf area expansion. Therefore, most crop models

Base Temperatures for Budbreak and Leaf Appearance of Grapevines
American Journal of Enology and Viticulture, 1989Cuttings from 10 cultivars of Vitis vinifera L., one of Vitis labrusca , and one French hybrid were taken, after cessation of winter dormancy, from six vineyards into seven controlled temperature regimes with day/night temperatures of 10/5°C to 30/25°C ...

Response of white clover (Trifolium repens L.) leaf area to water deficit depends on three processes: individual leaf expansion, phytomer production, and stolon branching. We have evaluated these processes in five clones under a wide range of conditions.

Effect of Temperature on Time to Panicle Initiation and Leaf Appearance in Sorghum
Crop Science, 1998Leaf‐tip appearance and duration from planting to panicle initiation (PI) are important developmental processes in cereals. This study was conducted to determine the effect of air temperature on rates of leaf‐tip appearance and 1/PI for sorghum [Sorghum bicolor (L.) Moench].

Rate of Leaf Appearance in Crimson Clover
Crop Science, 2002Understanding factors that affect growth and development of crimson clover ( Trifolium incarnatum L.) are important for the development of management practices to optimize forage utilization. In a 3‐yr field experiment at College Station, TX, we evaluated the effects of planting date on rate ...

Floral initiation, leaf initiation and leaf appearance in sunflower
Field Crops Research, 1993Abstract This paper examines the hypothesis that leaf number visible at floral initiation (LN n ) and final leaf number (FLN) are correlated in sunflower ( Helianthus annuus L.). The relationship between these variables is described by a model that takes into account the rate of leaf primordium initiation (RPI), the rate of leaf appearance (RLA) and
