A wheat canopy model linking leaf area and phenology

open access: yes, 2003
The accurate simulation of leaf area in wheat models is important because leaf area intercepts light and stores nitrogen, and the arrangement of leaves influences the transmission of foliar diseases and inter-species competition. In this paper, we report

Survey of the accuracy and rapidity of several methods for vine leaf area assessment

open access: yesOENO One, 2001
Vine leaf area is an important viticultural parameter. Because its assessment is difficult, leaf area is not frequently taken into account. In this survey, several techniques of vine leaf area estimation are compared for their accuracy and rapidity. Leaf

Understanding and predicting global leaf phenology using satellite observations of vegetation [PDF]

open access: yes, 2013
Leaf phenology refers to the timing of leaf life cycle events and is essential to our understanding of the earth system as it impacts the terrestrial carbon and water cycles and indirectly global climate through changes in surface roughness and albedo.
