32 Quantification and Modeling Physical Environmental Effects On Plant Processes

Oral Session
A03 Agroclimatology & Agronomic Modeling
The papers in this session address quantitative research on the response of plants to their physical environment. The emphasis is on quantification of the responses of plants to envronmenatal variables such as water, solar radiation, temperature, soil properties and those related to management. Papers on simulation and or process models are included.
