I am attempting to organize a session entitled "Simulating phenotypic 

plasticity to the environment" for the upcoming American Society of 

Agronomy meetings to be held in Pittsburgh, PA, 1-5 November 2009. This 

session will be part of the A03 Agroclimatology and Agronomic Modeling 

division presentations. Phenotypic plasticity can be defined as “the 

ability of a genotype to produce distinct phenotypes when exposed to 

different environments throughout its ontogeny”. I believe that 

quantifying phenotypic plasticity will provide new insights into the 

simulation of crop related processes resulting in improved simulations. As 

with many things in life, easy to say, but hard to accomplish. A question, 

are “genetic coefficients” constant or are they a function of the 

environment? If you would like to present a paper or a poster in this 

session or have a question, please let me know. Unfortunately, there are 

no funds available to support travel to this meeting. Thanks.
