Don't you think a caution is warrented with regarded to 
the APAR productivity relationship?  In Larcher's most recent text, there 
is an excellent graph of total photosynthesis vs. productivity and there 
are four separate lines.  As a physiologist, I am not happy with this 
simple Monteith approach to green plants.  As a first approximation it 
works, especially in crops and in young forest plantations.  However, I 
can get just as good a relationship between productivity and 
transpiration as one can get between APAR (or IPAR) and productivity. Tom
