3 years ago An example with current LAI:
With the increase of leaf size:
It works if we control the number of apices (as it is done for MCol 1684). If not it highly increase the LAI due to the total number of apices.
This is the curve for individual leaf size for branching variety:
And this is the curve for a non branching or late branching variety (with double individual leaf size):

3 years ago Considering reduction in the leaf size by branching level (in addition to the normal reduction):
This is the current leaf size:
And current LAI:
I will try a 0.8^2 multiplicative factor for each branching level just after the curve reach 900 GDD.
This is the new leaf size curve:
The effect can be too strong for early branching varieties:

3 years ago Maybe a 0.9 factor is better so for 6 branching levels the leaf size is reduced by 50% (in addition to the actual reduction due to the curve):
The new curve:
New LAI:
Testing other experiments:
*Before:
*Now:
*Before:
*Now (0.9):
*Now(0.8):
The curve for potential leaf size works ok for non-branching varieties but it underestimates the leaf size for non-branching varieties which usually reduces the leaf size just in a 50% (see below example for MCol 72-non branching variety)
