Ideotypes with/without crown clo

[Don.Dickmann]

My inclination is that canopy geometry traits are relatively nonplastic, e.g.
a genotype with a narrow crown will show this trait whether planted in
isolation or tightly packed in a plantation.  That is not to say that traits
will not be modified somewhat due to competition, but the relative standing of
a given genotype in relation to other genotypes will remain about the same,
regardless of how it is crowded, i.e. there will be little genotype x
environment interaction for canopy geometry traits.  That would be my
hypothesis, anyway, but it certainly needs to be more thoroughly tested.
