This question may be restated - is there a characteristic that irises have
that correlates with a lack of seed dormancy? I have read about similar
studies with potatoes. The lack of dormancy for true or botantical potato
seed has been associated with earlier maturity for the tuber propagated
plant.
It is possible that this lack of seed dormancy in irises may correlate with
some other characteristic that may or may not impart better adaptation to
hot climates. This correlation may or may not be the same for different iris
species. Only further research could reveal if any of these relationships
exist. Perhaps someone else on iris-talk is aware of specific studies
designed to research possible relationships between seed dormancy and
other characteristics.
