There is quite possible that self-ingintion
is used by particular plant groups purposefully,
as a step of [ darwinian ? ] evolution.
You can perhaps take some amalogy in mass-suicides
of dolphines jumpimg on the shores. I believe,
the reason for this in not well understood.
(however, exploratory hypothese like Mutch's are
unlikely to be welcomed by funding agenicies
whose pupose is suffocate science, not advance it).
These are my 2 cents. Alex Berezin
