Re: [Aroid-l] Re: blooming all at once

Well, it might all sound unlikely but with numrous species, of which sevearl of the bamboos ae the most familiar, this is exactly what happens. Perhaps even more bizzarly, forest trees in the Bignoniaceae and also the genus Ficus flower simulataneously over enormous tracts of forest and they are SEED raised and not identical clones.

Dear John and Friends,



I tend to see what John is saying---what Pete had suggested, that the
blooming was somehow ingrained into the genes of that one clone so that
they all bloomed at once, no matter where in the word they grew, made some
sense, but thinking about it, I could 'buy this' for the FIRST blooming,
as perhaps as Pete suggested, like in a mammal attaining puberty, and if a
mammal were cloned, ALL would attain this at the same time. BUT---what
about the second and third blooming, etc.?? Surely their inner 'clock'
would and could not signal all these plants spread all over the world and
growing under way different conditions to 'wait' 20 or so years AFTER the
initial blooming and then, ''wham', all bloom together again??

What a good thing to have this true mystery in an aroid!!

Good Growing,



Julius




to me the fact that they are of one clone doesn't address the mystery.
how does the plant know? what is the trigger, given that it can't be,
say, the 15th spring if plants are blooming at the same time in the
northern and southern hemisphere? to me, it's an extreme example of a
more common mystery. many plants continue to flower in the spring of
their country of origin even when moved to the opposite hemishere.



even when they are grown from seed and even, in many cases, when the seed
has been dormant for years. how can a seed keep track of time?



john
