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

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?
