etylene gas and fruit

moo409 - 16-1-2004 at 20:37

does anyone know any good online resources for learning about the chemistry behind plant growth/hormones/etc? This is something that has always interested me though i never have looked into it much, so if anyone here knows any good PDF text books or other online resources it would be helpful, thanks.

You could try google "ethylene" or "ethene" (Granted that google quite often lets you know how to spell thigs too)

Nice site!
Not only does it give the ethylene sensitivity of many many fruits, but also the biochemical pathway (roughly).
I remember from undergrad lectures that ethylene is rare as a hormone being in the gaseous state!
The only other one i know is nitric oxide, NO, which we all have in our bodies (nice, huh? Nature couldnt have chosen a more toxic molecule...), and which involves many signalling pathways... including having physiological effects (beyond the cellular level) , i.e. vascular, inflammation etc...

The Oracle at Delphi would smile, take a few deep breaths, smile some more, and then proslytise.

Technology for the people,

Prophesying not proselytizing. ;)

That is correct, but...;)

proph·e·sy /ˈprɒfəˌsaɪ/ Pronunciation Key - Show Spelled Pronunciation[prof-uh-sahy] Pronunciation Key - Show IPA Pronunciation verb, -sied, -sy·ing.
–verb (used with object) 1. to foretell or predict.
2. to indicate beforehand.
3. to declare or foretell by or as if by divine inspiration.
4. to utter in prophecy or as a prophet.
–verb (used without object) 5. to make predictions.
6. to make inspired declarations of what is to come.
7. to speak as a mediator between God and humankind or in God's stead.
8. Archaic. to teach religious subjects.

Which is how the oracle afforded ramen (it--we think she--was a prophet, after all), but,

I was thinking more of an overall shift in thinking on part of the listener, in which case, the original word would be sound...

Perhapse "prophsylytizing" would be a useful entity (hey, two "y's" in one word. Ha!

Very much appreciated;),

Do you think that through folly and context that anyone has learned anything?
