Hi!

I would like to know:

The site/s of production of:
Gibberellins
Abscisic Acid
Ethylene

The way the following hormones are transported (xylem or phloem):
Cytokinins
Gibberellins
Abscisic Acid
Ethylene

Thank-you

CKs - transported by both phloem and xylem (though different species)

AA - production at old, senescing parts?

ethylene - produced before maturation?
transported by air
