You may be correct - in the literal scientific sense. I don't know. Frankly, I don't know what half the words you used actually mean! (That's due to my ignorance of the proper biological terms.)
My definitions of "adventitious" vs "needle" buds are commonly used by us non-scientists to describe the different buds that JBP have.
I don't know who coined the terms "adventitious", "needle buds" or "decandling". No matter. The important thing is to convey the concept.
You didn't coin the terms, but you have been very adamant in their use around here. So let's clear it up with a simple botanical discussion. It's not that difficult, and if you're teaching, it wouldn't hurt to understand a few basic terms:
Bud names by location:
Apical: top terminal bud
Terminal: bud at the end of branch
Axillary/lateral: bud at leaf axils
Adventitious: buds anywhere else, and can include former axillary buds.
Bud names by status:
Accessory: next to the terminal buds (The "whorl" of pine buds. One terminal bud surrounded by accessory buds)
Resting: formed last year to grow this year
Latent/dormant: resting for more than a year (the rings around Japanese Maple have these)
Pseudoterminal: one which takes over when the terminal is removed
Needle buds, as you specifically use the term, are in fact axillary buds; which could be adventitious, if the needles surrounding the bud are gone. Calling them "axillary needle buds" would not be incorrect.
Adventitious buds, as you use the term, are actually resting/accessory buds, and even axillary buds. It is less likely they are actually adventitious buds, because, by definition, adventitious buds are not terminal or axillary. My understanding is that summer "decandling" activates "resting/accessory buds", and with any luck, some "axillary buds".
