Harold:
I was too quick in hitting the Send button. I should have taken
the time to discover
Zielinski included also, classification of buds, on page 79. It
evidently does not recognize
shoot initials in apple and pear as components of their buds:
Classification of Buds
1. Wood or leaf buds, which develop into leafy shoots.
2. Fruit buds, which are of 2 kinds:
a. Simple buds, which develop into one flower (peach, apricot,
almond) or several flowers (cherry, plum).
b. Mixed buds, which develop into a cluster of leaves and flowers
together (apple, pear).

The discussion about TRV has been most interesting, but I have
another question about bud terminology.
Within the Rose family, we have crops that have differing types of
flower-containing buds:
- a single flower, no shoots -- Apricot, peach, and nectarine
(plus some individual buds on plum)
- multiple flowers, no shoots -- sweet tart cherry (+ other
cherries), plums (most buds)
- multiple flowers + shoot initial -- apples pears
The first category, I believe, is termed a simple bud.
The third category, I believe, is a type of compound bud termed a
mixed bud
But what is the plant anatomical / horticultural term for the
second category? I had viewed it as a compound bud because of the
multiple flower initials, but the typical example used for a
compound bud is grape (Vitaceae) which has a primary, secondary,
and tertiary bud all enclosed within the bud scales at each node.
I have NOT been able to find any source of reference with a term
for the cherry and plum type of complex bud.
Any ideas / references out there??? I have been putting together
an Extension document on evaluating cold injury damage to fruit
buds and the evaluation process differs between the bud types. So
use of some terms would be helpful in shortening it. The intent is
to have it both in printed form and as a PDF document on the web.
So I'd really like to have the terminology to be correct!
Thanks much!
