针眼大的小球，google了一下发现这个讨论，很不错
Q --- Just purchased a Haas Avocado plant from Wal-mart and planted it
on the ground. How long will it start producing fruits? Is it self-
pollinating? Thanks."
A --- Cultivars of avocados have two different kinds of flowers, usually
called simply "A flowers" and "B flowers". Some cultivars have only "A
flowers" and some have only "B flowers".
"A flowers" are receptive to pollen in the morning and shed pollen the
following afternoon while...
"B flowers" are receptive to pollen in the afternoon, and shed pollen
the following morning.
Consequently from a technical standpoint, production is best with cross-
pollination between two cultivars, one with type A flowers and one with
type B flowers.
But the reality is, most cultivars of avocado seem to get better and
better at producing furits as they get older, another pollinator or not.
And if you live in a good avocado growing climate, there's almost
invariably another avocado tree in the neighborhood that will be your
avocado tree's buddy in the next many years.
By the way, 'Hass' has A flowers. And most trees in 5-gallon cans or
larger will prodcue a few fruit the following year.
Q --- Thanks Joe. I don't know of any avocado trees in this
neighborhood. What are type B flowers? Would a Fuente avocado be a B
type?
A --- B flowers:
'Bacon'
'Fuerte'
'Jim'
'Zutano'
Others with A flowers:
'Mexicola'
'Pinkerton'
