PCA / PCNA / PVA / PVNA / persimmons and what this all means

This is my way of understanding this:

P = Pollen
C = Consistent
N = Non
A = Astringent

J = Japan (kaki from Japan are known to ripen on the grafted-trees)
C = Chinese (kaki from China are known to be ripened mainly with CO2 gas)

PCA = Pollen Consistent Astringent
No matter the pollen had at it, it will always need ripening off the tree.

PCNA = Pollen Consistent Non Astringent
This means that pollen does nothing. And that the fruit ripens on the tree.

Now, when pollen is introduced to plants that can change flavor. This is the letter: V = Variable

PVNA = Pollen will change the fruit flavor. It’s Non-Astringent still so the tree will ripen the fruit vs gas.
PVA - Pollen will change the fruit flavor. This time the A means it needs gas (commercial ripening - CO2 gas) to ripen since the tree alone is not capable of ripening the hanging fruits on it.

A = Astringent so it must ripened off
NA = Non-Astringent so it may be ripened on the tree (or off: kitchen/tables in basements/garages)

I must of read for an entire day and then again thru the week to understand this. (Yet) it’s so simple!

This is/These are all the things that happen with growing: hybrids or kakis or both together and each grafted cultivar has its’ own way of ripening/flavor. American persimmons simply have or don’t have seeds.

Jerry Lehman always stated via email/in-person/phone:

‘American persimmons are as fruitful/(precocious & prolific) w/o males and their flavor isn’t effected with or w/o the presence of pollen… and that a completely seedless orchard of female-only-cultivars is entirely possible without surrounding pollen.’


This is helpful, but it might be more clear to use another descriptor for astringency instead of “ripening on the tree”. Perhaps ripe when soft or something like that?

For PVA fruit, are you saying that’s it’s impossible to obtain ripe fruit without CO2? Seems odd—what happens in nature? And what did people do before industrialization? I’m just learning about persimmons and am not familiar with PVA.

Iirc, Chocolate is the most commonly grown PVA type.
