“Uneven ripening” in Pawpaw (Asimina triloba)

General Fruit Growing

Hoping to start a serious, specific thread to discuss and determine cause and cure for “uneven ripening” in pawpaw.

What is uneven ripening?
For the purposes of this thread, it is the appearance of white flesh amid otherwise normal ripe flesh.
This could take a range of forms: from large sections of firm/hard white tissue to “swirls” of white intermixed.
A concomitant sign is soft, aromatic bulges n whole fruit with remaining areas being hard and odorless.

Perhaps this is an easy one in terms of cause and cure, but I’ve never seen this adequately explained.

What is the cause?
What is the cure?

Ive heard atwood specifically is very prone to this, can others confirm?

That was my experience as well as others.

However, I want to focus on the specific “science” in this thread if possible :victory_hand:

Would bruising of green fruit be a cause? Would poor pollination affect them, like if they cut open the unevenly ripened fruits does anyone find underdeveloped seeds?

Yes Atwood had big problems here a few years ago but not recently, so intermittent, skips years here.
