Hello,
Has anyone seen vein chlorosis in paw paw seedlings? I started
several paw paw seeds this spring, and one of them has very obvious
yellowing of the veins in the older leaves:

There are also some little brown spots along the yellowing veins:

This seedling was grown from a seed of a Susquehanna paw paw.
Chlorotic leaves with green veins seems to be a common pattern, but I
can't find any info on the web about this pattern of chlorosis being
associated with a nutrient deficiency. I've found examples this
symptom associated with a viral infection in other plants, but it
seems unlikely that a first year seedling growing inside my house
would have a viral infection.
I'm guessing its some sort of genetic bad luck, but was wondering if
anyone else has seen this kind of thing.
Alex
