Does not look like albino chimera, probably either some root deficiency or a viral infection.
Best regards,

I tend to agree with you, Ilya. It lacks the layered look of chimeras. Several plants display yellow new growth that improves with foliar nutritional sprays. We have experienced a wet, chilly, prolonged spring to this point and there may be problems getting nutrients to the foliage.

An example of defects: these two plants suffered bark freezing that healed and the plants recovered, but still are likely to carry the susceptibility.

That's not variegation. Ilya is correct.

Does anyone know what causes this?  It seems to be showing up on the new growth of Poncirus crosses.

I have additional plants with chlorotic growth. I haven't definitively determined the cause, hopefully it's nutritional rather than viral. In the worst cases apical growth is stunted and there is branching from a lower position on the stem.




Apical growth arrested, with unusual branching from a lower position.

It looks like just new growth.  I assume you have a nutrient plan for your trees.  The yellow should turn green as the growth matures.
