Hybrid Seedling Cotyledons
mikkel:
This winter I grow many different hybrid seedlings. I observe that Poncirus seedlings have their cotyledons not paired like in Citrus. The 2nd cotyledon is always higher than the first one. Citrus and Microcitrus have them very close to each other in pairs.
Citrus x Poncirus seedlings are mixed. Some are paired but the most are like Poncirus.
Does someone observed the same?
I wonder if this trait is suitable to find more Citrus like hybrids among seedlings. For now it is impossible to tell if it is connected to poncirin free fruits but would be interesting to find out.

I think that what you are taking for eccentrically situated cotyledons are true leaves with cotyledons that are still covered with testa in germinated seeds.

Thanks Ilya! I wonder what is wrong with my computer...
Your`re right! These aren`t cotyledons.
