Albinism in Poncirus trifoliata seedlings.

| Or is it Albinoism? Anyway, I collected seed from a local Poncirus last fall and stratified the seed. In all, 34 germinated. Of that 4 sprouted and were (or are)albino. Since that time two of the "albino" seedlings have developed some chlorophyll in the form of spots or streaks in the stem and leaves.
I find it very odd that such a large percentage of seedlings would be albino, at least in the first 3-5 months of life, then develop chorophyll. Could this be planting media related? genetic? or what?
It's quite interesting to watch these seedlings develop, I'm almost hoping the two that have developed the speckled foliage remain that way as they are quite striking.
I'd appreciate any thoughts on this phenomenon. |

| There is a strong link (in citrus) with the seed coat and chlorophyll formation. Wish I could remember more of this, but albinism is a more common than usual result of aberrations or injury to seed coat. |

| Could be related to the seed. I remember hearing avout acient wheat found in egyptian tombs that sprouted but was deformed and albino. Are the seedlings still alive, give us an update. If they live, selfpolonate them ad plant the seeds, this would help confirm wether or not it's genetic. |

| Of the 4 seedlings that showed the albinism, two were very sickly and died not long after the initial posting to the forum. The other two developed streaks of green and eventually became totally green and grew as well and as quickly as those that had sprouted normally. All have been planted out in the gardens, unfortunately, the flat that had all the seedlings was dumped (excited greyhound)and the tags that identified the albino seedlings was separated from the plants. Apparently either the albino seedlings die, or for whatever reason develop chorophyl and begin to grow normally. |

| That makes perfect sense. But plants dont always follow common sense... |

| Most (about 90%) on poncirus seedlings are really apomictic rather than derived from fertilization. I have never seen this result, but have noticed quite a bit of variation in seedlings from a 'Flying Dragon'(a dwarfed clone) poncirus fruit. Of 24 seedling from 1 fruit I obtained 1 very dwarf plant, 3 semi-dwarf plants, and 20 normal sized plants. I sssumed from this result that the dwarfism is really a chimerial effect, and the apomictic seedlings arose from cells of differing genetic makeup. This is just an assumption, not backed up by any other evidence. Perhaps such could be the case in your albinos as well. Geoge |
