Welcome, Guest. Please login or register. Author Topic: Variegated Poncirus Read times. Florian Sr. Member Posts: Solothurn, Switzerland. I was browsing citrus pages when I saw this picture of a variegated Poncirus. Is there any information available? Is there anyone growing variegated Poncirus? Florian This link gives you the answer. Unfortunately in French. The origin of this is genetic but most often the influence of a fungus Aspergillus flavus and Alternaria tenuis present on the seed coat.
No, I believe this is a genuine chimeric plant. Best regards, Ilya. So from what Origin the chimeric factor? The mutation does not so much be induced by fungi? Quote from: shiro on March 06, , PM. The plant remains of the Poncirus trifoliata. But it has mutated became a chimeric plant by the contaminating effect of the fungus. Finally this is the answer I can give you. After I remain open to other possibilities of chimeric induction grafting, etc.
If ILYA11 has documentation or other that can tell us more about this type chimera it would be very interesting because it is pretty beautiful a variegated poncirus. Because in general it does not live long, so if there is a way to get some durable it would be interesting.
Yes, it is well known fact that variegated citrus seedlings are due to the fungal infection of one of the three embryonic layers. Fungus is interfering with chlorophyll synthesis,but this is not a mutation.
It is not resulting in periclinal stable chimera, since fungus is either cured or spreads to other layers. True chimera due to the gene mutation are extremely rare, usually they arise as variegated branches in adult plants. In Japan they selected Snow Dragon poncirus that is true pereclinal chimera. From 60 seedling that came out in December, one of them looks exactly the same. Variegated, I am not sure if this is a mutation or is from a fungus.
