Dr. Manners. Do you have any information regarding grafting to variegated citrus?

I was just wondering if using a variegated rootstock would improve the chances of the scion producing a variegated sport?

The variegated Lisbon lemon I have roots very easy & I was thinking of using that as a rootstock to see if I would get a better chance of the resulting scion producing a nice variegated sport.

No.. I'm not Dr. Manners.............. you already know that though..

but just as a FYI I did the same thing a few years ago, during rooting Seville cutting I had a fair number of Variegated lemon cuttings,, and some people around used rough lemon as a understock here so I thought "What the heck"

I did get Variegated lemon on its own root,, all the buds to it came true to type, (as would be expected)

OK, well in the spring I'm going to use a bunch of my rooted lisbons as rootstock & see if it induces variegation into the scion of different lemons.

For the time being, I grafted a Bearss lemon to the variegated lisbon rootstock to see if I can get some variegation in the Bearss.

I'm not very hopefull, but it is worth a try.

Just tought you might want to see something I tried once

OK... What exactly did you do? Is that variegated swingle?

You might have better luck giving your bud-sticks a dose of x-rays!
I noticed you can buy an x-ray machine on ebay

Any engineers will be amused by the specification
"Adjustable KV (revolutions per minute of engine)"

If I remember correctly (it was done many years ago, and yes I know the date on the photo is incorrect) it was not swingle. Swingle was not used a lot then I believe it was a called “sun chu sha” I got two liners that had variegated leaves and used two pieces of a variegated Valencia twig, to see if variegated grafted to variegated R/S would give a better chance of not reverting to green as most grafts do. If I remember correctly it flushed three times and one side of the tree remained variegated while the other side remained green, the tree died a year or two later when I dropped the pot and broke off most of the root mass. I think that’s why this R/S was not used too much the root mass was very small.

Sun chu sha is a mandarin & does not have trifoliate leaves.

Interesting you say your variegated stuff reverts back to green. I have never had that problem. I have had single bud revert back to green & I just cut that flush off. I have also had quite a few buds produce a albino flush which is also removed.
