Anton,

 

I haven't grafted peach onto Citation but I have grafted onto St Julian A.  I gave up grafting onto St Julian A because of problems.  The peach trees are doing great on Pumiselect.  I have noticed a little problem on the two I have on Krymsk 1.  I have more budded in on Krymsk 1 that I did this summer.  Two is too small a number to make a judgement on it.  When you say standard stock are you talking about just any peach seedling or ones like Lovell?  The one thing I don't like about Pumiselect is that it has a brittle shank.  I had a couple break off well below the graft union in a strong wind last fall before the leaves had fallen.

Subject: [NAFEX] disease and dwarfed peaches

I've noticed over the years that all the peaches I have on Citation rootstock look relatively sick compared to those on standard stock.  They typically have poor color in the leaves, not dark green and show epinasty (leaf rolling) and increased bacterial spot damage.  The effect is most extreme late in the season.

At first I blamed it on the scion cultivar.  My first peach dwarfed on Citation was George IV.  I've never grown such a sickly tree before, though the peaches were good.  Now I've got more cultivars, including one with a standard comparison, Indian Blood Free.  IBF is rather susceptible to bacterial spot anyway, but the other symptoms don't show on the standard stock.

Have others seen similar effects of dwarfing rootstocks on peaches? 

My genetic dwarfs are all very healthy, so it doesn't appear to be the dwarfing per se.  However, another contributor with a good collection of peaches has reported similar effects from PumiSelect.
