Abstract
Scion-rootstock compatibility and the anatomical structure of the graft union was studied in the scion varieties Jacaranda and Kardinal grafted on the rootstock R. canina (dogrose). Horizontal and vertical wood samples, cut from the graft union, were stained with methylene blue, safranin and lugol (IKI). All samples were studied under trinocular microscope in addition to macroscopic studies. Jacaranda had a very good graft compatibility with R. canina, whereas Kardinal had only a medium good compatibility.
Starch accumulation was detected on R. canina in the Kardinal/R. canina graft combination.
This situation was assumed to be the main reason for a decrease in the nutrient transfer between scion and rootstock.
In each of the two graft combinations, xylem and cambium tissues were continuous in the graft union.
Shoot growth was good in both Jacaranda and Kardinal soon after grafting.
