I do not know about the compatibility of Single, Carrizo and Troyer with the Italian lemon varieties that you list, but I can tell you that Swingle, Carrizo and Troyer are incompatible with the Eureka lemon. In the case of Carrizo and Troyer, although they are incompatible with Eureka Lemon, the are compatible with Lisbon lemons. Therefore, there might or might not be an issue with various other lemon cultivars. If you find definite results to your question, please post it on this forum.
