Hi, Edwin, can you expein what do you mean more precise? Do you mean resistance to stress? Or you mean resistance to adaptation? Explants which have a root will be more resiatnt because they have increase ability to take nutrients and have better hormonal balance.
Dear Dr. In avocado plants, when double grafting is used (http://www.avocadonursery.com/gallery.html 4/11), the rootstock is grafted in an seedling that is not Phytophthora resistant, comercial
variety is grafted onto rootstock, and finally, rootstock is rooted by air-layering. In this case, could seedling affect rootstock resistance?
It would depend to the genotype of plants and pathogen you test. I guess you will find some differences anyway, but it can be unstable or insignificant.
