Abstract
Genotypes of two morphologically different populations of white clover (Trifolium repens L.) were reciprocally and self-grafted. Ungrafted stolon tips were also grown as controls. Grafting per se had no significant effect on shoot size, root size, leaflet width or shoot and root % P. The scion genotype had a significant effect on shoot and root size, and leaflet width. Neither scion nor rootstock genotype had a significant effect on either shoot or root % P. However, there was a significant scion × rootstock × P level interaction for shoot % P. This along with other evidence suggests that conflicting results regarding effects of scion and rootstock on % P content of plants within species is probaby due to the interaction of scion and rootstock with environment.
