Abstract
The effects of five different N-sources (KNO3 + NH4NO3 = control, KNO3, NH4NO3, NH4H2PO4, L-alanine) on growth, nutritional status, chlorophyll (Chl) content, and photosynthetic parameters of the apple rootstock MM 106 shoots cultured in vitro were investigated. In comparison to all the other treatments, control explants grown on a MS medium containing KNO3 + NH4NO3 had the highest fresh mass, Chl content, net photosynthetic rate, transpiration rate, and stomatal conductance.
