Detection of Root Physiological Parameters and Potassium and Calcium Currents in the Rhizoplane of the Apple Rootstock Superior Line 12-2 With Improved Apple Replant Disease Resistance.

ABSTRACT: The cultivation of resistant rootstocks is one of the more effective ways to mitigate apple replant disease (ARD). We performed an ion current test, a pot experiment, and a pathogen infection test on the apple rootstocks 12-2 (self-named), T337, and M26. The ion current test showed that exposure to ARD soil extract for 30 min had a significant effect on K⁺ ion currents at the meristem, elongation, and mature zones of the M26 rhizoplane and on Ca²⁺ currents in the meristem and elongation zones. ARD also had a significant effect on Ca²⁺ currents in the meristem, elongation, and mature zones of the T337 rhizoplane. Exposure to ARD soil extract for 5 min had a significant effect on K⁺ currents in the meristem, elongation, and mature zones of 12-2 and
