Cold temperature tolerance of G.16 and G.935 apple roots
2011
Moran, R.E. | Zhang, D. | Sun, Y.
G.16 had similar root tissue cold hardiness as M.26 EMLA. Significant root death, 40%, occurred at temperatures of -12°C in both rootstocks. Tree growth of M.26 EMLA after 40 days in a greenhouse was reduced by exposure to -10°C and colder, whereas tree growth of G.16 was reduced by -12°C. In a separate experiment, G.935 had greater cold hardiness than M.26 EMLA, based on shoot growth following exposure to freezing temperatures to a low of -16°C. Root tissue relative electrical conductivity (REC) increased linearly with decreasing temperature in both G.935 and M.26 EMLA, but the rate of increase in REC was greater in M.26 EMLA.
