Abstract
Survival, leaf burn, and mineral uptake of two Asian Pyrus rootstocks were evaluated under NaCl irrigation. Potted seedlings of 2-year-old pear rootst ocks, Pyrus betulifolia Bunge (BET) and P. pyrifolia (Burm f.) Nakai (PYR) were irrigated with 0, 25, 50, 100, 150 or 200 (BET only) mM NaCl solution. BET showed high survival rate and slight leaf injury even under 100 mM NaC l irrigation. PYR however exhibited severe leaf injury and most of the test ed plants died under 25 mM NaCl irrigation. Leaf Na concentration in BET su bjected to 100 mM was similar to that of PYR at 25 mM. (C) 2000 Elsevier Sc ience B.V. All rights reserved.
