Ionic composition and metabolic changes in salt stressed roots

Soil Chemical Factors Limiting Plant Root Growth

“…Amendments of leaf litter and manure reportedly improve seed germination, plant germination, and plant growth, mainly by inhibiting excess flow of Na into plant cells through the ion holding medium (Shokohiford et aI., 1989). Stassart (1987) reported that the addition of K to a medium of low salt roots (100 mM NaCI with or without to 10 mM CaCh) decreased primary accumulation of Na and did not affect Na accumulation but reduced Na mobility. Potassium plus Ca reduced Na accumulation in high salt roots, but K increased Na flux in the xylem.…”
