Response of radiata pine to salt stress. I. Water relations, osmotic adjustment and salt uptake



Response of radiata pine to salt stress. I. Water relations, osmotic adjustment and salt uptake



Australian Journal of Plant Physiology 4(4): 637-646



Transpiration, total needle water potential and osmotic water potential, and proline concentration in needle sap were determined in radiata pine (Pinus radiata) seedlings subjected to a stepwise decrease in osmotic potential of the liquid rooting medium by addition of CaCl2 or NaCl (absorbable), or PEG 4000 (non-absorbable). Resultant concentrations of N, P, K, Mg, Ca, Na, and Cl were determined in needle, stem and root tissue as well as in expressed needle sap.
