effect of water (drought) stress on water relations of haloxylon aphyllum and h. persicum*
root and shoot osmotic and elastic properties of two species of haloxylon aphyllum and h.persicum in response to water stress were studied. the main goal of the study was to determine if the tissuesof two species utilize osmotic adjustment and/or enhance their elastic property during prolonged water stresscondition. the results showed that although tissue elasticity of both species of haloxylon...
متن کاملStrategies for adaptation of Suaeda physophora, Haloxylon ammodendron and Haloxylon persicum to a saline environment during seed-germination stage.
BACKGROUND AND AIMS Germination is very important for plant establishment in arid regions. The strategies taken by halophytes during the seed germination stage to adapt to saline environments in an arid zone were investigated in Suaeda physophora (euhalophyte), Haloxylon ammodendron (xero-halophyte) and Haloxylon persicum (xerophyte). METHODS Seeds of S. physophora, H. ammodendron and H. pers...
