Effect of Salinity and Drought by Using NaCl 99.99 % and PEG 6000 on Some Growth Factors on Anabasis aphylla

Abstract. Salinity and drought affect the plants in a similar way. Salinity delays the onset, reduces the rate and increases the dispersion of germination events, resulting in reduced plant growth and final crop yield. Drought, like salinity, plays an important role not only in determining germination rates, but also influences seedling development. The present investigation has been performed to evaluate Anabasis aphylla tolerance to osmotic stress induced by polyethylene glycol (PEG) and NaCl during germination and the early seedling stages of plant development. Results indicate that only there is a significant affect for interaction of drought and salinity on root and shoot size and germination in different level. It means surly these factors have direct influence on this important indicator
