| ABSTRACT Salinity is among the most common and severe abiotic stresses that drastically affects crop productivity all over the world. To evaluate the effect of salt stress on seed germination, early growth, antioxidant enzyme activity and ABA content of chicory ecotypes (Cichorium intybus), a factorial experiment was conducted at College of Agriculture, Shiraz University in 2014 based on completely randomized design with four replications. The treatments comprised five salinity levels (tap water, 3, 6, 9, 12 dS m-1) of sodium chloride on the ecotypes of Sefid Shiraz and Siyah Shiraz. The results showed that germination characteristics and primary seedling growth decreased in both ecotypes with increasing in salinity severity. The effects of salinity on... |
