Divergences in hormonal and enzymatic antioxidant responses of two Chicory ecotypes to salt stress.

To evaluate the effect of salt stress on seed germination, early growth, antioxidant enzymes 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 (tapwater, 3, 6, 9, 12 dS m(-1)) of sodium chloride on Shirazi-black and white chicory ecotypes. The results showed that germination characteristics and primary seedling growth were decreased in both ecotypes with increasing in salinity severity.
