ABSTRACT
A field-experiment was setup with earthen pots in complete randomized block design having ten replicate plants for each salt (NaCl) treatment. Initially the plants were raised by irrigating with tap water and then after their establishment, with NaCl (50, 100 and 200 mM) containing water. Various growth and biochemical characteristics were found to be adversely affected by saline treatments i.e., root length, shoot length, fresh weight, dry weight, amount of protein and antioxidant enzymes. The higher levels of NaCl (100-200 mM) in this investigation drastically suppressed the growth of plants of Suaeda fruticosa L. in the form of stunted growth. The overall increase in antioxidant enzyme activities during this study seems to be their scavenging role by neutralizing the reactive oxygen species produced during salt stress episode. It is therefore, suggested from the results of this research work that biochemical characteristics were related to a transferring of plants from being salt sensitive to relatively more tolerant. Apparently lot of work on this salt bush regarding biochemical and physiological characteristics still remains elusive and needs further experimentation under greenhouse as well as field conditions to draw meaningful conclusions.
