The aim of this study was to determine cross-stress
tolerance in plants have different seed
nutrient content (maize, bean and wheat). For this purpose, salt
(50 and 100 mM NaCI) and cold stress (12/7oC) separately or in
combinations (cross stress) were applied and studied the
alterations of root and stem growth, total soluble protein content and
antioxidant enzyme activities (superoxide dismutase
(SOD), catalase (CAT), peroxidase (POD) and ascorbate peroxidase (APX)) associated with
induction of cold hardiness by salt stress. Salt
and cold stress and its combinations caused inhibition of root and stem growth
and antioxidant enzyme activities (SOD, CAT, POD and
APX) were significantly increased or decreased due to
both salt, cold stress and its combinations. The
soluble protein content increased in maize and wheat while decreased in bean in
all applications. Cross-stress, on the other hand, decreased the soluble
protein content according to alone salt or cold stress in all plants. As
a result, there is not determined any relationship among cross-stress
tolerance and growth, soluble protein content, antioxidant enzyme
activities or plants have different energy sources. For example; while the
highest increase in SOD, CAT, POD and APX activities were observed in maize,
root-stem growth was most decreased in maize.
