The
irradiated callus cultures on salt selection media showed
a decline in callus growth with increase in salt
concentration. Also the survival response in all gamma
irradiated cultures exhibited a decreasing trend with increasing
salt concentration. These findings were consistent
with the earlier reports (Ehsanpour and Fatahian
2003) wherein; the effect of salt stress in Medicago
sativa callus cultures was seen up to 120 mM NaCl
with a decline in callus growth.
