ABSTRACT
Salinization has severe affects on agriculture worldwide. For successful survival and better yield, ability of seeds germinations under high salt concentration is very vital. With this object we observed the effects of various levels of NaCl (0, 25, 50 and 75 mM) on six varieties (Green leaf, Rama posa, Arka anamika, Super green, Okra kashish and Nerali) of Okra. The results clearly indicated that seeds of all varieties can tolerate the lower concentration of salt (25 mM) and higher (50 mM) greatly reduced the seeds germination while at highest concentration (75 mM) no germination was recorded. Salt treatments also reduced the dry and fresh weight of roots and shoots in all varieties considerably (P<0.05). Over all Nerali performed better and thus concluded as tolerant variety while Rama posa was proved to be a sensitive variety.
