Abstract
Salinity is one of the severe abiotic stresses among the
different stresses of tomato crop. An experiment was conducted
to find out the effect of osmoprotectants on tomato under NaCl
salinity stress to study the changes in physiological and
biochemical parameters due to saline stress. Five varieties of
tomato crop procured from Main Vegetable Research Station,
Anand Agricultural University, Anand were: QT-2, AT-3, ATL-
01/19, ATL-97/44, AND-1. These varieties were differing in their
degree of salt tolerance. The seeds treated with four different
osmoprotectants, proline, trehalose, sorbitol and putrescine
were firstly grown in petri plates at four different concentrations
of NaCl i.e. 50 mM, 100 mM, 150mM and 200 mM and used for
various physiological analysis like germination percentage,
seedling growth, moisture and based on the results
