The present investigation was carried out to evaluate the
five tomato genotypes under salt stress using osmopriming
with Poly ethylene glycol (PEG 6000) as priming media on
plant height and dry matter of five tomato genotypes viz.,
Kashi Amrit , Kashi Anupam, Kashi Hemant, Kashi Sarad,
and Kashi Vishesh. Seeds were primed with four levels of
PEG 6000 viz. -0.5, -1.0, -1.5 and -2.0 MPa, along with one
hydropriming for 48 hours at 25°C. Dry tomato seeds
considered as a control (non-primed). Treated seeds of all
varieties were grown in pots with soils of different salt
concentration i.e., on 4, 8 and 12 dSm-1 along with control.
Among genotypes Kashi Hemant primed with -5.0 Mpa
was identified as salt tolerance among five tomato
genotypes as it showed maximum plant height (55, 46 and
43 cm) and dry matter (8.0, 6.5 and 6.0 g) under both control
and salt stress conditions of 4, 8, 12 dSm-1. Results of
variance analysis made clear that different osmotic
potential and priming duration had significant effect on
plant height and dry matter. The results revealed that
Kashi Hemant performed better than other genotypes at
high salt concentration and has immense potential for
cultivation in the salinity areas. It was also observed that
generally primed seeds exhibited better stress tolerance
than non-primed seeds.
