with respect to the salt-treated seedlings. Rahman et al. (2016) observed in their work
on CaCl 2 application reduction of proline content in comparison with the seedlings
treated with NaCl alone.
4.3 Carbohydrate Content
The reducing sugar accumulation was increased 31%, 1.9 times and 1.2 times in CN2,
PAT and DDH variety, respectively, in stressed set seedlings. The considerably best
decrease in reducing sugar accumulation was found in the treatment set of 15 mM
CaSO 4 (36%), 5 mM CaCO 3 (75%) and 5 mM CaCl 2 (88%) in CN2, PAT and DDH
variety, respectively, with respect to the 200 mM NaCl-treated seedlings (Fig. 3).
Similar result was found by Hakim et al. (2014) in the rice varieties of MR52 and
Pokkali.
On the contrary, starch content was decreased 16.6 times, 1.9 times and 56%
in CN2, PAT and DDH variety, respectively, in stressed set (Fig. 5). However, the
