Abstract

A laboratory experiment was conducted to evaluate the cultivated wheat genotypes for tolerance to salinity by giving NaCl stress with concentration 50mM, 100mM, 150mM, 200mM, 250mM. During experiment observation were recorded for various biochemical and physiological parameters of the wheat varieties. According to increasing salt stress percent germination and seedling weight were decreased (except Lok-1 at 150 mM). Overall, with increased concentration of salinity stress reduction in germination percentage, shoot and root length, seedling weight were observed. Proline content was decreased during stress condition induces by NaCl. The highest proline concentration 5.10 µg/ml (50mM) and lowest 2.5 µg/ml (100mM) in Lok 1 and Ajeet 106 were recorded.

Conclusion

The results of study showed that there was considerable difference between most differential factor is the enzyme activity, carbohydrate, proline, chlorophyll content and physiological damage. This experiment indicates the difference between varieties is adequately depend on the salt stress condition. Based upon the observed physiological and biochemical data for the wheat varieties salinity tolerance was found in the order Lok 1 > GW 496 >Ajeet 106 >Ajeet 102 >Kedar. A significant correlation was seen among the studied parameters with increasing salinity levels. The main aim of this study is in plant breeding strategies for developing new genotypes with increased yield upon salt stress. Plant breeder may focus on selecting plants with high antioxidant activity, except plants able to accumulate more salt.
