Abstract:
Proso millet (Panicum miliaceum L.) is one of the commercially most important millet crop. Different concentrations (50mM, 100mM, 150mM and 200mM) of NaCl salt stress were imposed to proso millet plants in order to study the tolerance of proso millet towards salinity stress. To understand the response of proso millet plants towards the salinity stress, studies were conducted on the synthesis of proline, malondialdehyde (MDA) and total soluble sugars. Salt stress-imposed plants expressed increased level of these metabolites. In addition to this, decrease in chlorophyll content, relative water content (RWC) and chlorophyll stability index was observed under salt stress conditions. In case of water saturation deficit (WSD), it showed indirect relationship with RWC. Based on these results, the potential salinity-related candidate genes or quantitative traits may be isolated and characterized from proso millet.
