To study the effect of 25 mg/L salicylic acid(SA) on rice(Oryza sativa L.) seedling roots under NaCl(0
50
100 mmol/L)
content of proline
soluble sugar and activity ofammonium assimilation enzymes of rice root and relative parameter were detected.25 mg/L SA decreased roots proline content and increased total soluble sugar content dramatically under NaCl stresss.And plant adapted salinity when soluble sugar as main compatible osmolyte in following aspacts.Activities of the key enzymes of nitrogen assimilation
such as glutaminesynthetase(GS) and NADH dependent glutamate dehydrogenase(NADH-GDH) was induced
and soluble protein content increased
that is to say nitrogen assimilation was enhanced.
