Quinoa is a crop with high nutritional value, which its cultivation as a source of food is increasing in different regions of the world. In the present investigation, the effect of salt stress in combination with different treatments of hydrogen peroxide, sodium nitroprusside and calcium carbonate was studied on growth and physiology of quinoa at seed germination stage.Salt stress significantly decreased the plant length and carbohydrates, while hydrogen peroxide, sodium nitroprusside and calcium carbonate treatments significantly reduced the negative effect of salt stress on quinoa.Salt stress significantly increased the non-photosynthetic pigments of phenols, flavonoids and anthocyanins to reduce the accumulation of reactive oxygen species. The hydrogen peroxide, sodium nitroprusside and calcium carbonate treatments significantly increased phenols, flavonoids and anthocyanins to a higher level than salt stress to increase quinoa antioxidant property. Accordingly, the hydrogen peroxide, sodium nitroprusside and calcium carbonate treatments effectively reduced the negative effect of salt stress on quinoa crop.
