Monitoring Nutrient Uptake of Chard (Beta vulgaris var. cicla L.) Exposed to Exogenously Applied Nitric Oxide under Drought Stress

Atilla DURSUN

Nutrient uptake of chard under well-watered and drought conditions with different NO applications were investigated in this research. NO solutions were prepared with four doses (0, 50, 100, 150 and 200 µM) of sodium nitroprusside as a nitric oxide source and exogenously applied on only seeds (s) or together with seed and foliar (sf) of chard under different levels of drought according to 100% (control), 67% and 33% of the water required to reach field capacity. Nutrient uptake drastically decreased under drought stress. However, progressive effects of NO applications on nutrient uptake have be ...Более
