Nitrogen content in shoot (S) and root (R) tissues of FL478 and IR29 rice cultivars grown without (control) and with 50 mM NaCl

Cultivar		Percentage nitrogen content
		Control	50 mM NaCl
FL478	S	4.39±0.16	4.18±0.26
	R	2.46±0.25	2.27±0.33
IR29	S	4.30±0.12	3.63±0.35
	R	2.61±0.13	2.16±0.24

At 15 DAS, plants were exposed to salt by adding NaCl to the hydroponic medium to a concentration of 50 mM. After 12 d of exposure to salt, percentage N on a dry weight basis in shoot (S) and root (R) of the tolerant FL478 and sensitive IR29 was determined. Results are mean values of three replicates (±SD) comprising three plants per replicate.
