Effect of Na₂SiO₃ and NaCl on dry weight of soybean seedlings under K deficiency

Treatment	Root d. wt (mg plant⁻¹)	Stem d. wt (mg plant⁻¹)	Leaf d. wt (mg plant⁻¹)	Root/shoot ratio
CK	1·701 ± 0·071^b	0·729 ± 0·062^b	0·781 ± 0·011^a	0·284 ± 0·024^b
−K	1·120 ± 0·090^c	0·546 ± 0·023^d	0·489 ± 0·014^c	0·195 ± 0·020^d
−K + Na₂SiO₃	2·460 ± 0·068^a	0·894 ± 0·011^a	0·717 ± 0·016^a	0·318 ± 0·010^a
−K + NaCl	1·723 ± 0·072^b	0·629 ± 0·013^c	0·633 ± 0·040^b	0·245 ± 0·019^c

Data are the mean ± s.e. of four replicates with each replicate containing at least three seedlings. Soybean seedlings were grown in medium watered with full nutrient solution (5 mm K) (CK) and K-deficient solution (1 mm) (−K) in the absence and presence of 2 mm Na₂SiO₃ (−K + Na₂SiO₃) and 4 mm NaCl (−K + Na₂SiO₃) for 60 d. Values with different letters within each column are significantly different at P < 0·05.
