Table 1.

Biomass, ¹⁵N AT% and Ndff% in the roots of T. distichum under three N treatments.

Treatments	Root Biomass/g	¹⁵N AT%	Ndff%
CK	0.30 ± 0.01 ^bc	0.37 ± 0.00 ^c	/
1 mM ¹⁵NH₄⁺	0.34 ± 0.02 ^ab	0.63 ± 0.03 ^a	2.65 ± 0.31 ^a
1 mM ¹⁵NO₃⁻	0.26 ± 0.01 ^c	0.48 ± 0.04 ^b	1.16 ± 0.38 ^b

Different letters behind the values in the same column indicate significant differences among the treatments according to Duncan’s Multiple Range Test at 5% level. ¹⁵N AT%: ¹⁵N Atom; Ndff%:¹⁵N from N source.
