Table 1 Effects of HRW treatment on CdCl₂, NaCl and H₂O₂ concentrations in mycelia of H. marmoreus

Treatments	CdCl₂ (nmol/L)	H₂O₂ (mmol/g)	NaCl (mg/g)
H₂O → H₂O	ND^c	62.4 ± 4.328^c	0.101 ± 0.008^c
H₂O → HRW	ND^c	60.1 ± 6.301^c	0.098 ± 0.003^c
CdCl₂ → H₂O	230.78 ± 9.876^a	–	–
CdCl₂ → HRW	184.62 ± 11.752^b	–	–
NaCl → H₂O	–	–	2.307 ± 0.506^a
NaCl → HRW	–	–	1.606 ± 0.340^b
H₂O₂ → H₂O	–	132.18 ± 9.672^a	–
H₂O₂ → HRW	–	119.11 ± 11.012^b	–

8-day-old mycelia were pretreated with 0, 50 μm CdCl₂, 1.0% NaCl and 2 mM H₂O₂ for 24 h and then were treated with or without treatment with 100% HRW. The control group was treated with water. Values are mean ± SE of three independent experiments with at least three replicates for each. Different letters within columns indicate significant differences (P < 0.05) according to Duncan’s multiple range test
