Yes it does. The notes from my test:
Seeds collected August 2007. Removed from pods within two or three days. Experiment started on 5th August to test varying strengths of H2O2 soak at room temperature.
By 23rd August:
100% H2O2 soak.... = 13 germ 12 not germ
1:3.... 19 germ 6 not germ
1:5.... 13 germ 12 not germ
1:7.... 10 germ 15 not germ
1:9.... 10 germ 15 not germ
1:11..... 10 germ 15 not germ
1:13 .... 9 germ 16 not germ
1:15 .... 11 germ 14 not germ*
Plain water.... 2 germ 23 not germ*
Damp vermiculite
at room temp .... 1 germ 24 not germ*
Solutions for all changed for first time on 23rd August when counted.
Sept 3rd (4 weeks from start)
100% H2O2 soak.... = 22 germ 3 not germ
1:3 .... 25 germ 0 not germ
1:5 .... 25 germ 0 not germ
1:7 .... 20 germ 5 not germ
1:9 .... 22 germ 3 not germ
1:11 .... 23 germ 2 not germ
1:13 .... 20 germ 5 not germ
1:15.... 18 germ 7 not germ
Plain water.... 4 germ 21 not germ
Damp vermiculite .... 7 germ 18 not germ
at room temp
Weaker H2O2, water and vermiculite seedlings fewer but more advanced. H2O2 seems to enhance germination but inhibit growth.
