Effects of different treatments on Toxicodendron succedaneum seed germination from three provenances

In order to find out the best breeding approach for increasing germination rate and gaining more high-quality seedlings,and to provide instructions for development of germplasm resources and relevant industries of lacquer tree (Toxicodendmn vernicifluum),germination conditions for lacquer tree seeds from different provenances were researched by means of the all-factor test with three-factor and three-level,in which there were total 27 treatment groups and single variant was set in each treatment.The results showed that the best germination conditions for the seeds from A provenance were 98％ H2SO4 treating for 30 min,400 mg/L GA3 treating for 60 min and sand covering for 30 d;those for the seeds from B provenance were 98％ H2SO4 treating for 30 min,400 mg/L GA3 treating for 60 min and sand covering for 20 d;those for the seeds from C provenance 98％ H2SO4 treating for 30 rain,400 mg/L GA3 treating for 60 min and sand covering for 20 d.98％ H2SO4 treating time,400 mg/L GA3 treating time and sand covering time had extremely effects on germination rate,bud length,bud diameter of lacquer tree seeds from different provenances.
