Abstract
In germination promoting,some Robinia pseudoacacia seeds have hardness phenomenon,the hardness seeds had a big effect on germination rate of sowing and seedling.In this experiment,the seeds were soaked in hot water under temperatures of 100,90,80 and 70℃ and simultaneously soaked by concentrated sulfuric acid respectively with 5,10,15,20 and 30 minutes,observed under SEM,to explore the best method to break the seed hardness.The results show that the seed coat had a significant inhibition on the water imbibition of R.pseudoacacia seeds,and the best method was obtained in the trial when the concentrated sulfuric acid was used for 30 minutes and the seeds soaked in hot water under 80℃.At this time,the germination percentage recorded were 96.3% and 84.0% under 25℃ respectively.
