Result In 5 kinds of chemical treatments, treating Z. macrostachya seeds with 20 % NaOH solution for 20 min and then cleaning the seeds with clear water got the best effect of breaking seed dormancy. By this treatment, the seed germination potential reached 83.5% in 10 d, being 58.2 % higher than CK; reached 85 % in 15 d, being 55 % higher than CK, which was near to the potential germination rate of Z. macrostachya seeds. Compared with CK, the germination duration was obviously shortened.
