Abstract
The effects of different methods(treatments of acid,alkali,plant hormones,high temperature,ultrasonic wave and scraping seed coat)for breaking the seeds dormancy of 4wild grass species(Cyperus rotundus,Digitaria sanguinalis,Echinochloa crusgalli and Vicia)were studied.The results showed that all the treatments had no significant effect on the seed germination of D.sanguinalis(P0.05).The seed germination of Vicia was significantly improved from 1.11%to 96.67%(P0.01)by scraping seed coat,and no significant effect was observed for other treatments(P0.05).By soaking seeds in 20% NaOH solution for 30 min,the seed germination of C.rotundus and E.crusgalli were significantly increased from 10% and 2.22%to 86.67%and 58.33%respectively(P0.01).In addition,the seed germination of C.rotundus was also significantly increased by the treatment of 1 000mg/L of GA3(P0.01).And other treatments had no significant effect on the seed germination rate of C.rotundus or E.crusgalli(P0.05).These results indicated that different species of wild plant seeds had different dormancy characteristics.D.sanguinalis seeds had no dormancy.The seed coat of Vicia should be scraped to improve the germination.20% of NaOH and 1 000mg/L of GA3 could break the seed dormancy of C.rotundus.20% of NaOH could break the seed dormancy of E.crusgalli.
