Several chemical methods to break dormancy of Aeluropus littoralis seed

Present study investigated the effects of different soaking time with 98%H2SO4, different concentrations of NaOH and KNO3 solution on seed germination and seedling growth of Aeluropus littoralis. The results showed that both germination rate and seedling length of A. littoralis were significantly promoted by immersion in three chemical reagents. The effects were better, when putting seeds in 98%H2SO4 solution for 5 min, 10% NaOH solution for 30 min and 0.2% KNO3 solution for 24 h, with seed germination of 13.3%, 42.2% and 20.0%, and seedling length of 0.79 cm, 1.97 cm and 1.13 cm, respectively. It was concluded that the best treatment for the germination of A. littoralis was immersion in 10% NaOH solution.
