Effect of different treatments on seed germination characteristics of two Meconopsis species
The effects of different GA3 Concentration,GA3 soaking time,temperature and light treatment on the seed germination of Meconopsis integrifolia and Meconopsis racemosa were compared,and the most favorable method for the seed germination of these two kinds of Artemisia annua was found.The results showed that:(1)100 mg/L GA3 treatment could promote the seed germination of Meconopsis integrifolia seeds.Artemisia racemosa treated with 300mg/L GA3 was the best,followed by 200mg/L GA3.(2)12h treatment and 18h treatment were the best two treatments for seed germination of Meconopsis racemosa with different GA3 treatment time.The seeds of Meconopsis integrifolia GA3 were better than the control.(3)25 ℃ treatment and 25 ℃/15 ℃ treatment could promote the germination of Meconopsis integrifolia seeds,and 25 ℃ treatment could promote the germination of Meconopsis racemosa seeds.(4)12h light/12h dark alternation treatment could promote the germination of Meconopsis integrifolia seeds and Meconopsis racemosa seeds.
