Using Meconopsis integrifolia seeds as materials,the effects of different temperature condi-tions and exogenous hormones on seed germination of Meconopsis integrifolia were studied.The results showed that the optimum temperature for seed germination was 20 ℃.Seed low temperature stress and its cooperative temperature change treatment,plant exogenous hormones GA3,ETH and CKT solution soaking treatment could promote the release of mandormancy of Meconopsis integrifo-lia seeds,and significantly improve seed germination rate,germination potential,average germina-tion speed and germination index.400 mg/L GA3 solution soaking treatment had the best germination effect.
