Abstract:
Taking the seeds of Meconopsis baileyi，Meconopsis baileyi ‘Hensol Violet’ and Meconopsis baileyi ‘Alba’ as experimental materials，the experimental methods include vernier caliper measurement，electronic balance weighing，different temperature treatment and gibberellin(GA3) treatment.The research contents include the length and width of seeds，1 000 grain weight，water absorption rate，germination rate，the effects of 25 ℃/15 ℃ and 20 ℃/10 ℃ temperature treatments and different concentrations of GA3 on seed germination，in order to compare the phenotypic and germination differences of Meconopsis baileyi and its two varieties，and to find ways to promote their germination.The results showed that the average length of Meconopsis baileyi，Meconopsis baileyi ‘Hensol Violet’ and Meconopsis baileyi ‘Alba’ seeds was （1.149 1±0.127 8）mm，（1.173 5±0.124 1）mm，（1.292 1±0.146 4）mm，the average width was （0.652 6±0.079 4）mm，（0.702 8±0.073 4）mm，（0.753 3±0.086 8）mm，and the 1 000 grain weight was （0.289 7±0.012 7）g，（0.320 5±0.005 5）g，and （0.370 7±0.014 6）g，respectively.The germination effect of seeds at 20 ℃/10 ℃ was better than that at 25 ℃/15 ℃，Meconopsis baileyi>Meconopsis baileyi ‘Hensol Violet’>Meconopsis baileyi ‘Alba’ at the same temperature.GA3 with concentration of 400 mg?L-1 was the most favorable for Meconopsis baileyi seed germination.Under this condition，the germination rate reached 74.44%，which was 20% higher than CK.
