Abstract:
Taking Primulina gueilinensis as materials，using different concentration treatments of GA3 (50 mg/L,100 mg/L,500 mg/L,800 mg/L) for the whole plant spraying processing,observed its florescence and flower morphology index measurement.The results showed that GA3 could blossom and extend the flowering period of Primulina gueilinensis.GA3 played a role in promoting height of pedicel and leafage,length of corolla and number of flowers and had little effect on pedicels height/leafage height，corolla width，number of inflorescence.When the concentration of GA3 was 500 mg/L,it had better effects on flower period advanced 9 days and extending the florescence 25 days,as well as pedicel height，leafage height，corolla length and flowers number were 17.81 cm，13.71 cm,5.61 cm,74.8 flowers respectively.
