Abstract:
Using two lisianthus selling varieties,‘Ceremony Orange’ and ‘Rosita I Pink Picotee’，the effects of seedling seed vernalization time（seeds of 10 ℃ low-temperature vernalization treatment 35 days，28 days，21 days，14 days，0 day） and cultivation period of GA treatment on breaking rosette were studied.The production technology on breaking rosette of Lisianthus was explored.The results showed that the two cultivars with low-temperature vernalization treatment of 28 days could improve the seed germination rate.After 60 days observation results of low-temperature vernalization treatment of 35 days ‘Ceremony Orange’ breaking rate was the highest，up to 72.9%;low-temperature vernalization treatment of 28 days ‘Rosita I Pink Picotee’ breaking rate was the highest，up to 89.6%.In the cultivation period，rosette seedlings of ‘Ceremony Orange’ without low-temperature vernalization treatment were treated GA(concentration,0 mg?L-1，50 mg?L-1，100 mg?L-1，150 mg?L-1),100 mg?L-1 GA treatment had obvious effect on promoting lisianthus internode elongation，bolting rate was 70.5% that could effectively break the rosette.Two kinds of methods were compared to solve the rosette，low-temperature vernalization treatment was the first solution of breaking rosette to lisianthus in factor，the time of flower harvest was more than 2 months earlier than GA treatment in the cultivation period.GA treatment in cultivation period could be used as auxiliary measures of seed low-temperature vernalization without breaking rosette.
