Application of plant growth regulators on flowers plantation--roses
The effects of plant growth regulators on roses:
1.Root King promotes rooting growth
Use high-quality seedlings, the semi-lignified top branches and secondary branches as cuttings,remove some leaves properly , and use PINSOA rooting king to promote rooting.
2.Ethephon promotes growth
After the rose cuttings grow root, spray the base of the seedlings with 250 mg/L ethephon solution , and spray again once every 2 weeks to promote the growth of side branches.
3.PP333(Paclobutrazol) promotes flowering
After pruning the pot roses, when the new branches grow to 5-10cm long, irrigate the soil with 300mg/L PP333(Paclobutrazol) solution. When watering, it is appropriate to have the solution just flowing out from the bottom of the pot. It can bloom about 2 weeks earlier than the untreated ones. Because PP333(Paclobutrazol) remains in the soil for a long time, it can also prevent branches from growing excessively for a long time.
4.Gibberellin（GA3）
During the leaf-expanding stage of roses, spraying the whole plant with 100 mg/L Gibberellin（GA3) solution can make flowering about 6 days in advance, but the flowering period may be shortened.
