Problems solved by technology

[0003] At present, due to the difficulty in obtaining the seeds of the large-flowered yellow peony, the general propagation method takes more than 2 years to emerge, and the emergence rate is very low. Most of the seeds lose their vitality during the long-term sowing and storage process, and the seed loss is serious.
There is still no rapid and high-quality germination method for the release of dormancy and seedling cultivation of yellow peony

Abstract

The invention discloses a method for promoting germination of seeds of Paeonia ludlowii. The method for promoting germination of seeds of Paeonia ludlowii provided in the invention includes the following steps: the seeds of Paeonia ludlowii are laminated under the condition of 15 DEG C, after the length of the radicel thereof is longer than 6cm, the seeds are laminated under the condition of 5 DEG C for 60-80 days, then the germinated seeds are obtained. The method overcomes the defects that the germination time is long, the germination rate is low and the emergence of seedlings is irregular.The method of the invention can allow the emergency rate to rise to more than 70% and the germination time to be shortened by one year. The method has the advantages of fast propagation rate, short cycle and high emergency rate.

Description

technical field [0001] The invention relates to a method for promoting the germination of peony grandiflorum seeds. Background technique [0002] Paeonia ludlowii (Paeonia ludlowii) is a bushy shrub of the Ranunculaceae (Ranunculacea) Paeonia genus endemic to Tibet.
