Example Embodiment

[0018] Example 1

[0019] The material used in this example is four-year-old Luhehong (Peaonia.suffruticosa cv'Luhehong').

[0020] A method for promoting off-season peony flower bud germination and branch growth, comprising the following steps:

[0021] Upper potting: In mid-to-late October, select 4-5 year old plants suitable for flowering, and start seedlings. Soak the peony roots to sterilize and dry in the shade. The soil is carefully screened, mixed with cow dung and vermiculite, and then the peonies are planted in flower pots, watered thoroughly, and placed at natural temperature for about 20 days to promote the rooting and survival of peonies.

[0022] Low temperature treatment: When the average temperature is lower than 10℃ on November 10, it is moved to a cold storage with a constant temperature of 4℃ for low temperature treatment. Low temperature treatments are 0d, 14d, 21d and 28d.

[0023] Greenhouse management: After moving into the greenhouse, adopt temperat...

Example Embodiment

[0027] Example 2

[0028] The material used in this example is different from that of Example 1, which is four-year-old Luhehong (Peaonia.suffruticosa cv'Luhehong') of the 14d low temperature treatment group.

[0029] In the 14-day low temperature treatment group, 5-azaC was applied to smear the flower buds, and the effective concentration of 5'-azaC was 10-100 μmol / L, and the number of treatments was 1-7 times, once a day.

[0030] The peonies treated with different effective concentrations of 5'-azaC were moved into the greenhouse for morphological observation and recording, and the number of days required for bud germination, germination rate, final flower formation rate and flower formation quality were counted. The standard of germination rate is that the terminal bud scales crack and the flower bud grows more than 3cm in height. The standard of flower formation is that the flower has opened or the flower bud is swollen to the extent that it can bloom. The judgment of f...

Example Embodiment

[0032] Example 3

[0033] The material used in this example is four-year-old Luhehong (Peaonia.suffruticosa cv'Luhehong') of different low temperature treatment groups in Example 1.

[0034] In different low temperature treatment groups, 5-azaC was applied to smear the flower buds, and the effective concentration of 5'-azaC was 50 μmol / L, and the application frequency was 5 times, once a day.

[0035] The peonies treated at different low temperatures were moved into the greenhouse for morphological observation and recording, and the number of days required for bud germination, germination rate, final flower formation rate and flower formation quality were counted. The standard of germination rate is that the terminal bud scales crack and the flower bud grows more than 3cm in height. The standard of flower formation is that the flower has opened or the flower bud is swollen to the extent that it can bloom. The judgment of flower quality needs to comprehensively evaluate the h...

Abstract

The invention discloses a method for promoting off-season peony flower bud sprouting and branch growth, and belongs to the field of plants. The method includes performing low-temperature treatment onpeony for 14 days and then smearing the peony with 50 mumol/L 5-azacytidine solution for 5 days continuously; and smearing once a day. According to the method, the methylation level of peony flower bud can be reduced, dormancy can be relieved in advance, branches can sprout and grow, the flower forming rate, the height of branches and the length of leaves can be improved, and the flower forming quality can be obviously improved.

Description

technical field [0001] The invention belongs to the field of plants, and in particular relates to a method for promoting flower bud germination and branch growth of out-of-season peony. Background technique [0002] Peony is a characteristic famous flower native to China. It has high ornamental value, medicinal value and oil value, etc., and occupies an important position in the national flower industry. In order to advance its normal flowering period in April and May to the Spring Festival to add to the festive atmosphere, people have urged peonies to bloom during the Spring Festival since the Tang Dynasty, and it has now developed into one of the main contents of the peony industry. Every year, more than 2 million peonies are used to promote flowering in winter across the country, with an annual output value of more than 200 million yuan. Due to the lack of understanding of the mechanism of dormancy release in peony flower buds and the inability to correctly grasp its bio...
