Embodiment 1

[0024] Embodiment 1: a kind of method of Gerbera chrysanthemum rapid propagation cultivation and annual production fresh flowers comprises the following steps:

[0025] 1. Select an excellent single plant with pure red color, large flowers, and strong growth among the imported and cultivated gerbera, cut the stem tip 1-2 cm as the explant, wash it with tap water for 5 minutes, and use 70% alcohol on the clean workbench Soak for 15 minutes, then treat with 0.1% mercuric chloride + 0.5% Tween 20 for 10 minutes, rinse with sterile water for 5 times, and inoculate in the primary culture medium.

[0026] 2. After 1-2 adventitious buds grow on the explants, they are transferred to the new primary medium for culture.

[0027] 3. When the adventitious buds grow to 2-3cm, cut the buds from the explants and transfer them to the subculture medium for rapid propagation, and reach a certain number after 6 generations of continuous subculture.

[0028] 4. Cut off a single plant with a seed...

[0034] Embodiment 2: a kind of method of Gerbera chrysanthemum rapid propagation cultivation and annual production fresh flowers, comprises the following steps:

[0035] 1. Select an excellent single plant with pure red color, large flowers, and strong growth among the imported and cultivated gerbera, cut the stem tip 1-2 cm as the explant, wash it with tap water for 5 minutes, and use 70% alcohol on the clean workbench Soak for 15 minutes, then treat with 0.1% mercuric chloride + 0.5% Tween 20 for 10 minutes, rinse with sterile water for 5 times, and inoculate in the primary culture medium.

[0036] 2. After 1-2 adventitious buds grow on the explants, they are transferred to the new primary medium for culture.

[0037] 3. When the adventitious buds grow to 2-3cm, cut the buds from the explants and transfer them to the subculture medium for rapid propagation, and reach a certain number after 6 generations of continuous subculture.

Embodiment 3

[0044]Embodiment 3: a kind of method of Gerbera chrysanthemum rapid propagation cultivation and annual production fresh flower, comprises the following steps:

[0045] 1. Select an excellent single plant with pure red color, large flowers and strong growth from the imported gerbera, and inoculate it in the primary culture medium after routine disinfection.

[0046] 2. After 1-2 adventitious buds grow on the explants, they are transferred to the new primary medium for culture.

[0047] 3. When the adventitious buds grow to 2-3cm, cut the buds from the explants and transfer them to the subculture medium for rapid propagation, and reach a certain number after 6 generations of continuous subculture.

[0048] 4. Cut off a single plant with a seedling height of 5 cm, and transfer it to the rooting medium for rooting culture. In about 10 days, 98% of the seedling bases grow 2-5 adventitious roots.

[0049] 5. Take out the seedlings and wash off the residual culture in clean water, ...

Abstract

The invention belongs to the technical field of gardens, especially in the direction of tissue culture and chemical regulation, and relates to a method for rapid propagation and annual production of gerbera chrysanthemums. The method comprises the following steps: primary culture, subculture, rooting culture, transplanting and planting, wherein the primary culture, subculture and rooting culture all use basic culture medium and plant growth regulator as culture substrate. This method sets a new basal medium for gerbera, and using the basal medium in combination with plant growth hormone can effectively improve the culture efficiency and the success rate of tissue culture, and at the same time effectively shorten the time required for each step, and the colonization can survive The rate is high, the time required for flowering after planting is short, and the flower production rate per plant is high.

Description

technical field [0001] The invention belongs to the technical field of gardens, especially in the direction of tissue culture and chemical regulation, and relates to a method for rapid propagation and annual flower production of gerbera. Background technique [0002] Gerbera is a genus of Gerbera in the Asteraceae family. Perennial herbaceous flowers, together with gladiolus, carnations, roses, and chrysanthemums, are known as the world's top five fresh cut flowers. Originating in southern Africa, my country began to introduce species in the 1980s, but the cultivated species were completely imported from abroad, which greatly restricted the development of gerbera as the fifth largest cut flower in my country. [0003] Gerbera chrysanthemum traditional propagation methods are seed propagation and branch propagation. During the seed propagation process, due to the inconsistency of the maturation period of the pistil and the stamen, it causes self-fertilization. The seeds prod...
