Embodiment 1
[0029] A kind of method that the seed of spring cuckoo germinates quickly and becomes seedling:
[0030] (1) Seed preparation
[0031] In mid-to-late November, when the capsules of the spring cuckoo 'Purple Butterfly' are mature, but they are green capsules that have not yet cracked, they are picked, soaked in detergent water for 20-30 minutes, and rinsed under running water for 1-2 hours. After gently brushing the dirt on the surface of the capsule with a soft brush, blot the moisture on the surface of the capsule with filter paper, and install it in a petri dish (no need to cover the lid of the petri dish). Put it in a container with silica gel desiccant indoors and dry it until the capsules crack naturally.
[0032] (2) Seed soaking treatment
[0033] Before soaking the seeds, peel off the cracked capsules, and there is no need to sterilize the spring azalea seeds. After removing impurities, pick mature and plump seeds and soak them in warm water at 20°C for 24 hours.

The invention discloses a method for promoting germination and sprouting of folium rhododendri daurici seeds. The method comprises the following steps: soaking folium rhododendri daurici seeds into water, and then disinfecting; after disinfection, inoculating the seeds into a culture medium to accelerate germination for culture; after germination and sprouting of the seeds, transplanting seedlings into a matrix for culture, wherein the culture medium is a 1 / 4MS culture medium containing 0.4-0.6mg / L of KT and 0.03-0.06mg / L of NAA, or the culture medium is a 1 / 4MS culture medium containing 1.8-2.2mg / L of GA3 and 0.03-0.06mg / L of NAA. According to the method disclosed by the invention, the folium rhododendri daurici seeds are arranged inside the culture medium for culture to promote germination and sprouting of the folium rhododendri daurici seeds, by adding hormone with an appropriate type and appropriate concentration into the culture medium, the germination time of the folium rhododendri daurici seeds is early, the folium rhododendri daurici seeds can reach high germination rate in a relatively short period of time, and the method has the advantage that the usage amount of the hormone is less compared with a conventional seed soaking method, so that the cost is saved.
Description
technical field [0001] The invention belongs to the field of plant biotechnology, and relates to a method for promoting the germination and seedling formation of spring azalea seeds. Background technique [0002] Rhododendron is a plant of the genus Rhododendron in the Rhododendron family (Ericaceae), and is one of the top ten famous flowers in my country. Rhododendron is a large genus, with about 1,000 species in the world, and the most in Asia, with about 850 species, of which there are more than 530 species in my country. There are many kinds of rhododendrons in my country, and the resources are abundant, and the differences between species are relatively large. Rhododendron for greening is a woody flower and a small evergreen shrub. According to the different flowering periods, it can be divided into spring cuckoo and summer cuckoo. Spring Rhododendron has high ornamental value, with large and colorful flowers, strong germination ability and resistance to pruning. Pl...
