How to reproduce orchids, how to reproduce orchids

Cymbidium grandiflora is commonly propagated by ramification, seeding and tissue culture.

1. Dividing propagation:

After flowering, the sprouts are in a short dormant period before the shoots have grown. Before dividing, the base should be properly dried, so that the roots of Cymbidium grandiflora are slightly whitish and soft, so that the roots are not easy to break during operation. Divide the mother plant into 2 3 tubes and a bunch of potted plants, grasp the false bulb during operation, do not touch the new shoots, and cut off the yellow leaves and rotten old roots.

2. Sowing and propagating:

It is mainly used for mass propagation and cross-breeding of native species. The seeds are small and easy to germinate under sterile conditions, with a germination rate of more than 90.

3. Tissue culture propagation:

The young shoots emitted from the base of the robust mother plant were selected as explants. Cut the bud segments into stem tips with a diameter of mm and inoculate on the prepared medium. Add 6 mg of benzylaminoadenine to MS medium for 52 days to form protocorms.

Protocorms are removed from the medium, cut into small pieces, and inoculated in MS medium supplemented with 6 mg of benzylaminoadenine and mg of naphthalene acetic acid to proliferate the protocorms. The protocorm was continued to be cultured in the proliferation medium, and the buds were formed at the top of the protocorm for about 20 days, and the roots were partially transformed at the bud base. After about 90 days, the differentiated plants grow complete seedlings with 3 or 4 leaves.

Hui orchid will germinate new shoots, can be propagated by ramification, and can also be propagated through tissue culture if there is technology (sincerely answer for you, please feel free to set it as "praise" Oh, there is nothing to lose to you, thank you!). ）

Plants that are propagated by raming should generally be planted for 2 3 years of strong seedlings, and the time for raming is generally suitable in March and April or September and October each year. The substrate needed for the ramets should be loose and fertile, breathable and drained, free of insect disease and pollution, and avoid heat, dryness and waterlogging. The pH of the soil should be in between.

Before use, it needs to be sun-dried or sterilized with drugs.

Dividing steps Depotting: The potted orchid used for branching propagation is tilted upside down, patted and shaken the pot, so that the plant and the substrate are gradually taken out together, and at the same time, it is necessary to pay attention to the protection of the leaves and roots.

Seedling: Raise the ground orchid used for branch propagation with tools from the ground and do not let the root system and bud points be harmed.

Segmentation: Find the dividing point between the orchid plants at the base of the false bulb and cut it with a pair of sterilized scissors. After dividing the orchid, there should be at least two plants.

Pruning: Cut off the dry leaf sheaths on empty roots, severed roots, rotting roots, dead leaves, and false bulbs, as well as leafless, shriveled, and rotten false bulbs.

Disinfection: After trimming, apply sulfur powder or charcoal powder to the wound shirt for disinfection and dry it properly.

The method of sowing and propagation is mainly applied in the mass propagation and cross-breeding of native species of Cymbidium. The seeds of Cymbidium are very small or hail lead, and the seed germination rate is more than 90% under sterile conditions.
