Reproductive experience of cut rose

There are three main propagation methods of cut rose: cutting, grafting and tissue culture.

1. Cuttage propagation. It is mainly used for varieties that are easy to root, such as florets, and should be propagated by cuttings. Some large flower varieties are not easy to take root, especially yellow and white lines are difficult to root and are not often used. It is suitable for cuttage propagation in spring and autumn. Cuttings choose sturdy branches that have been cut off or not, keep them fresh in time after cutting, to prevent water loss, cut the branches into 7-10 cm cuttings, the upper cut mouth is 0.1-0.3 cm near the base of the bud, cut off the two leaves below the branch segment, leave two leaves above, leave 2-4 leaflets on each leaf, and cut the rest. Then at the bottom of the cuttings straight below the bud, opposite to the bud, cut 1 knife with a 45 °oblique cut with a blade, and then dip it with 200 mg. M liter of acetic acid, inserted into the seedbed with a depth of 1? M2-1? M3, plant line 4-5 cm, compacted and watered. The best substrate is vermiculite and perlite, upper buckle arch shed, moisturizing and heat preservation, about 20 ℃. It can take root after 15 days, and the seedlings can be transferred after 30 days, and the seedlings can be prepared by strengthening light and fertilizer and water management.

2. Grafting propagation. Rootstocks with developed root system, exuberant growth, disease resistance and cold resistance are selected as rootstocks, the rootstocks are commonly used as rootstocks, rootstocks are propagated by cutting method, and seedlings can also be grafted. Grafting is usually done by bud grafting, branch grafting, root grafting and so on.

3. Tissue culture and rapid propagation of rose. The young stem segment was used as explant, axillary bud culture and stem segment as subculture, and rose seedlings were propagated rapidly.
