Ring peeling Cuttage technique of Rose-Diagram of Rose girdling Propagation

Ring peeling is ring peeling, that is, after peeling off the root, the nutrients on the trunk will not flow back to the root in autumn and winter. In the spring, the plants sprouted and the nutrients from the roots were transported upwards. By the time the wound peeled off last year healed, the flowers on the tree had already bloomed and the young fruit was ready. Girdling can temporarily increase the accumulation of carbohydrate above the ring and ring cut, and decrease the auxin content, so as to inhibit the vegetative growth of new shoots in the same year, promote reproductive growth is beneficial to flower bud formation and increase fruit setting rate. This practice is often adopted on old trees.

Girdling cuttings are conducive to adventitious root cuttings, with a girdling width of 5 mm to 7 mm. Before cutting, blister cuttings, such as persimmon and walnut, should be fully soaked in clean water and changed many times to soak the tannins in the body to facilitate the rooting of cuttings.

Among the many propagation methods of rose, the ring peeling cutting propagation method of rose is also commonly used, and the survival rate of this method is relatively high. For some varieties that are not easy to cut, after cutting off the residual flowers in the high temperature and rainy season from July to August, peel off a circle of skin 3 mm wide under the leaf base of the third and fourth leaf nodes. The peeled part is shielded from the light by using the branches and leaves of this plant or other plants, not in direct sun, and the healing can occur after a week. Two or three weeks later, when the callus grew into a semicircle and slightly yellowish, the branches were cut off and inserted into fine sand or ordinary culture soil, placed in semi-shade, and the roots could grow normally after two weeks.

The method of cutting after equal length healing tissue was used by ring peeling technique.

A branch can be peeled into multiple nodes according to the length of the cuttage. The peeled opening should be wrapped in opaque tape.

Grow healing tissue.

Cut it.

First use disposable cups to make petri dishes.

It sprouted after a period of cultivation.

See the benefits of disposable cups, you can observe the rooting.

The first picture shows that the peeled mouth is wrapped in opaque tape. It is because the healing tissue grows better after the bag is protected from light and wind. Compared with the picture above, the two were peeled off at the same time on a branch, one with tape and the other without tape.

This is covered with adhesive tape, and the healing tissue is full and fresh.

This is not covered with duct tape, it is obvious that the healing tissue is not as long as duct tape.
