Question

способы вегетативного размножения кустарников.ОЧЕНЬ СРОЧНО!!!!!!!!!!

Answer 1

аналогично с деевьями и корнями

Кустарники размножаются черенками, семенами, отводками.

 

Answer 2

1.Самый простой способ вегетативного размножения — деление куста.Так размножают кустарники, имеющие много ветвей в основании куста и мочковатую корневую систему. К ним относятся калина, шиповник, ирга, арония, крыжовник, жимолость съедобная, смородина, малина .

2.Еще один простой способ — размножение с помощью горизонтальных отводков. Таким способом размножают многие ягодные кустарники: крыжовник, смородину, жимолость, а также актинидию. Ранней весной выбирают сильные однолетние ветви, укладывают их в заранее вырытые рядом канавки глубиной 5-8 см и присыпают землей.

3.Третий способ вегетативного размножения — одревесневшими черенками. Так размножают растения, у которых стебли после отделения от маточного куста могут образовывать при контакте с почвой придаточные корни. Легче всего окореняются черенки черной смородины, чуть хуже – красной и крыжовника, еще хуже — голубики,актинидии и жимолости. Черенки обычно заготавливают после листопада (после весенней нарезки они окореняются хуже) — нарезают их из одно- или двулетних ветвей. До весны их хранят в прохладных помещениях или под снегом.

Methods of Vegetative Propagation in Shrubs

Vegetative propagation is a method of plant reproduction that does not involve the production of seeds. Instead, new plants are generated from vegetative parts of the parent plant, such as stems, roots, or leaves. This process allows for the production of genetically identical offspring, which can be advantageous for maintaining desirable traits in horticulture and agriculture. Here are some common methods of vegetative propagation in shrubs:

1. Layering: Layering is a technique where a branch or stem of the parent plant is bent and partially buried in the soil while still attached to the parent plant. Over time, the buried portion of the stem develops roots, and once it has established a sufficient root system, it can be separated from the parent plant and grown as an independent shrub. Layering is commonly used for shrubs like roses and hydrangeas.

2. Cuttings: Cuttings involve taking a portion of a stem, root, or leaf from the parent plant and encouraging it to develop roots and grow into a new plant. There are different types of cuttings, including stem cuttings, leaf cuttings, and root cuttings. Stem cuttings are the most common and involve taking a section of stem with several nodes and leaves. The cutting is then placed in a suitable growing medium, where it develops roots and eventually grows into a new shrub. This method is widely used for propagating a variety of shrubs, including azaleas, boxwoods, and lilacs.

3. Division: Division is a method of vegetative propagation that involves dividing the parent plant into smaller sections, each with its own roots and shoots. This is typically done by carefully separating the root system of the parent plant into individual clumps or by dividing the above-ground portion of the plant. Each divided section can then be planted separately to grow into a new shrub. Division is commonly used for shrubs that form clumps or have a spreading growth habit, such as ornamental grasses and some flowering shrubs.

4. Grafting: Grafting is a technique where a portion of one plant, called the scion, is attached to the root system of another plant, called the rootstock. The scion and rootstock are carefully matched to ensure compatibility, and the two plant parts are joined together using various grafting techniques. Grafting allows for the combination of desirable traits from different plants, such as disease resistance or specific flower colors. It is commonly used in the propagation of fruit trees and some ornamental shrubs.

These are just a few examples of the methods used for vegetative propagation in shrubs. Each method has its own advantages and is suitable for different types of plants. It's important to note that the success of vegetative propagation can vary depending on the specific plant species and environmental conditions. If you have a particular shrub in mind, it would be helpful to provide more information so that I can provide more specific guidance.
