1. Apical dominance: By removing the apical meristem (the tip of the shoot), the lateral buds are able to grow and develop, leading to branching and bushier growth.
2. Pruning: By selectively removing parts of the plant, such as shoots or branches, the growth of the remaining meristems can be directed to specific areas, promoting desired growth patterns.
3. Grafting: By joining the meristematic tissues of two different plants, new growth can be directed and controlled, leading to the development of new varieties or improved traits.
4. Hormone treatments: By applying specific plant hormones, such as auxins or cytokinins, the growth and development of meristems can be manipulated to promote root or shoot growth, flowering, or other desired outcomes.
5. Tissue culture: By culturing meristematic tissues in a controlled environment, researchers can manipulate the growth and development of plants, leading to the production of genetically identical clones or the regeneration of whole plants from small tissue samples.

Physical Manipulations:
- Grafting: Joining tissues from different plants to induce meristematic activity and initiate new organ formation.
- Air layering: Stimulating root meristems at the cut end of a branch while still attached to the parent plant.
- Layering: Bending or burying part of a stem to promote root meristematic activity and form new plants.
- Micropropagation: Using tissue culture techniques to propagate plants from small explants containing meristematic cells.
- Somatic embryogenesis: Inducing somatic cells to differentiate into embryos that give rise to new plants.
Chemical Manipulations:
- Hormone treatments: Applying growth hormones (e.g., auxins, cytokinins) to stimulate or inhibit meristematic activity.
- Anti-auxin treatments: Blocking auxin signaling to promote meristematic proliferation.
- Chemical mutagenesis: Exposing meristems to mutagens (e.g., radiation, chemicals) to induce genetic mutations that may affect meristematic activity.
- Epigenetic modifications: Altering the gene expression patterns of meristems through DNA methylation or histone modification.
Genetic Manipulations:
- Transgenic plants: Introducing foreign genes into meristems to alter their genetic makeup and modify meristematic behavior.
- CRISPR-Cas9 genome editing: Precisely modifying the genome of meristems to introduce or remove specific genes involved in meristematic activity.
- RNA interference (RNAi): Silencing specific genes in meristems using RNA molecules to interfere with gene expression.
Other Methods:
- Environmental cues: Providing specific environmental conditions (e.g., light, temperature, nutrients) to influence meristematic activity.
- Mechanical stress: Applying physical forces (e.g., bending, stretching) to meristems to stimulate or inhibit their activity.
- Micromanipulation: Using precision instruments to manipulate individual meristematic cells under a microscope.
