Hormone discovered through tissue culture technique is cytokinin. Cytokinin was discovered by Skoog and Miller. The first cytokinin discovered was kinetin. This was isolated as a DNA degradation product. 

Apical dominance is a phenomenon in which central stem is dominant and lateral stems are suppressed. It is due to plant hormones auxin produced in the tip of the shoot. It promotes apical dominance and does not allow lateral / axillar buds to grow. Another plant hormone, cytokinin is responsible for having negative effect on the apical dominance. It promotes the growth of lateral buds.  

Cytokinin is a plant hormone which is involved in growth and development of plants. It is required for the cambial growth. Kinetin, a type of cytokinin promotes cell division. It induces formation of interfascicular cambium in plants.

Cytokinin is a plant hormone. It promotes cell division. It also delays the destruction of chlorophyll and protein. It shows delay of senescence in leaves. It is mostly produced in the root apex. Roots synthesize maximum amount of cytokinin hormone.

Cytokinin is a plant hormone which is involved in various physiological processes of plants. Zeatin is the most common type of naturally occurring cytokinin. It is found in maize. It is also found in the coconut milk. It promotes cell division.

Cytokinin is a plant hormone. It plays major role in cell proliferation and cell division. It also delays the destruction of chlorophyll and protein. During senescence, cytokinin levels are low. It delays in senescence of leaves when sprayed externally by delaying the destruction of chlorophyll and proteins in leaves

Cytokinin (CK) is a plant hormone. It promotes cell division and delays senescence in plants. It improves nutrient mobilization and thus delays leaf senescence. When applied externally, it mobilizes nutrients towards sites of application. It also promotes stomatal opening along with auxin hormone. It also breaks the dormancy of seeds and induce seed germination. 

Kinetin was first isolated from herring sperm DNA by Miller and Skoog. It is a type of naturally occurring cytokinin, a plant hormone. It promotes growth. It induces cell division or cytokinesis.

Cytokinin is a plant hormone that is synthesized in the root. It shows acropetal transport. It is exactly opposite to the basipetal transport of auxin hormone. Acropetal transport is the translocation of hormone towards the shoot apex.

Cytokinin is a plant hormone that is involved in various physiological processes. It is growth promoting hormone. It stimulates cell division or cytokinesis and hence the name was given. It is synthesized in high concentration in tissues that are dividing such as cambium.
