The following points highlight the three types of hormones which regulates the growth and development of plants. The hormones are: 1. Auxins 2. Cytokinins 3. Gibberellins. Hormone # 1. Auxins: Both naturally occurring and synthetic auxins are available and are widely used in cultures for clonal propagation work. Naturally occurring auxin is indole acetic acid (IAA). Synthetic ones are 2, [...]
In this article we will discuss about the role of auxins and cytokinins in culture medium. Effective, speedy growth and desirable morphogenesis in tissue culture requires the presence of both auxins and cytokinins in culture medium. The relative concentration of auxins and cytokinins are often essential to bring about some kind of morphogenesis. Axillary shoot proliferation in some species may [...]
In this article we will discuss about the three main plant hormone signalling involved in differential development and other physiological process in plants:- 1. Cytokinin Signalling 2. Auxin Signalling 3. Gibberellin Signalling. 1. Cytokinin Signalling: Cytokininis have been registered as one of the key plant hormones involved in differential development and other physiological process in plants, such as cell division, [...]
