The method offers an advantage over other methods as it can be used to develop disease free plants from disease-rode plants by using their meristems (apical and axillary) as explants. Micropropagation techniques are of three types based on the way of propagation: first, the propagation from shoots with cytokinin like benzyladenine or kinetin; second, multiple shoot differentiation from dedifferentiating tissue, callus, with an auxin-like indole acetic acid; and finally, the embryo differentiation from callus. To study the respiration and metabolism of plants. in this . Plant Tissue Culture is an important facet of Biotechnology and in many cases it becomes a limiting factor for the fruition of the goals of Biotechnology. Plant tissue culture is the process of taking living tissue from a plant (for example a piece of a leaf, stem, flower, or even a seed) and growing that “explant” into a full plant in sterile conditions. The cells may be removed from the tissue directly and disaggregated by enzymatic or mechanical means before cultivation, or they In addition, tissue cultures are useful for several other purposes listed below: 1. The in vitro environment in which the plant material is grown is also ideal for the proliferation of microorganisms. Commercial tissue-culture laboratories are generally equipped with laminar flow hoods and autoclaves, and they operate using sterile techniques. Academia.edu no longer supports Internet Explorer.

The essential point as far as plant cell culture is concerned is that, due to this plasticity and totipotency, specific media manipulations canbe used to direct the development of plant cells in culture. This is a technique by which new plants can be raised by the use of plant parts or cells. Using the appropriate growing conditions for each explant type, plants can be induced to rapidly produce new shoots, and, with the addition of suitable hormones new roots. Plant Tissue Culture Terminology Adventitious---Developing from unusual points of origin, such as shoot or root tissues, from callus or embryos, from sources other than zygotes. Plant hormones rarely act alone, and for most processes— at least those that are observed at the organ level—many of these regulators have interacted in order to produce the final effect. The initial plant material is cultured and developed in a specific and tightly controlled environment. Once cleaned, the plant tissue goes in a dense nutrient culture which is typically an agar gel containing a carefully crafted nutrient, hormone and sugar mixture.
