In addition, tissue cultures are useful for several other purposes listed below: 1. A plant breeder may use tissue culture to screen cells rather than plants for advantageous characters, e.g. Plant Tissue Culture is a process that uses plant material in a growing medium to grow new platelets. 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.

Initially, plant tissue culture was exploited as a research tool and Tissue culture is the culture and maintenance of plant cells or organs in sterile, nutritionally and environmentally supportive conditions (in vitro). tions. [9] In particular, the technology is useful for reducing plant breeding times or creating large amounts of plant material for research or distribution to farmers especially for crops important to food security in developing countries. 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 in vitro environment in which the plant material is grown is also ideal for the proliferation of microorganisms. Tissue culture produces clones, in which all product cells have the same genotype (unless affected by mutation during culture). Tissue culture plants are characterized by disease free growth, a more fibrous, healthier root system ,a bushier branching habit ,and a higher survival rate.

Factors affecting explant’s tissue culture response are (1) genotype, (2) physiological stage of donor plant, (3) explant source, (4) explant age, (5) explant size, (6) explant position in donor plant and (7) explant density. Plant tissue culture is a collection of techniques used to maintain or grow plant cells, tissues or organs under sterile conditions on a nutrient culture medium of known composition. We have already briefly considered the concepts of plasticity and totipotency. One advantage to tissue culture is that thousands of identical plants can be pro-duced from a small piece of plant tissue. Plant material is extremely important for the success of tissue culture studies [4].
