What Are the Advantages and Disadvantages of Plant Tissue Culture? Tissue culture is an aseptic in vitro culture of animal or plant cells in a precisely controlled environmental condition. Practical Applications of Plant Tissue Culture: The use of plant cells to generate useful products and/or services constitutes plant biotechnology. Tissue culture is a technique in which fragments of plants are cultured and grown in a laboratory. Since plant tissue culture is done in germs free environment, we get disease fee plants by the micropropagation. Figure 2. Strawberry image by Minoru from Fotolia.com. -each cell has the capacity to regenerate the entire plant. Tissue culture is the method of ‘in vitro’ culture of plant or animal cells, tissue or organ – on nutrient medium under aseptic conditions usually in a glass container. Plant Tissue Culture, Applications and Advantages EUROPEAN ACADEMIC RESEARCH - Vol. High profit because of the high benefit to cost ratio. Advantages and Disadvantages of Cell / Tissue Culture. The plantlets are used for the following purposes. By this technique living cells can be maintained outside the body of the organism for a considerable period. -ability to initiate cell division from almost any tissue of the plant. After a few weeks, new roots develop and a new plant grows. The unique feature of tissue culture propagation of bananas is the maturity of the crop earlier in the season. Put as simply as possible, micropropagation is where you take tissue from a plant to produce an identical plant (grown in lab conditions), the idea being that you can produce large quantities of these identical plants in a short space of time. Plants grown in a lab can’t just immediately go into a greenhouse or field; it’s a delicate process. Conditions that limits its use include: It is very expensive, and can have a labor cost of more than 70%; A monoculture is produced after micropropagation, leading to a lack of overall disease resilience, as all progeny plants may be vulnerable to the same infections. It is widely used to produce clones of a plant in a method known as micropropagation. … The setting up of a plant tissue culture laboratory is very expensive including it's machines and reagents 2. Advantages: 1. A plant breeder may use tissue culture to screen cells rather than plants for advantageous characters, e.g. Different hormone mixtures will trigger various stages of development for the tiny culture. Shoot multiplication usually has a short cycle (2-6 weeks) and each cycle results in logarithmic increase in number of shoots. Disadvantages of Tissue Culture Propagation of Banana Agriculture Farming. It makes use of parts of a plant to generate multiple copies of the plant in a very short duration.
