Microbes may come from glass vials, instruments, nutrient medium and also from the plant material. # Discuss the applications of Plant Tissue Culture in Agriculture, Horticulture & Industry. Single cells, plant cells without cell walls (protoplasts), pieces of leaves, stems or roots can often be used to generate a new plant on culture media given the required nutrients and plant … Tissue culture produces clones, in which all product cells have the same genotype (unless affected by mutation during culture). Plant Tissue Culture---The growth or maintenance of plant cells, tissues, organs or whole plants in vitro. Tissue culture plants are characterized by disease free growth, a more fibrous, healthier root system ,a bushier branching habit ,and a higher survival rate. The sterile explants are then usually placed on the surface of a sterile solid culture medium but are sometimes placed directly into a sterile liquid medium, particularly when cell suspension cultures are desired. Save my name, email, and website in this browser for the next time I comment. The cultivation process is invariably carried out in a nutrient culture medium under aseptic conditions. Applications: Plant tissue culture is an essential component of plant biotechnology. The composition of the medium, particularly the plant hormones and the nitrogen source (nitrate versus ammonium salts or amino acids) has profound effects on the morphology of the tissues that grow from the initial explant. Nutritional requirements 57-70 6. The cultivation process is invariably carried out in a nutrient culture medium under aseptic conditions. These conditions include the proper supply of nutrients, pH medium, adequate temperature, and proper gaseous and liquid environment. Source | Credits | Picture Credits: NCERT General Science Plant Tissues Plants are stationary or fixed – they don’t move. As shoots emerge from culture, they may be sliced off and rooted with auxin to produce plantlets which, when mature, can be transferred to potting soil for further growth in the greenhouse as normal plants.
