A major problem of production plants is a disease which can be caused by a fungus. Bacteria or viruses, so the plants produced by plant tissue culture.Be free from fungi and bacteria, the first due in tissue culture dishes, will show symptoms of contamination (contamination), it will show. Colony of the bacteria or spores, visible with the naked eye. Which can hold out and removal of contamination incidents section erases viruses which have a very small particles can survive when living in another type of organism cells only. The plant is the contamination of the virus will not show symptoms of contamination on food, but I know when symptoms occurred on plants only. So before you make tissue culture plants must include the selection and monitoring of tissue or part of the plant, so most virus-free. By using parts of the meristem Which is the tissue that sits at the tip of childbearing, or the Cup tissue pha (embryo) in which the seeds of such tissue there is no piped water (xylem) and food (phloem) that will be in contact with other parts of the plant, so the particles of the virus so it cannot access.
