Plant Physiology Experiments Tissue culture —— Media preparation
Tissue Culture a technique which small tissue pieces or organs are removed from a donor plant and cultured aseptically on a nutrient medium By manipulating the chemical composition of the nutrient medium and other environmental parameters, the growth and development of the tissues in culture can be directed into different channels
Tissue Culture • A technique which small tissue pieces or organs are removed from a donor plant and cultured aseptically on a nutrient medium. • By manipulating the chemical composition of the nutrient medium and other environmental parameters, the growth and development of the tissues in culture can be directed into different channels
Totipotency An ability to dedifferentiate demonstrates that differentiated plant cells retain all the genetic information required for the development of a complete plant, a property

The BackgroundⅡ Folke Karl Skoog su(崔澂) Both organ formation and subsequent development are brought about by quantitative changes in amounts and interactions between nutrients and growth factors which are essential for growth of all cells, so that the pattern of development is determined by the relative supplies.. of these materials at particular loci http://www.nap.edu/readingroom.php?book=biomems&page=fskoog.html

Why do Plant Tissue Culture? 1. Fast propagation and virus removal. 2. Anther and Pollen culture. 3. Somaclonal variation and mutant separation. 4. Protoplast culture and cell hybridation. 5. Plant artificial seed, or man-made seed. 6. Give a continuous supply of young plants to produce secondary metabolite. 7. Plant ‘tissue banks*’ can be frozen, then regenerated through tissue culture.
