The explant is treated with chemical sterilants (e.g., sodium hypochlorite, ethanol, or mercuric chloride) to kill surface microbes without damaging the plant tissue.
Agar is used to create a semi-solid surface. Plant Growth Regulators (PGRs): Auxins: Stimulate root growth. Cytokinins: Stimulate shoot growth. Applications in Modern Science Why is this technique so widely studied? plant tissue culture ppt pdf
Because plants inside culture vessels cannot photosynthesize efficiently, an external energy source is required. (at a concentration of 2% to 3%) is the most common sugar used. Gelling Agent
Once a sufficient number of shoots have developed, they are separated and transferred to a rooting medium. This medium typically contains a higher ratio of auxin to cytokinin to induce the formation of a healthy root system. Bookmark this guide
– The culture of plant cells whose cell walls have been removed enzymatically. Protoplasts can be fused to create somatic hybrids, making this technique important for genetic manipulation.
A high auxin-to-cytokinin ratio promotes root development. A high cytokinin-to-auxin ratio promotes shoot development. An intermediate balance induces unorganized callus growth. 4. Fundamental Techniques in Tissue Culture The explant is treated with chemical sterilants (e
Strict use of autoclaves, clean laminar hoods, proper explant bleaching, and occasional use of antibiotics/fungicides.
These file formats serve distinct purposes: are ideal for lectures, seminars, and step-by-step lab demonstrations, while PDFs serve as permanent handouts, protocol manuals, and research references. This article provides a comprehensive overview of PTC, explains the essential components of a winning presentation, and guides you on where to find (and how to use) the best resources.
Culturing the apical or axillary meristem dome. Because vascular connections are absent or underdeveloped at the absolute tip, this technique is universally deployed to eliminate viruses from infected mother plants.
