The concept of plant tissue culture was first proposed by in 1902, who is widely regarded as the father of plant tissue culture. Although he failed to cultivate cells due to a lack of proper nutrient media, his hypothesis paved the way for future breakthroughs: 1922 (Robbins and Kotte): Successfully cultured root tips.
The donor plant must be rigorously screened for health, vigor, and trueness-to-type. It is often maintained under controlled conditions to minimize initial systemic contamination. Stage I: Establishment of Sterile Culture (Initiation)
Agar or Gelrite to provide a solid or semi-solid support matrix for the tissue. plant tissue culture ppt pdf

Because plants are grown in climate-controlled laboratories, production is entirely independent of seasonal and weather variations. The concept of plant tissue culture was first
The process generally follows a sequential path to move from a parent plant piece to a field-ready plantlet:
Trace elements needed in minute amounts, such as Iron (Fe), Manganese (Mn), Zinc (Zn), Boron (B), Copper (Cu), and Molybdenum (Mo). Carbon Source It is often maintained under controlled conditions to
Culture of isolated organs like embryos (embryo culture), roots, or endosperm.
– Autoclaving parameters, surface sterilization chemicals, UV radiation.
Imagine a forest where a single tree can give rise to a million identical clones, or a rare orchid on the verge of extinction being brought back to life from a tiny piece of leaf. This is not science fiction; it is the reality of . Often referred to as "micropropagation," this technique is one of the most fascinating and impactful biotechnologies of the 20th century. It is the art and science of growing an entire plant from a minuscule piece of tissue—sometimes no larger than a speck of dust—under sterile, controlled conditions.
Plantlets are carefully removed from the agar medium to avoid root damage. They are transferred into small pots containing a sterile, porous mix (like peat, perlite, or vermiculite).
