Tissue culture at home: realistic guide

Plant tissue culture (micropropagation) is the in-vitro propagation of plant material in sterilized growing medium, usually under artificial lighting in a laboratory setting. Per University of Florida IFAS Extension, commercial tissue culture produces millions of disease-free plants annually --.

Plant tissue culture (micropropagation) is the in-vitro propagation of plant material in sterilized growing medium, usually under artificial lighting in a laboratory setting. Per University of Florida IFAS Extension, commercial tissue culture produces millions of disease-free plants annually — orchids, banana, ferns, strawberries, potatoes — by multiplying small explant pieces (shoot tips, nodes, leaf sections) in sterile nutrient agar medium.

Home-scale tissue culture is possible. It is not a weekend project. This guide explains what the technique actually requires and helps you decide if it is worth pursuing.

What tissue culture is and isn't

Per NC State Extension, tissue culture encompasses:

• Micropropagation: Multiplying plants by culturing shoot tips or nodal segments on agar
• Meristem culture: Producing virus-free plants by culturing the shoot apical meristem (too small and technical for home use)
• Callus culture: Inducing undifferentiated cell growth, then differentiating it into shoots (laboratory technique; very difficult without plant growth regulators)
• Somatic embryogenesis: Producing embryos from vegetative cells (commercial laboratory technique)

Home tissue culture almost always means nodal micropropagation: culturing shoot tips or nodal explants to multiply a known genotype under sterile conditions.
