Description of Plant Tissue Culture Agar

Agar-Agar Powder Plant Tissue Culture Grade, also called Plant Tissue Culture Agar, due to its high gel strength and low mineral content, is specially designed for the preparation of substrates for the cultivation and development of plants in vitro, for preparing semi-solid and solid plant tissue culture media.

The use of agar as a tissue culture agent has been around for several years due to its strength as a gel, minimal mineral content, and transparency. Cultivating plants in vitro requires following a series of rigorous steps, including providing the culture with a suitable growth medium. As interest in cultivating plants, fruits and flowers continues to grow, the simplicity of the tissue culture process is increasingly preferred by home growers and small-scale cultivators. And as interest in the tissue culture process grows, so does the curiosity about agar and DIY tissue culture kits.

What is Different Between Bacteriological Agar and Plant Tissue Culture Agar?

The main differences among different agar products are due to the impurities, their level, and their composition.


Agar has been widely used since it has convenient gelling properties and stability during tissue culture. In all media used for the invitro culture of plants, agar is the major source of unknown variations.

You can use both bacteriological agar and plant tissue culture agar for plant tissue culture, Both types would certainly give results.

However, plant tissue culture grade agar is now available from various companies. It's always better to use it.
