Understanding these pros and cons allows researchers and growers to select the sterilization method that aligns with their specific needs and resources, ensuring a successful and contaminant-free plant tissue culture environment.

Key Factors in Tissue Culture

In the heart of plant tissue culture there are a few large determining factors that affect growth. We’ll focus on light, environment, and culture media formulations for now.

Lighting in Plant Tissue Culture

The light intensity typically observed for plants in tissue culture is around 50-110 u/mols. The lighting is made up of a mixture of red and blue light. Lighting for tissue culture plants do a few things.

    • Optimal Growth: The right quality and quantity of light are crucial for promoting the overall growth and development of tissue culture plants.

    • Photosynthesis Boost: Adequate light ensures an efficient photosynthesis process, where plants convert light energy into essential nutrients, fostering health and vitality.

    • Morphogenesis Influence: Light plays a pivotal role in shaping the morphology of tissue culture plants, influencing factors such as leaf size, stem length, and overall structure.

    • Regulating Metabolism: Quality light regulates plant metabolism, influencing the production of secondary metabolites and enhancing the overall quality of the cultured plants.

Environment for tissue culture plants

A carefully controlled environment is foundational for the success of tissue culture, safeguarding against contamination, regulating temperature and humidity, and ensuring optimal air quality for plant development.

    • Sterile Conditions: A controlled and sterile environment is paramount to prevent contamination, ensuring the health and purity of tissue culture plants.

    • Temperature Regulation: Maintaining an optimal temperature range is crucial for the metabolic processes of plants, impacting growth rates and overall development.

    • Humidity Control: Precise humidity levels contribute to the prevention of desiccation and water stress, supporting the health and vitality of tissue culture plants.

    • Air Quality: Adequate ventilation and air circulation are essential for preventing the buildup of ethylene and other harmful substances, promoting a healthy growth environment.

Tissue Culture Media Components

Culture media is by far one of the most influential factors that will decide your culture’s success. Some of the inputs that proper media formulation takes into consideration are:

    • Nutrient Supply: Culture media formulations provide essential nutrients necessary for the growth and development of tissue culture plants, acting as a tailored nutritional source.

    • Hormonal Balance: The precise combination of hormones in the culture media influences various physiological processes, such as cell division, elongation, and differentiation, shaping the plant’s growth pattern.

    • Carbohydrate Supply: Tc plants lack the ability to photosynthesize, supplementing carbohydrates in the media provide the energy required for essential metabolic processes, cell growth, and differentiation.

    • pH Regulation: Maintaining an optimal pH level in the culture media is crucial for nutrient uptake, enzymatic activity, and overall plant health, influencing the success of tissue culture.

The Stages of Plant Tissue Culture

Plant tissue culture typically involves 7 stages to successfully propagate and cultivate plants in a controlled environment. Some stages can be combined or omitted depending on the plant being cultured, and the goal in mind for the explant.

Explant Selection

This marks the beginning of the tissue culture process, involving the selection and collection of the explant (the tissue to be cultured), which can be a part of the plant like a leaf, stem or node.

Surface Sterilization

The explant undergoes thorough surface sterilization to eliminate any contaminants. This is crucial to maintain aseptic conditions throughout the culture process.

Establishment

The sterilized explant is then introduced to a nutrient-rich culture medium containing essential nutrients, carbohydrates, and growth regulators. Here, the explant is encouraged to form callus, an undifferentiated mass of cells.

Multiplication

Once the callus is established, it is subcultured to promote the multiplication of cells. This stage is crucial for obtaining a sufficient number of cells for further development.

Shoot Formation

From the multiplied cells, shoots are induced. This is often achieved by manipulating the concentrations of growth regulators in the culture medium. If the explant starting material are nodes, shoot formation can begin immediately and not require a callus phase until the next phase, rooting. 

Rooting

The developed shoots are transferred to a medium that encourages the formation of roots. This stage is essential for the plant to develop a complete, functional structure.

Acclimatization

Finally, the rooted plantlets are acclimatized to normal environmental conditions. This involves gradually exposing them to the external environment, preparing them for transfer outdoors, indoors, or a greenhouse.
