What is Acclimation in Plant Tissue Culture?
Acclimation is defined as adapting your tissue culture plantlets to a greenhouse environment and preparing them for natural outside conditions.
As you know tissue culture plants are grown in a test tube or vessels in a completely controlled disease-free environment. Therefore, the chances of their survival in a highly fluctuating outside environment are reduced. Further, when they are transferred to soil, they become highly sensitive to diverse microbial attacks. This reduces the output or overall healthy plants you receive at the end of the process.
Thus, to increase the yield and survival of plants it’s necessary to properly harden the plants and slowly prepare them for what they will have to face after being transferred to natural conditions.
The ability to transfer tissue-cultured plants from a controlled, sterile environment to the field with minimal cost and a high survival rate is crucial for the commercial success of such plants.
In this article, we discuss more of the tips for acclimating your tissue culture plants properly and the factors that can affect the acclimation process.
Why is Acclimation Necessary?
Here are some reasons why acclimating tissue culture plants is necessary:
- Tissue culture plants are grown in a sterile and controlled environment, so they lack the natural resistance to environmental stressors and pathogens that plants grown in soil have.
- Tissue culture plants are often grown in a nutrient-rich gel-like medium, so they may not be used to soil conditions.
- Acclimation helps plants to adjust to the external environment, including light levels, temperature, humidity, and wind, which can affect their growth and survival.
- Acclimation can help tissue culture plants develop stronger roots, stems, and leaves, which will improve their ability to absorb nutrients and water from the soil.
- Proper acclimation can help tissue culture plants survive the transfer from the lab to the field or greenhouse, and improve their chances of long-term survival and growth.
Factors That Affect Acclimation of Tissue Culture Plants
Factors that affect the acclimation of tissue culture plants include:
- Humidity levels: Tissue culture plants are accustomed to high humidity levels, so when transferring to a greenhouse or field environment, it's important to gradually reduce humidity levels to prevent water loss and stress on the plant.
- Light intensity: Tissue culture plants require low light intensity, so exposing them to high-intensity light in a greenhouse or field environment can cause stress and damage to the plant. Gradual exposure to increasing light intensity can help the plant acclimate.
- Temperature: Tissue culture plants are often grown in controlled, aseptic environments with consistent temperatures. When transferring to a greenhouse or field environment, temperature fluctuations can cause stress and affect plant growth and survival.
- Nutrient availability: Tissue culture plants are often grown in nutrient-rich media, so when transferring to soil or potting mix, it's important to ensure the plant has adequate nutrient availability to support growth and acclimation.
- Plant variety: Different plant varieties have varying growth requirements, so the acclimation process may need to be customized based on the specific plant variety.
Best Tips To Acclimate Your Tissue Culture Plants
Here’re some tips to properly acclimate your plants:
- To acclimate tissue culture plants, they need to be transferred from a lab environment to a greenhouse with similar conditions.
- Plantlets should be transplanted into a potting mix with an inorganic nutrient solution, such as peat, vermiculite, soil, or sand.
- For a few days, the culture vessels can be kept in the greenhouse with loose lids.
- Shade should be provided for 3-6 days under diffused natural light to help the plantlets adapt to their new environment.
- Gradual exposure to greenhouse and field conditions is recommended in 2-3 phases.
- To adapt plants from high to low humidity, keep them in the shade with loose plugs for a week or two and then transfer them to pots with sterile soil and sand, covered with polybags.
- Preconditioning rooted plantlets in sucrose solutions (20-30g/L) before transferring them to a potting mix can increase shoot growth.
- Adding anti-transpirants like 'paclobutrazol' to the rooting medium can improve stomata functioning, thicken roots, and reduce wilting.
- The acclimation process needs to be customized for each plant variety based on its specific growth requirements.
The steps will prepare the tissue culture plants to initiate photosynthetic activity and prepare them to survive in the natural environment.
