Types of Temporary Immersion Systems Used in Commercial Plant Micropropagation

Area of Science:

• Plant Biotechnology
• Horticultural Engineering

Background:

• Temporary immersion systems (TIS) are crucial for plant micropropagation.
• Recent innovations have focused on TIS design, components, and air replacement methods.

Purpose of the Study:

• To review market-available TIS types.
• To highlight the advantages and disadvantages of each TIS design for plant micropropagation.

Main Methods:

• Review of technological innovations in TIS design and manufacturing.
• Analysis of component modifications, materials, and air replacement techniques.
• Comparison of different TIS operational principles and their impact on biological yield.

Main Results:

• Innovations include changes in size, fitting, component replacement, and manufacturing materials.
• Shift from compressor-based air replacement to tilting/rotation of culture bottles.
• Modified TIS designs aim to increase shoot yield and reduce production costs.

Conclusions:

• Despite design changes, the core principle of programmable explant immersion remains.
• Different TIS designs present distinct advantages and disadvantages.
• Species-specific validation is essential to determine the most effective TIS for plant micropropagation.
