Tissue culture, also known as micropropagation, is a propagation method used to produce plants under sterile conditions. This process should take 20 minutes or less. Multiplication phase – Re-division of the explant in the tissue culture medium, producing multiple shoots. Gibco Cell Culture Basics is an introduction to cell culture, covering topics such as laboratory setup, safety, and aseptic technique. This type of culture will usually identify the bacterial species of the infection, and help steer antibiotic therapy. After the hardening process, plantlets are transferred to either the green house or the field conditions outside. In an actual laboratory setting, there are certain important steps that are not necessarily applicable in a virtual lab: 1. Thanks to all authors for creating a page that has been read 85,450 times.
