Abstract: Sugarcane healthy seedlings or seedcanes are those sterilized by hot water treatment or axillary shoot tip culture, including axillary plantlets, asexual seedcanes for propagation or commercial production, which are produced under strict isolation conditions and meet certain criteria. In recent years, a temporary immersion bioreactors system(TIBs)has been developed and applied, which speeds up the multiplication of the healthy seedlings, improves the multiplication coefficient, and reduces the labor requirement. More recently, a new technique so-called ‘Plene’ has been developed, which substantially reduces the seedcane rate, and is good for mechanical operation so reducing the planting cost.
