Abstract Slow growth-storage, for up to 10 months, has been achieved for Eucalyptus grandis shoot cultures by either the addition of 10 mg l−1 abscisic acid to the growth medium or by the halving of nutrient supply (half MS) and removal of exogenous plant growth regulators. Reduction of light intensity or the addition of mannitol to the media were less effective in reducing growth rate. Isolated in vitro axillary buds encapsulated in calcium alginate and stored under low temperature and low light intensities survived for up to 3 months without loss in viability. Storage of such encapsulated fresh axillary buds at higher temperature resulted in a loss in viability. These methods have immediate applications to forestry breeding and clonal programs.
