In vitro storage of Eucalyptus grandis germplasm under minimal growth conditions.
TLDR
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 and removal of exogenous plant growth regulators.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.read more

TL;DR: ABA can act as anti-transpirant during the acclimatization of tissue culture-raised plantlets and reduces relative water loss during the ex vitro transfer of plantlets even when non-functional stomata are present.

Maturation and related aspects in clonal forestry—part II: reinvigoration, rejuvenation and juvenility maintenance
TL;DR: Methods for delaying the maturation of juvenile plants and for reducing the ontogenetic or physiological age of more-mature plants are examined and research areas in maturation that could lead to more-effective methods for establishing high-productivity plantations are identified.

Encapsulation of shoot tips of guava (Psidium guajava L.) for short-term storage and germplasm exchange
TL;DR: Shooting tips obtained from in vitro grown plantlets of guava were encapsulated in calcium alginate beads for short-term storage and germplasm exchange and regrowth ability was affected by medium strength and sucrose concentrations in the medium.
