“…One of the advantages of tissue culture is the capacity to preserve germplasm in vitro for long periods without the large investments in land, labour, water, fertiliser, and pesticide that would be required for plantation-or nursery-based germplasm archives [42,[51][52][53]178,179]. In vitro storage can also delay the maturation of valuable clones, especially if their shoots or callus are stored under minimal-growth or nil-growth conditions [39,40,42,[180][181][182].…”

Eucalypts are among the world's most widely planted trees, but the productivity of eucalypt plantations is limited by their often-low amenability to true-to-type propagation from cuttings. An alternative approach to cutting propagation is tissue culture, which can be used to micropropagate valuable genotypes rapidly while simultaneously preserving germplasm in vitro. This review describes the use of tissue culture methods such as shoot culture, organogenesis, and somatic embryogenesis for micropropagating eucalypts. This review also discusses the use of cool storage, encapsulation, and cryopreservation methods for preserving eucalypt germplasm and delaying tissue maturation under minimal-growth conditions.

“…Better results were obtained by Capuana and Di Lonardo [21] in the storage of shoot cultures of C. sativa; they achieved survival percentages greater than 80% after 48 months at 8 • C. A storage temperature of 4 • C significantly decreases the survival percentages, only recovering 56% of the cultures after 12 months storage, and 0% survival after 24 months. Gomes et al [97] compared two techniques (synthetic seeds and slow growth storage) for the preservation of hybrid clones produced from controlled crosses between C. sativa × C. crenata and C. sativa × C. mollissima. The best treatment was achieved with synseeds stored for six months with sterile distilled water, and with slow growth storage with 0.22 M sucrose.…”

Castanea is a hardwood forest genus of considerable agro-economic importance for both timber and nut production. Chestnuts are one of the most significant nut crops in the temperate zone. However, this species is threatened by pollution, social factors, economical changes, and two major fungal diseases: ink disease (Phytophthora spp.), and chestnut blight canker (Cryphonectria parasitica). Similar to other wood species, chestnuts are difficult to propagate both generatively by seed and vegetatively by means of grafting or cuttings. Biotechnological methods such as in vitro culture have been developed in the last few years as an alternative to conventional vegetative propagation. Biotechnology plays a very important role not only in the propagation of selected individuals (being used at a commercial level), but also in its short-term preservation, and offers the possibility of preserving the propagated material in the medium-term (cold storage) or long-term using cryopreservation.
