Mycorrhizal synthesis between Pisolithus arhizus and adult clones of Arbutus un...
Gomes, Filomena; Machado, Helena; San Martin, Esteban; Portugal, A.; Canhoto, J. M.Arbutoid mycorrhizae were synthesized between adult selected clones of Arbutus unedo L. and Pisolithus arhizus. Two micropropagated clones were tested: AL1, in vitro and C1 (acclimatized plants) in nursery and later in a field trial. In vitro, rooted shoots were transferred to test tubes containing the substrate previously inoculated with mycelium cultured on agar. In the nursery, two inoculation treatments wer...
Ploidy stability in embryogenic cultures and regenerated plantlets of tamarillo
Currais, Lara; Loureiro, J.; Santos, Conceição; Canhoto, J. M.Ploidy levels of short-term (1 and 2 years) and long-term (7 and 10 years) embryogenic cultures as well as of regenerated plantlets of tamarillo were analyzed by flow cytometry and chromosome counts. Embryogenic cultures were induced from expanding leaves cultured in the presence of Picloram or 2,4-dichlorophenoxyacetic acid (2,4-D) and monthly subcultured on the same media. Embryo development and plantlets wer...

Olive tree Galega cultivar acessions' identification based on RAPD markers
Figueiredo, E.; Canhoto, J.M.; Ribeiro, M.M.A.Olea europaea ssp. europaea (Oleaceae) grows in the Mediterranean region. The fruits are used for olive oil and for fruit canning, besides the species is drought and salt tolerant. The Galega cultivar represents 80% of the Portuguese olive area, and it is used in four out of the five Protected Origin Denomination (POD) regions. Despite the large distribution area in the country, cultivar certification is done t...
DNA markers to study genetic diversity and fingerprinting in Arbutus unedo L. (...
Gomes, F.; Costa, R.; Ribeiro, M.M.A.; Figueiredo, E.; Canhoto, J.M.Strawberry tree (Ericaceae) is a species of Mediterranean climates growing in several countries of the Mediterranean basin as well as in Portugal and Ireland. The edible fruits have been used in different ways yet the production of a popular spirit is still the main application. The species is also interesting from an ecological perspective since it is drought tolerant and fire resistant. In spite of its large ...
Effect and analysis of phenolic compounds during somatic embryogenesis inductio...
Reis, E.; Batista, M. T.; Canhoto, J. M.Summary. The effect of phenolic compounds on somatic embryogenesis in Feijoa sellowiana was analysed. The results showed that caffeic acid (140–560 µM) significantly increased somatic embryogenesis induction compared with the control. The presence of phloridzin, even at lower concentrations (11.5 µM), or caffeic acid or phloroglucinol at concentrations greater than 140.0 and 197.5 µM, respectively, inhibited s...
