Different combinations of auxins and cytokinins were employed to assess the regeneration capacity from in vitro leaf explants of Lonicera nitida Wils. cv ‘Maïgrün’. A high frequency of rhizogenesis was noticed, with 2.3 μM thidiazuron plus 2.9 μM indole-3-acetic acid as the only hormonal combination to support caulogenic responses. Increasing thidiazuron(More)
The ploidy level variations of protoplast cultures ofNicotiana plumbaginifolla Viviani (n=10) were investigated from protoplast isolation until regenerated buds, using cytophotometric measurements of nuclear DNA content and chromosome counting. An increase in the average nuclear DNA amount has been found to occur in freshly isolated protoplasts after 15(More)
BACKGROUND AND AIMS Aster pyrenaeus (Asteraceae) is an endangered species, endemic to the Pyrenees and Cantabrian Mountain ranges (Spain). For its long-term persistence, this taxon needs an appropriate conservation strategy to be implemented. In this context, we studied the genetic structure over the entire geographical range of the species and then(More)
