Octoploid genotypes of Asparagus officinalis L. cv. ‘Morado de Huetor’, a tetraploid Spanish landrace, were successfully induced by treating in vitro rhizome buds explants with colchicine. Pulses during 24 h with different concentrations of colchicine are able to induce polyploid plants, colchicine applied at 0.1 % induce a 7 % of octoploid genotypes with a(More)
Periodic composites such as acoustic metamaterials use local resonance phenomenon in designing low frequency sub-Bragg bandgaps. These bandgaps emerge from a resonant scattering interaction between a propagating wave and periodically arranged resonators. This paper develops a receptance coupling technique to combine the dynamics of the resonator with the(More)
