Resumo
Sideritis leucantha Cav. subsp. leucantha es un endemismo valenciano con uso medicinal que tiene diversos problemas de conservación. Por tanto, el objetivo principal de este trabajo fue probar el efecto de un tratamiento de precultivo para la posterior criopreservación de brotes apicales de esta especie. Los resultados mostraron que el precultivo con sacarosa 0.3 M durante 24 horas result en una mayor supervivencia de los explantes y regeneración in vitro después de tres tratamientos de vitrificación ensayados. Estos resultados sugieren que el acondicionamiento de los explantes puede mejorar la supervivencia de los explantes de S. leucantha subps. leucantha cultivados in vitro tras la criopreservación
