Exploitation de la variabilité somaclonale pour la recherche d'oeillet (Dianthus caryophyllus L.) tolérant à la salinité
Abstract
Exploitation of Somaclonal Variability for Research of Carnation (Dianthus caryophyllus L.) Tolerant to Salinity. Callogenesis in carnation (Dianthus caryophyllus L. 'Légion d'Honneur') is possible from internodes in a medium containing 0.1 mg.l-1 NAA and 0.1 mg.l-1 TDZ. Regeneration from callus needs 2 mg.l-1 BA. Shoots rooting is obtained on a medium containing 0.5 mg.l-1 IBA. Callus growth is reduced and regeneration rate is very affected in presence of NaCl 100 mM. Shoot rooting is better without NaCl. Regenerated plants present somaclonal variation and those obtained under salt stress have a better relative tolerance to salinity than plants regenerated without salt.
