In vitro rooting of micropropagated shoots from juvenile and mature Pinus pinaster explants : influence of activated charcoal

Dumas Elisabeth, Monteuuis Olivier. 1995. In vitro rooting of micropropagated shoots from juvenile and mature Pinus pinaster explants : influence of activated charcoal. Plant Cell, Tissue and Organ Culture, 40 : 231-235.

Résumé : The ability for adventitious rooting of micropropagated shoots from juvenile and mature #Pinus pinaster# Ait. explants was assessed in vitro on a rooting expression medium. The different rooting traits observed, namely the rooting rate, the number and the length of the adventitious roots, and the root score, were greatly influenced by the age of the donor plant : 98% of juvenile explants rooted, while only 49% of mature explants did. Addition of activated charcoal in the rooting expression medium improved the overall rooting capacity of the mature explants to an average of 78%. whatever the plant material, the number and the length of the adventitious roots, as well as the root score, fluctuated according to the sampling date.
