Abstract

L'enracinement sous brouillard d'extrémités de tiges prélevées sur des plantes en pots après le traitement thermique se révèle souvent décevant (20 à 25%). Ces extrémités, mises stérilement en culture sur milieu nutritif gélosé, ne sont que rarement contaminées par des champignons ou des bactéries (moins de 3%), et l'on obtient ainsi un nombre élevé de plantes établies au champ à partir des extrémités implantées (82%).

lmprovement of the shoot-tip yield of heat treated pot plants using culture on agar nutrient medium under sterile conditions

Rooting shoot-tips from heat treated pot plants under mist proved very unsuccessfull (20 to 25%). Use of culture on agar nutrient medium under sterile conditions with these shoot tips resulted in a surprisingly low fungal and bacterial contamination rate (less than 3°/o) and a very high proportion of successfull establishment of plants in the field from the shoot-tip inplants (82%).
