Abstract

— The effects of an arbuscular mycorrhizal fungus (Glomus sp) on development and carbohydrate metabo- lism of micropropagated plantlets of a pear clonal rootstock (OH x F 51) were examined during the first vegetative growth and at the beginning of the second growing year. Plant growth was assessed in terms of stem height, leaf num- ber, root length, fresh and dry weight of the whole plant, stem, leaves and root mass at different times following inocu- lation. The levels of soluble (fructose, glucose, sucrose and sorbitol) and insoluble (starch) sugars were analyzed in stems, leaves and roots using gas-chromatographic techniques. Inoculation with Glomus sp was effective in promoting plant growth causing a strong increase in shoot height, root length and a greater growth rate of dry matter. Colonization of rootstock roots with Glomus sp altered the carbohydrate metabolism and partitioning within the plant. carbohydrate / pear rootstock / arbuscular mycorrhizae / micropropagation Rsum — Croissance et tat des glucides chez des microplantes de Pyrus communis L inocules avec Glomus sp. Les effets d'un champignon mycorhizogne arbuscule (Glomus sp) sur la croissance et sur le mtabo- lisme glucidique d'un porte-greffe micropropag de poirier (OH x F 51) ont t examins pendant les premiers stades et au dbut de la deuxime anne de dveloppement. La croissance des plantes a t value, diffrentes priodes aprs inoculation, par des mesures de hauteur de tige, de nombre de feuilles, de longueur de racines et de poids de matire frache et sche. Le contenu en glucides solubles (fructose, glucose, saccharose et sorbitol) et insolubles (amidon) a t mesur dans les tiges, les feuilles et les racines par chromatographie gazeuse. L'inoculation avec Glomus sp s'est rvle efficace pour stimuler la croissance des plantes en induisant une forte augmentation de la hauteur des tiges, de la longueur des racines et du taux de matire sche par rapport aux tmoins. La colonisation des racines de porte-greffes par Glomus sp a provoqu aussi un changement au niveau du mtabolisme des glucides et de leur rpartition dans la plante.
