Abstract
— Micropropagated plantlets of strawberry (Fragaria x ananassa Duch Senga Sengana) were inoculated at the beginning of the weaning stage with a Glomus mosseae strain from Rothamsted Experimental Station (UK) or with 8 Finnish Glomus isolates, including 1 G mosseae isolate, 4 G intraradix isolates and 3 isolates of an unidentified Glo- mus species. After 8 wk (July 1990), inoculated plants were planted in the field: the most efficient fungi, ie G mosseae Rothamsted, Glomus sp V 3 and Glomus sp V 4 , increased shoot growth several-fold during the weaning stage. Growth responses persisted throughout the 1st yr in the field, and partly throughout the 2nd yr. Root colonization by different fungi was from near 0-60% during the weaning stage. In the 2nd yr, after overwintering, root colonization of inoculat- ed plants ranged from 8-35% as compared to 4% for the control plants. The need for more precise studies of the in- fluence of winter on the biological efficiency of introduced VAM fungi to strawberry roots is discussed. strawberry / arbuscular mycorrhizal fungi / microplant weaning stage Rsum — Inoculation de mycorhizes arbusculaires des fraisiers micropropags et observation en champ en Finlande. Des plantes de fraisier (Fragaria + ananassae Duch, Senga Sengana) ont t inocules au dbut du sevrage avec une souche de Glomus mosseae provenant de Rothamsted Experiment Station, ou avec 1 des 8 isolats finnois de Glomus dont 1 de G mosseae 4 de G intraradix et 3 isolats d'une espce non identifie de Glomus. Aprs 8 semaines, en juillet 1990, les plantes inocules ont t plantes au champ. Les champignons les plus efficaces, c'est--dire G mos- seae Rothamsted, G sp, V 3 et G sp V 4 ont multipli la croissance des tiges de plusieurs fois pendant la priode de se- vrage. La rponse de croissance persista pendant toute la premire anne au champ, et partiellement pendant la deuxime anne. La colonisation des racines par les diffrents champignons a t de presque 0 60% pendant le se- vrage. La deuxime anne, aprs passage de l'hiver, la colonisation variait de 8 35%, contre 4% pour les tmoins. Le besoin d'tudes plus prcises sur l'influence de l'hiver sur l'efficacit biologique des VAM introduites dans les racines de fraisier est discut. fraisier / champignon m ycorhizien arbusculaire / microplant / sevrage
