Resumé

Les auteurs proposent une méthode d'utilisation du15N2 pour l'étude de la fixation d'azote dans les associations complexes légumineuses-Rhizobium cultivées sur sol. La procédure consiste, à marquer l'atmosphère du sol à l'aide de15N2 et à calculer la quantité d'azote total fixé pendant cette période. Les premiers résultats obtenus sur des haricots et des trèfles démontrent qu'après seulement 7 h d'incubation, des quantités significatives de15N sont mesurées dans les plantes permettant ainsi de déterminer précisément la valeur du rapport C2H4/N2 qui a été établi entre 2,6 et 3,1 dans les conditions de l'expérience. Sur de longues périodes, ces mêmes quantités se sont avérées suffisantes pour suivre la dynamique de l'azote des nodules vers les organes reproducteurs de plants de haricots.

Summary

A method for use of15N2 in the study of dinitrogen fixation by complex legumes-Rhizobium associations grown on soil is proposed. The procedure consists in labelling the soil atmosphere with15N2 during short periods of time, measuring15N enrichment in the plants and calculating the total nitrogen fixed during this period. The first results obtained with bean and clover plants demonstrate that after only 7 h of incubation, significative amounts of15N are measured in the plants to allow precise determination of C2H4/N2 ratio which ranged between 2.6 and 3.1 in this experiment. Over longer periods of time, such amounts are meaningfull to follow the pattern of N dynamic from the nodules to the reproductive organs of bean plants.
