    Notes: Summary Field and cylinder experiments conducted in France and in Senegal showed that polyacrylamide, previously proposed as an entrapping gel for preparing Rhizobium inoculants, could be replaced by alginate (AER inoculant) or a mixture of xanthan and carob gum (XER inoculant). Semi-dried or dried AER and XER were used successfully provided that their storage time was less than 90 days. In soil inoculation trails, no marked differences were observed among semi-dried XER, dried AER, and dried XER. A number of seed inoculation experiments indicated that dried XER significantly outranked AER. Seeds preinoculated by up to 48 days with XER yielded plants which were comparable in nodulation and growth parameters to those derived from plant receiving peat inoculation at the time of planting.

    Notes: Summary Alders have an important role to play in biomass producing stands because of their N2-fixing ability and their capacity to withstand soils having an excess of moisture. The objectives of preliminary trials were (1) to find if there is any alder-genotype xFrankia-strain interaction when the effect of inoculating the bacteria was compared to no inoculation in seed beds of different species and provenances of alder, (2) to measure the possible effect of black alders interplanted in poplars compared to pure poplar plots. Two trials were laid out to study the alder-Frankia interaction. Both produced interaction. In the first one the inoculation had a favorable effect onAlnus glutinosa at age 2 years andA. cordata at age 1 and 2 and no effect onA. rubra. In the second one the inoculation had a depressive effect at age 1 on 2 of 3 provenances ofA. rubra and no effect on 1A. rubra, 3A.glutinosa and 3A. cordata provenances. A closely spaced field trial associating one black alder provenance and the poplar clone UNAL gives no superiority of mixed plots compared to pure plots. The results suggest that the N2-fixation of alders is not profitable to poplars at age 3 with a 1.5×2 m spacing.
