Abstract

The application of beneficial microorganisms can enhance the growth of crops and increase their yields. In this context, we analysed the growth and development responses of six legume species inoculated by the mycorrhiza-based bio-fertilizer "Stanes Symbion VAM Plus" in greenhouse conditions. The effect of inoculation by Symbion VAM on legumes growth and development depends on the species and the cultivar used. A significant increase of shoot fresh weight, number of nodules and root dry weight was observed in common bean, pea and alfalfa, respectively. The most positive effect of inoculation was observed with the A17 Medicago truncatula line, which showed an increase in shoot and root dry weights, in nodule and pod numbers, and an early blooming. However, chickpea and lentil inoculated plants didn't show any increase for all measured growth and development traits. This positive effect of inoculation on A17 line by the Symbion VAM biofertilizer was associated with important mycorrhiza root colonization (21 to 40%) in comparison to the other legume cultivars at 50 days post inoculation. This study suggests that the success of inoculation with mycorrhiza-based inoculants depends on several factors including the density of inoculants in infective propagules and the length of legume life cycle.

8 of 13 groups shown: named compounds and organisms first, then groups whose results differ (checked claim by claim), then those with positive and negative results, then the smaller groups.

Claims are grouped by organism, treatment and what was measured or targeted. A paper counts as positive when any of its claims in the group is positive.
