Abstract
Rhizobium of some cultivated and spontaneous forage legumes (alfalfa,Vesce et trèfle) in fact the objective:
-A physiological characterization (growth rate, shape, color and size of colonies) and morphological (form of bacteria) on the other hand their impact on the behavior of their host species: By carrying out some tests affecting the biochemical aspect (content of soluble sugars and proteins) in vegetative and structural parts (shape and structure of nodules).
- The results show that:
• All bacteria manifest rapidly on the culture medium
• White and spherical colonies vary in size
• Bacteria are all Gram-negative, bulky bacilli in R.biovar trifolii.
The effectiveness of bacterioids on the primary metabolism of host plants, by the elevation of proteins and the good translocation of sugars in vegetative parts with a particular trophic requirement especially for phosphorus in S.meliloti
Cylindrical or branched nodules have an infected central cortex and a peripheral region containing leghemoglobin.
Keywords: Legumes; Symbiotic bacteria; Plant biotechnology; Rhizobium; Forage plants, plant breeding.
