TLDR
The physiological responses of the plant roots to inoculation with Azospirillum are discussed, and field and greenhouse experiments carried out with these bacteria during 1994-2001 in Belgium, Uruguay, Mexico and Israel are reported on.Abstract:
Azospirilla are free-living rhizobacteria that are able to promote plant growth and increase yields in many crops of agronomic importance. It is assumed that the bacteria affect plant growth mainly by the production of plant growth promoting substances, which leads to an improvement in root development and an increase in the rate of water and mineral uptake. In the present review, we discuss the physiological responses of the plant roots to inoculation with Azospirillum, and report on field and greenhouse experiments carried out with these bacteria during 1994-2001 in Belgium, Uruguay, Mexico and Israel.read more
