Rhizobial Inoculation

A field experiment was conducted with 8 genotypes of vegetable pea and 3 levels of rhizobial inoculation for two consecutive years. Inoculation with Rhizobium leguminosarum @ 20 g kg −1 seed made the plants taller and enhanced biomass production through branching, but delayed maturity. It resulted in more pods, enlarging them to contain more seeds, leading to higher test weight and enhanced harvest index. It increased nodulation, the benefit of which was reflected in most of the yield traits. It also enriched the seeds with nitrogen and protein, as well as activating nitrogenase enzyme in the root nodules to fix more atmospheric nitrogen.

Negative Effect

Study on the effect of three heavy metals (Al, Fe, Mo) were studied on two strains of rhizobia isolated from root nodules of two tropical legume species, Mucuna pruriens and Trigonella foenumgraecum. The effects were assessed for bacterial growth in culture and in symbiotic parameters such as biomass production and nodulation in host plant. Aluminium was found to have detrimental effect in both in-vitro and in-vivo condition in all its concentration. Iron was found to support bacterial growth and symbiotic parameters such as biomass production and nodulation up to 25 μM. Above 25 μM iron was found to have negative effect. Molybdenum was beneficial up to the 75 ìM concentration in culture of both strains of bacteria while in plant productivity and nodulation it was beneficial only up to 20 μM.

Thin Plastic

A low level of sporulation was seen to occur consistently within root nodules produced by inoculation with specific pure cultured strains of Frankia. The three Frankia strains, UFGCeI5 from Casuarina equisetifolia, UFGCgI1 from Casuarina glauca, and UFGMuI1 from Myrica pubescens, infect and produce root nodules on a range of actinorhizal host plants. Sporulation was detected in nodules of each host plant examined when the Frankia used for inoculation was one of these three strains. The amount of sporulation that occurred in any particular nodule was so low that it required identification in thin plastic sections prepared for examination at high magnification at the light microscope level. These strains, unlike other isolates studied, appear to be genetically predisposed to sporulate in the host root nodules. All three strains also show spontaneous spore release in culture. Key words: actinorhizal plants, endosymbiont, Frankia, sporulation.
