“…Caravacaet al (2002) reported a significant improvement in growth of P. lentiscus seedlings due to infection with AMF in a ensuring success while slow release fertilisers can also be used, they however can be expensive for large scale planting of qegraded arid lands by governments and local farmers with limited funds. The higher AMF in the poor growing group is in contrast with other studies which have found an improved plant growth for AMF forming seedlings (Jones et al, 1991;Rao and Tak, 2001;Tarafdar and Kumer, 1996). Inoculation with AMF fungi has sometimes depressed plant growth, particularly where the phosphorus supply does not limit the growth of non-mycorrhizal plants (Azcon et al, 2003 ).…”

SYNOPSISThe effect of the level of arbuscular mycorrhizal fungi (AMF) colonisation on the growth of Pterocarpus angolensis was studied. Mycorrhizal infected seedlings, showing either good or poor growth, under the same environmental conditions (temperature, humidity, light level) were analyzed for above and below ground biomass and Nand P concentration. The grouping was based on the number ofleaves and seedling size. All plants had AMF infection, with poor growth plants having a 7 5% infection and good growth plants 45%. The highly infected poor growth plants had fewer leaves, smaller total leaf area and total plant mass. The below ground plant component Nand P concentration of good growth plants was higher than in poor growth plants. There was however no difference inN and P concentrations of above ground components between the two groups. No nodules were recorded for good growth plants while plants in the poor growth group had nodules. There was no difference in the specific leaf mass and shoot:root ratio of the two groups, although the leaf area ratio was higher in good growth plants. The high AMF infection had a negative effect on the growth and development of plants. This study highlighted the presence of AMF in nursery grown Pterocarpus angolensis and the host benefits from various colonisation levels. A long-term field trial is needed to study the effects ofdifferentAMF colonization levels on tree vigour under different environmental conditions.

“…These results indicate the importance of selecting strains for forestry production since indigenous microbes are more suitable for this (Rao and Tak 2001). However, many practical problems such as time of inoculation and the AM species colonizing C. tomentosum roots need to be investigated.…”

Centrolobium tomentosum is a tropical legume tree indicated for functional and structural restoration of riparian areas. This study was conducted to characterize the rhizobia isolated from nodules of C. tomentosum in situ and to determine their capacity of renodulation, in an experimental area of land rehabilitation in the Rio Doce valley. Nodulation potential to inoculation with 2 selected fast-growing Rhizobium strains separately and a mixed inoculum of arbuscular mycorrhizal fungi was evaluated by the use of antibiotics resistance. Flood disturbance were observed not to affect renodulation by fast-growing strains. DNA fingerprinting RAPD (random amplified polymorphic DNA) and lipopolysaccharides (LPS) profiles were used to examine molecular relationships among field isolates, inoculants and reference strains. Maximal renodulation was exhibited by strain BHCBAb1 after 24 months after transplantation. Centrolobium tomentosum forms symbiosis with fast-and slow-growing Rhizobium strains, and it is suggested that their nursery culture could be improved by inoculation of selected strain under low nitrogen-input conditions.

“…Thus, the enhancement of soil enzyme activities is one of the physiological and biochemical mechanisms involved in a mycorrhization effect on plant mineral nutrition. Rao and Tak (2001) found that mycorrhizal fungal inoculation resulted in enhanced plant growth, total uptake of N, P and many other nutrients, activities of dehydrogenase, phosphatase and nitrogenase in the rhizosphere in gypsum mine spoil. Owing to the energy and cost-intensive manufacture of chemical fertilizers, use of microbial inoculants to supplement a part of phosphorus requirement has attained immense importance (Bagyaraj et al, 2015).…”

A field experiment was conducted to evaluate the response of AMF species with different phosphorus (P) levels for root colonization, microbial population under maize in an alluvial soil. Of all the species of mycorrhizae taken under consideration, G. mosseae along with 75% RDF of P was found to perform better in terms of root colonization, number of spores and grain yield. Application of G. mosseae @ 10 kg ha-1 + 50% P + 100% NK produced significantly higher root colonization by 177.32, 55.20, 37.75 and 101.95 per cent over the treatments 100% RDF, G. mosseae @ 10 kg ha-1 + 75% P + 100% NK, G. coronatum @ 10 kg ha-1 + 75% P + 100% NK, G. decipien @ 10 kg ha-1 + 75% P + 100% NK and control, respectively. The similar trend was observed for number of spore count. The maximum number of bacteria (40Ã—10-5 cfu g-1 soil) was found with the inoculation of G. mosseae @ 10 kg ha-1 + 75% P + 100% NK at flowering stage. The maximum grain yield (7656.61 kg ha-1) was recorded with the application of G. mosseae @ 10 kg ha-1 + 75% P + 100% NK, which was 111.92 per cent significantly higher the control treatment. G. mosseae along with 75% RDF of phosphorus inoculation proved to be effective in modifying the soil microbe population and community structure and also in enhancing the grain yield.
