Symbiont effectof rhizobiumbacteria and vesicular arbuscular mycorrhizal fungi onPisum sativumin recultivated mine spoils

Growth of different tree species and their nutrient uptake in limestone mine spoil as influenced by arbuscular mycorrhizal (AM)-fungi in Indian arid zone

“…The inoculation effect varied from one species to the other with the maximum response with A. indica while the minimum with A. eriopoda. Call & Mckell (1985) and Biro et al (1994) reported an improvement in the growth of many forage species including shrubs and trees in various mine spoils upon the introduction of arbuscular mycorrhizal fungi isolated from the degraded soils. Enhanced growth associated with AM-funal inoculation in hungry and thirsty soils and mine spoils has been attributed to the enhanced uptake of various nutrients especially phosphorus (Moser & Haselwandter, 1983), ability to withstand water stress through uptake and transport of water in plants, the ability of the plants to withstand high temperatures (Hayman, 1983), and the regulation of plant growth through production of growth-promoting substances (Allen et al, 1980).…”

Role of Beneficial Microsymbionts on the Plant Performance and Plant Fitness

“…In agricultural field conditions or in technogenous areas, like surface coal-mining sites, artificial development of symbiosis enhances the plant-growth and development (Biró et al 1993b(Biró et al , 2000a.…”

“…The success of these technologies is highly dependent on the effectively and infectivity of the indigenous microbes and on the interactions between the main participants, such as the mycorrhizal fungi in the rhizosphere (Lindermann 1983;Puppi et al 1994). Compatible combinations of the inoculated microbes, such as the symbiotic N 2 -fixing rhizobium bacteria and the AM fungi, may result, therefore, in an enhanced effect on the plant development (Biró et al 1993b;Paula et al 1992) in various legumes. Positive influence of the associative Azospirillum diazotrophs on the AM fungal activity is also reported (Garbaye 1994), especially on the monocotyledonous host plants.…”

“…The number of spores in the rhizosphere is highly variable in the multifactorial soil-plant systems (Landwehr et al 2002). Besides the type of higher plants and the vegetation period, the soil compaction (Biró et al 1993b), the water content (Zak and Parkinson 1982) and the soil acidity or cation exchange capacity (Ho 1987) influence the spore number in the rhizosphere.…”

Influence of Bioinoculants on Growth, Nutrient Uptake and Yield of Green Gram[Vigna radiata(L.) Wilczek]

“…It is well documented that plant-growth-promoting rhizosphere microorganisms like Pseudomonas, Trichoderma, Azospirillum and Rhizobium diazotrophs enhance arbuscular mycorrhizae (AM) fungal colonization and activity resulting in better plant performance (Subba Rao, 1985;Paula et al, 1992;Biro et al, 1993;Garbaye, 1994;Barea et al, 1998;Hazarika et al, 2000;Mar Vazquez et al, 2000;Tsimilli-Michael et al, 2000;Muthukumar et al, 2001;Rudresh et al, 2005). Similarly, biological control preserves environmental quality by reducing chemical inputs in future sustainable agricultural management practices (Altieri, 1994; Barea and Jeffries, 1995).…”
