The effect of different sources of arbuscular mycorrhizal (AM) fungi on chilli seedlings was conducted in the net house of Soil Science Division, BARI, Gazipur. The AM fungi from various sources including an exotic variety were included in this study. Soil-based AM inoculum was used at the rate of 50 g/pot. It was found that the growth, biomass yield and nutrient uptake of inoculated seedlings were significantly higher than those of uninoculated seedlings. Such higher growth and nutrient uptake appeared to be due to beneficial effects of AM fungi. The performance of the indigenous AM inocula was much better than the exotic inoculum with respect to biomass production and nutrient uptake. Inoculation with AM fungi helped to produce healthy and vigorous seedlings with faster growth. This would help reducing the nursery life and thereby reduce the cost of seedling production. It is expected that the AM inoculated seedlings might perform better in the field trail since the fungi could colonize with the roots.Keywords: Arbuscular mycorrhiza, Chilli seedlings, Pot cultureDOI: http://dx.doi.org/10.3329/bjm.v23i2.870 Bangladesh J Microbiol, Volume 23, Number 2, December 2006, pp 98-101

An experiment on the effect of different sources of Arbuscular mycorrhiza (AM) fungi on tomato seedlings (var. Roma VF) was conducted at the Bangladesh Agricultural Research Institute, Gazipur during rabi 2007-08 and 2008-09. Eight sources of AM fungi viz., AM-01 (Jessore), AM-02 (Rahmatpur), AM-03 (Joydebpur), AM-04 (Ullapara), AM-05 (Jamalpur), AM-06 (Hathazari), AM-07 (Ishurdi), and AM-08 (Rajshahi) were studied along with a control and mixed sources on tomato seedlings. Soil based AM inoculum at the rate of 2.0 kg/m2 was used. Biomass yield of tomato (Roma VF) increased from 14.8% to 53.6% in 2007-08 and 32.1% to 58.4% in 2008-09 over control by inoculation with different sources of AM. The highest biomass yield (301 mg/seedling) of tomato (Roma VF) was observed with AM-05 (Jamalpur source), which was higher to all AM sources except AM-07 (Ishurdi source). Nutrient uptake by tomato seedlings was improved by inoculation with AM fungi. The AM fungi from all the sources appeared to be effective in enhancing the growth and development of tomato seedlings.

The diversity of arbuscular mycorrhizal (AM) fungi of <I>Acacia catechu</I> Willd. was studied. Dominant AM spores, the bacterium <I>Rhizobium</I> sp. along with the fungus <I>Trichoderma viride</I> were isolated from the rhizosphere of <I>A. catechu</I> and mass-produced in laboratory. The co-inoculation effect of <I>Glomus mosseae, Glomus fasciculatum</I>, mixed AM (<I>Glomus</I> spp. [except <I>G. mosseae, G. fasciculatum</I>] with <I>Acaulospora</I> spp., <I>Sclerocystis</I> spp. and <I>Gigaspora</I> spp.), <I>Rhizobium</I> sp. and <I>Trichoderma viride</I> was studied as exerted on the growth of <I>A. catechu</I> seedlings. All inoculated seedlings showed improved seedling growth compared to the control. Inoculated seedlings had a pronounced effect on all growth parameters such as height, fresh and dry weight of roots and shoots, AM spore count, per cent mycorrhizal colonization in roots and root nodule number in comparison with uninoculated seedlings. Phosphorus uptake was also higher in inoculated seedlings than in the control. This study provides a good scope for commercially utilizing the efficient strains of AM fungi for beneficial effects with other beneficial rhizosphere microflora in the primary establishment of slow growing seedlings ensuring better survival and improved growth.

AbstractTo overcome phosphorus (P) deficiency, about 80% of plant species establish symbiosis with arbuscular mycorrhizal fungi (AMF), which in return constitute a major sink of photosynthates. Information on whether plant carbon (C) allocation towards AMF increases with declining availability of the P source is limited. We offered orthophosphate (OP), apatite (AP), or phytic acid (PA) as the only P source available to arbuscular mycorrhiza (AM) (Solanum lycopersicum x Rhizophagus irregularis) in a mesocosm experiment, where the fungi had exclusive access to each P source. After exposure, we determined P contents in the plant, related these to the overall C budget of the system, including the organic C (OC) contents, the respired CO2, the phospholipid fatty acid (PLFA) 16:1ω5c (extraradical mycelium), and the neutral fatty acid (NLFA) 16:1ω5c (energy storage) at the fungal compartment. Arbuscular mycorrhizal (AM) plants incorporated P derived from the three P sources through the mycorrhizal pathway, but did this with differing C-P trading costs. The mobilization of PA and AP by the AM plant entailed larger mycelium infrastructure and significantly larger respiratory losses of CO2, in comparison with the utilization of the readily soluble OP. Our study thus suggests that AM plants invest larger C amounts into their fungal partners at lower P availability. This larger C flux to the AM fungi might also lead to larger soil organic C contents, in the course of forming larger AM biomass under P-limiting conditions.

A field trial on alley-cropping was conducted at the University of Ibadan research farm in the 1990/91 cropping season to assess the contributions of arbuscular mycorrhizal (AM) fungi and hedgerow woody legumes to the yield and nutrient uptake of cassava (Manihot esculenta Crantz) as an intercrop in an infertile soil. The trial also investigated the influence of AM fungi on the interplanting of a non-nodulating woody legume Senna siamea (syn. Cassia siamea) with a nodulating woody legume (Leucaena leucocephala).AM contributions to cassava were greater than the hedgerow contributions, which demonstrated that AM associations are an essential component in the nutrition of cassava. In contrast to cassava, AM inoculation only influenced the leaf dry weight and uptake of nutrients of non-interplanted woody legumes but not the above-ground biomass and P uptake of interplanted woody legumes. However, non-inoculated interplanted Leucaena benefited more from indigenous AM fungi than the competing Senna. The negative contributions to the nutrient uptake (K, Ca and Mg) of cassava by hedgerows and the lack of response to AM inoculation in interplanted hedgerow woody legumes could be attributed to root competition among the different plant species growing in close proximity to each other. The present results show that cassava benefits more from AM association than Leucaena which in turn benefits more than Senna in an alley-cropping system.

The Impact

Background: Salinity stress remains a chronic threat to pulses productivity in India. Arbuscular mycorrhizal (AM) fungi play a major role which influences plant growth, nutrient uptake and contributes to ecosystem processes under salt stress. The present study aims, to demonstrate the impact of Glomus mosseae (Gm), on physio-biochemical attributes of mungbean exposed to salinity. Methods: Two highly tolerant, two moderately susceptible and two highly susceptible mungbean lines were subjected to salinity stress alone and in presence of Gm under greenhouse. Result: Results revealed that Gm alleviates the salinity stress related alterations by improving the nutrient uptake and by balancing the ratio between K:Na, which impact directly the osmoregulation of the plants. Mycorrhiza inoculation also increased the proline content (23%), water-use efficiency (38%) and activity of different antioxidant enzymes in a significant manner providing efficient protection against salinity stress. All these positive impacts of Gm were duly reflected in a significant increase in grain yield (more than 2 fold increase) in mungbean. Interestingly, salt-induced retarded growth and decline in other biochemical parameters in susceptible lines recorded remarkable recovery following Gm inoculation.

Bedding Plant

Herbaceous plants used in island beds and borders need to be rapid growing, high performing and maintaining good visual quality during the growing season. Arbuscular mycorrhizal (AM) fungi application is acquiring interest for its beneficial effects on ornamental bedding plants. Gazania rigens is a herbaceous ornamental plant grown for its large daisy-like flowers. The species thrives in the coastal areas of the Mediterranean region, particularly in the mild climate of southern Italy and Sicily, where performs well in summer bedding schemes in sea side gardens even in dry and windy conditions. The aim of this study was to evaluate the effect of inoculation with Rhizophagus irregularis on several ornamental parameters of Gazania rigens. Prior to transplanting, three-months-old plants received a mycorrhizal inoculum carrying 40 spores g-1 of Rhizophagus irregularis. Inoculum was applied at a rate of 10 g plant-1. The AM application significantly increased number of flowers per clump by 100% and number of flowers per plant by 124.0%. Rhizophagus irregularis also positively influenced number of leaves per plant, plant height, and roots dry weight. Our findings indicated that mycorrhizal inoculation with R. irregularis may be beneficial to nursery growers wishing to produce high quality gazania for spring-summer bedding plant schemes.

An experiment on the effect of rate of Arbuscular mycorrhiza (AM) inoculum on tomato seedlings was conducted at Bangladesh Agricultural Research Institute, Joydebpur, Gazipur, Bangladesh for two consecutive years. Seven rates of AM inoculum viz., 0, 0.5, 1.0, 1.5, 2.0, 2.5, and 3.0 kg/m2 were tested. Cowdung was used at a rate of 5 kg/m2. Seeds were sown in 10 cm apart lines on 13 November 2007 and 11 November 2008, and the seedlings were thinned out to about 3 cm from seedling to seedling within a week of germination. Roma VF was used as a variety of tomato. Biomass yield, root colonization, spore number, and nutrient uptake by tomato seedlings increased remarkably with the rates of AM inoculum. The biomass yield followed a quadratic trend with the increase of AM inoculum rate from 0 to 2.0 kg/m2 in 2007-08 and 0 to 1.5 kg/m2 in 2008-09.

The current study, performed in Castilla-La Mancha (Spain) in 2003–04, reports the growth, nutrition, tolerance to transplanting stress, and resistance to Verticillium dahliae of olive plantlets (Olea europaea L.) inoculated with different arbuscular mycorrhizal (AM) fungi (Glomus mosseae, G. intraradices and G. claroideum). Inoculated plants tolerated the stress of transplanting better than non-inoculated plants. Compared with controls, plantlets inoculated with any of these three Glomus species grew taller, had more and longer shoots, and showed higher plant N, P and K concentrations. However, colonization seemed to have no influence on resistance to V. dahliae.
