Positive Effect

The study aims to evaluate the effect of endomycorrhizal inoculum (arbuscular mycorrhizal fungi), phospho-compost and phosphate sludge in single (M, PC, PS) or dual combinations (PC+M, PS+M, PS+PC) compared to agricultural and Mamora soils (A and S) on the growth, flowering, and yield of tomato plants. Among the studied treatments, the substrates containing 5% of phospho-compost combined with endomycorrhizal inoculum (PC+M) gave the most positive effect followed by phospho-compost (PC) and endomycorrhizal inoculum (M). In response to PC+M substrate, tomato plant height, the number of leaves and flowers attained 90 cm, 30, and 25, respectively. In substrates PC and M, tomato plants showed a height of 85 and 75 cm, leaves number of 30 and 19 leave/plant and number of flowers of 21, and 19 flower/plant. An optimal yield with (12 fruits/plant) was recorded in tomato plants grown on the substrate amended with bio-inoculant (AMF) and phospho-compost at a rate of 5%. In terms of qualitative parameters, the highest fresh and dry weight of aerial plant parts and root system were recorded in tomato plants grown in culture substrate incorporating 10 g of endomycorrhizal inoculum and 5% of phospho-compost reaching respectively103.4 g, 34 g 90.1 g, 28.9 g as compared to 87, 51, 23 and 24.1 g noted by tomato plants on the substrate with phospho-compost (5%) (PC). The highest mycorrhization parameters (frequency (F), intensity of mycorrhization (M), average arbuscular content (A), average vesicular content (V), average intraradicular spore content (S)) were found in the roots of tomato plants growing on substrates amended with 5% phospho-compost plus 10 g of endomycorrhizal inoculum, with percentages of 100% F, 61% M, 40.67% A, 18.36% V, and 56.9% S.

Pure and biculture stands of rye `Wheeler' (Secale cereale L.) and field pea (Pisum sativum L.) were established and killed for mulch in Spring 1996, 1997, and 1998, in Columbus, Ohio. Treatments were five rye to pea proportions, each with a high, medium, and low seeding rate. Their effects on tomato (Lycopersicon esculentum Mill.) growth and yield were compared with those of a weedy check; a tilled, nonweeded check; and a tilled, hand-weeded check. Tomato tissue and soil were sampled for nutrient analysis. Number of leaves, branching, height, leaf area, dry weight, rate of flowering and fruit set, and fruit yield of tomato plants varied directly with the proportion of pea in the cover crop and decreased with reduced cover crop seeding rates. In 1997, yields of tomato were as high as 50 MT·ha-1 in the 1 rye: 3 pea cover crop; yield was poorest in the weedy check (0.02 MT·ha-1 in 1996). Most of the cover-cropped plots produced better yields than did the conventionally weeded check. No consistent relationship between levels of macronutrients in tomato leaf and soil samples and the cover crop treatments was established. Spring-sown rye + pea bicultures (with a higher ratio of pea) have a potential for use in tomato production.

Positive Effect

No clear data are available on how flavonoids from different chemical groups affect root colonization by arbuscular mycorrhizal fungi (AMF) and whether flavonoids affecting the presymbiotic growth of AMF also affect root colonization by AMF. In the present work, we compared the effect of flavones (chrysin and luteolin) and flavonols (kaempferol, morin, isorhamnetin, and rutin) on root colonization (number of entry points and degree of root colonization) of tomato plants ( Lycopersicum esculentum L.) with the effect of these flavonoids on the presymbiotic growth of these AMF, which has been reported in a recent study. With all tested AMF ( Gigaspora rosea , Gigaspora margarita , Glomus mosseae, and Glomus intraradices) a correlation between the number of entry points and the percentage of root colonization was found. When the number of entry points was high, root colonization was also enhanced. Application of the flavones chrysin and luteolin and of the flavonol morin increased the number of entry points and the degree of colonization,whereas the flavonols kaempferol, isorhamnetin, and rutin showed no effect. These results show that in contrast to their effect on the presymbiotic growth of the AMF on the level of root colonization, the tested flavonoids do not exhibit a genus- and species-specificity. Moreover, comparison of our data with the data obtained by J.M. Scervino, M.A. Ponce, R. Erra-Bassells, H. Vierheilig, J.A. Ocampo, and A. Godeas. (2005a. J. Plant Interact. 15: 22–30) indicates that a positive effect on the hyphal growth of AMF does not necessarily result in an enhanced AM root colonization, further indicating that the mode of action of flavonoids at the level of root colonization is more complex.

<p>Ginger (<em>Zingiber officinale</em>) is one kind of plants to be processed as traditional medicine, drinks, and spices. the smallest type of ginger that has many benefits as medical plant. Demand for ginger plants growing in the community is increasing. Additions of manure and arbuscular mychorrhizal fungi (AMF) can increase the quality and quantity of ginger. This was conducted to obtain the kinds of manure and levels of AMF to ginger to produce optimum growth and yield. This research used a completely randomized design (CRD) consisting of two treatment factors, namely planting medium and arbuscular mycorrhizal fungi (AMF). Results were analyzed by analysis of variance and if there is a real difference continued DMRT 5% level. The results showed that the differences in the kinds of manure and the levels of AMF increase growth and yield of ginger. Chicken manure application showed the highest results in the fresh weight of stover plant, dry weight of plant stover, fresh weight of plant rhizomes, and dry weight of the rhizomes. Whereas the additions of AMF 15 grams per plant in zeolite showed the highest results in the number of plant tillers, dry weight of plant stover, fresh weight of plant rhizomes, and dry weight of the rhizomes.</p>

We aimed to test the hypothesis that treatment with an aboveground plant conditioner has an effect on important vegetable crops inoculated with arbuscular mycorrhizal fungi (AMF) and on their colonization by AMF. Potting experiments were set with pepper and tomato plants inoculated with commercial AMF inoculum and plants were treated with an aboveground plant conditioner. After harvesting, the dry weight of shoots and roots were measured, and the AMF colonization of the roots was quantified. We found a significant effect of the treatment on fungal colonization: the AMF colonization, the hyphal colonization rate and the frequency of the arbuscules in the roots of both vegetables were lower when aboveground plant conditioner was applied. Although the two species differed, no significant effect of the treatment on the growth of the plants was detected. Based on our findings we assumed that the lower AMF colonization more greatly influenced the growth of the pepper cultivar studied. We demonstrated that treatment with a commercial aboveground plant conditioner had an antagonistic effect on AMF colonization, which, in addition to many other effects, might influence the growth vegetable crops. The interaction of different practices applied simultaneously should be tested to effectively help the development suitable agriculture systems.

Thyme (Thymus vulgaris L.) is one of the most important medicinal plants used in various pharmaceutical, osmotic, health, and food industries. Arbuscular mycorrhizal fungi (AMF) symbiosis is viewed as one of the several methods to improve growth under heavy metals stress. To investigate the effects of cadmium (Cd) and AMF bio-fertilizers on the growth and morpho-physiological characteristics of thyme, a greenhouse experiment was performed in three replications. Experimental treatments included Cd at three levels 0, 75, and 150 mg/kg of soil and AMF at three levels without inoculation, inoculation with Funneliformis etunicatum, and Funneliformis mosseae. Cadmium stressed plant showed reduced plant height, number of leaves, stem fresh and dry weight, and root fresh and dry weight while AMF inoculation enhanced the increased means of these traits considerably. Inoculation with F. mosseae also ameliorated the Cd stress (150 mg/kg) induced reduction in plant height, number of leaves, and stem and root dry weight by 13.41%, 8.42%, 30.3%, and 22.2%, respectively. Cadmium stress reduced membrane stability index while AMF inoculation enhanced membrane stability index considerably. An increase in soluble carbohydrate and proline content was observed due to Cd stress and AMF inoculation caused a further increase in these two metabolite contents ensuring better growth under Cd stressed conditions. Results indicated that F. mosseae had a higher efficiency in increasing morphological traits and improving physiological characteristics than F. etunicatum. Overall, AMF inoculation, especially F. mosseae significant ameliorative potential for Cd toxicity in thyme plants.

The present experiment was conducted at University of Pune for biocontrol of soil-borne plant pathogen Sclerotium rolfsii by incorporating arbuscular mycorrhizal fungi (Glomus fasciculatum) and conventional system of cultivation with different spacing pattern (15 and 30 cm) in field. Both mycorrhizal inoculation and 30 cm spacing pattern significantly increased growth and yield as compared to control or 15 cm spacing pattern. The pathogenic mycorrhizal groundnut plants in 30 as well as 15 cm spacing pattern showed better growth in terms of plant height, leaf and pod number, fresh and dry weight of whole groundnut plant in comparison to non-mycorrhizal pathogenic ones and the plant growth was better in 30 spacing than 15 cm. The colonization by AM fungi in both spacing pattern was higher in absence of pathogen S. rolfsii. However, pathogen’s presence decreased the mycorrhizal colonization considerably in 30 and 15 cm. The disease severity and incidence were recorded to be lowered when inoculated with mycorrhiza in pathogenic groundnut plants as compared to non-mycorrhizal pathogenic ones in both spacing pattern and incidence and severity was significantly lower in 30 cm as compared to 15 cm. Therefore, it was observed from our results that for management of soil-borne pathogens inoculation of AM fungi and spacing patterns are necessary.

Belowground interactions between plant roots, arbuscular mycorrhizal fungi (AMFs), and plant growth-promoting rhizobacteria (PGPR) can improve growth and yield under abiotic stress conditions. A pot factorial experiment based on completely randomized design with three replications was conducted to investigate the effects of AMFs (without inoculation as control, inoculation with Funneliformis mosseae and Funneliformis intraradices) and PGPRs (without inoculation as control Pseudomonas fluorescens p-169 inoculation) on roselle (Hibiscus sabdariffa L.) grown under water deficiency stress (WDS) [90% (I1), 75% (I2), 50% (I3), and 25% (I4) of field capacity as well-watered, mild, moderate, and severe stress, respectively]. The results showed that by applying WDS, the plant growth properties such as root and sepals’ dry weight, 1000-seed weight, seed yield, chlorophyll a, b, and total, carotenoids, and leaf water content was significantly reduced. The application of AMFs and PGPR under WDS conditions increased 1000-seed weight, seed yield. In response to WDS osmotic adjustment were provided in Roselle and under stress conditions. The highest seed yield was found under well-watered treatment by inoculation of F. mosseae without PGPR and the application of Pseudomonas fluorescens (6.37 and 6.51 g/plant, respectively). These results suggesting the antagonistic effects of AMFs and PGPR. AMFs inoculation under severe stress increased sepals dry weight compared to the non-inoculation. In conclusion, increased activity of enzymatic antioxidants and higher production of non-enzymatic antioxidant compounds, as well as photosynthetic pigments in symbiotic association with AMFs, can alleviate reactive oxygen species damage resulting in increased growth and yield parameters and improve water stress tolerance.

Background: Cow urine contains a growth stimulating substance IAA (Indole Acetic Acid) and is a compound from the auxin group. IAA has a good effect on plant growth. Arbucular mycorrhizal fungi have an important role for plants to overcome Al poisoning in marginal soils. Many of the marginal lands in Jambi Province are former coal mining areas. The role of AMF will be better if organic matter is added as a source of nutrition. Therefore, a study was conducted on the effect of a combination of biourine treatment with arbuscular mycorrhizal fungi on the growth and yield of forage in former coal mining areas.Methods: The experiment was conducted in a randomized block design, with six treatments and three replications. The treatments consisted of: (A) biourine 0% + AMF 0 g / clump (control), (B) biourine 0% + AMF 20 g / clump, (C) biourine 30% + AMF 0 g / clump, (D) biourine 30% + AMF 20 g / clump, (E) biourine 45% + AMF 0 g / clump, (F) biourine 45% + AMF 20 g / clump. The variables observed were leaf width, number of leaves, plant length, number of tillers and yield of dry forage. Result: The results showed that the treatment had a significant effect (P less than 0.05) on leaf width, number of leaves, plant length, number of tillers and yield of forage dry matter. The conclusion in this study is that E treatment (biourine 45% + AMF 20 g / clump) is the best.
