Inoculation of cyclamen (Cyclamen persicum) and poinsettia (Euphorbia pulcherrima) with arbuscular mycorrhizal fungi and Trichoderma harzianum

Dual inoculation of peat based horticulture substrate with a mixture of four species of arbuscular mycorrhizal fungi and fungal biocontrol agent Trichoderma harzianum showed a significant positive effect on the growth and flowering of cyclamen plants. Inoculation substantially decreased plant mortality caused by spontaneous infection by the fungal pathogen Cryptocline cyclaminis. Plant mortality was also reduced by separate inoculation with arbuscular mycorrhizal fungi. Both separately inoculated agents positively affected the plant growth, although to a lesser extent. Very few significant effects of inoculation were observed on the growth of poinsettia plants cultivated from cuttings. Use of arbuscular mycorrhizal fungi together with the introduction of Trichoderma for inoculation of horticultural substrates is suggested to alleviate the inevitable effects of various stresses during the cultivation of horticultural crops.

Amf Inoculation

Arbuscular mycorrhizal fungi (AMF) is known to improve the growth of shallot (Allium cepa var. aggregatum) and strengthen the resistance of plants toward disease infection. This research aimed to find out the roles of AMF in suppressing the development of purple blotch disease caused by Alternaria sp. on shallot in Caturtunggal, Sleman, Yogyakarta. Inoculation of AMF either on fertilization of N, P, K or without fertilization treatment resulted on higher plant height and number of leaves compared to those without AMF inoculation. The plant inoculated with AMF had lower purple blotch disease intensity and disease progression than control and fungicide treatment. The result showed that AMF, in addition to act as the bio-fertilizer, is a potential to be a biocontrol agent.

Positive Effect

An experiment was performed in a completely randomized split-plot design using five lines of spring wheat (Triticum aestivum L.) (AW-774, AC Carberry, HY-162, Major and AAC Scotia) and two arbuscular mycorrhizal fungi (AMF) strains (Rhizoglomus irregulare and Glomus cubense). Two different inoculant forms (solid and liquid) for the G. cubense strain were evaluated. The main plot was AMF, and the subplot was spring wheat lines. Data on heading date, plant height, fresh, and dry biomass, yield, grain quality (chemical composition of the seeds, gluten, and sugar), root structure, and colonization by AMF were collected. The results show a positive effect of inoculation in comparison with the control treatment. The liquid and solid G. cubense inoculants provided better results than inoculation with R. irregulare. Fungus indicators were in agreement with root morphological parameters because of the effect induced by AMF activity. Yield increased significantly in the mycorrhizal treatments.

With the aggravation of volcanic ash Andosol acidification, artificial forage grass Dactylis glomerata L. gradual degradation, replaced by weed plant Anthoxanthum odoratum L., but the mechanism is unclear. In order to reveal the mechanism, this study used Andosol soil as matrix, explored the effects of arbuscular mycorrhizal fungi on D. glomerata and A. odoratum at different pH gradients in acidic Andosol by glasshouse experiment. The results show that the mycorrhizal colonization of D. glomerata strongly affected by soil pH, but the A. odoratum was not yet. The mycorrhizal symbiosis led to a positive effect on growth and P uptake of D. glomerata and A. odoratum. Consider to invasion and expansion of A. odoratum in severity acidic pasture is origin of this specificity on arbuscular mycorrhizal symbiosis in acidic soil other than D. glomerata.

Amf Inoculation

Abstract A pot experiment was conducted to study the extent of changes occurring in the nutrients, chlorophyll and protein of plants grown in cotton/alfalfa mixed culture as affected by inoculation with indigenous arbuscular mycorrhizal fungi (AMF). The experiment consisted of mycorrhizal treatments (with and without AMF inoculation) and three planting patterns (cotton monoculture, alfalfa monoculture, cotton/alfalfa mixed culture). Arbuscular mycorrhizal (AM) inoculum previously isolated from a rhizospheric soil of cotton, was a mixture of Glomus intraradices, G. viscosum, and G. mosseae. Results showed that total chlorophyll and protein concentrations, and nutrients content were higher in AM cotton plants compared with the non-AM control. Mixed culture had a positive effect on all the above parameters in cotton shoot. The highest values were noted in AM plants in the mixed culture. Improved chemicals and biochemical constituents in cotton led to an increase in dry matter production. The highest dry matter was observed in the AM mixed culture, and was significantly higher by 1.4 times than that of non-AM monoculture.

This research describes the production of carrot hairy roots for monoxenic culture of New Zealand arbuscular mycorrhizal fungi (AMF) Induction of hairy roots on mature carrot root sections was carried out using Agrobacterium rhizogenes isolate A4T that had been grown in either LauriaBertani (/ acetosyringone) or Yeast Mannitol medium (24 or 48 h incubation) Results showed both methods could initiate hairy root production The source of the carrots was one of the most important factors with mature freshly harvested carrots showing better hairy root production compared to coolstored carrots Dissection of the cortex to expose the cambium had a positive effect on the least optimal treatment

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.
