“…The degree of the AMF colonization of lettuce roots detected in our experiment is lower than described by BAslAm et al (2011a), who cultivated lettuce in a mixture of vermiculite, sand and peat, obtaining the root colonization in a range of 56 to 61% when a commercial inoculum containing G. mosseae and G. intraradices had ben applied to the growing medium, and 65% in roots of plants inoculated with G. fasciculatum. The reason for the varying degree of the colonization of plant roots by AMF may be the concentration of P in a nutrient solution and the type of substrate (cwAlA et al 2010, mABoko et al 2013). The current experiment did not prove any significant effect of the P concentration in the nutrient solution on the mycorrhizal frequency.…”

“…A positive effect of AMF on yield was also observed in the cultivation of tomato (dAsgAn et al 2008) and pepper (ikiz et al 2009). On the other hand, mueller et al (2009) andmABoko et al (2013) showed that arbuscular mycorrhiza did not have any effect on the nutrient uptake, growth and yield of tomato grown in soilless culture. The reason for these discrepancies is probably the degree of colonization of plant roots by AMF in hydroponic cultures, which depends i.a.…”

Kowalska I., Konieczny A., Gąstoł M. 2015. Effect of mycorrhiza and the phosphorus content in a nutrient solution on the yield and nutritional status of lettuce grown on various substrates. J. Elem., 20(3): 631-642. AbstractThe potential of mycorrhization of lettuce in hydroponic conditions was tested in a two-year experiment carried out in the autumn of 2011 and 2012 in an unheated foil tunnel. The experimental factors were as follows: inoculation of plants with arbuscular mycorrhizal fungi (AMF+ or AMF-), concentration of phosphorus in a nutrient solution (10 or 40 mg dm -3 ) and the type of substrate (rockwool or coconut coir). The inoculation of plants with arbuscular mycorrhizal fungi of the genus Glomus was performed twice, i.e. while sowing seeds and when planting lettuce plants into mats. The impact of the experimental factors on the degree of colonization of lettuce roots by AMF as well as the yield and nutritional status of plants, expressed as the content of macro-and micronutrients, was studied. The mycorrhizal frequency in roots inoculated with AMF reached 51.36%. The nutrient solution concentration of phosphorus and the type of substrate did not have any significant effect on the mycorrhizal frequency. There were no differences in the yield and content of macronutrients in lettuce leaves between plants inoculated and not inoculated with AMF (AMF+, AMF-). Likewise, there were no differences in the yield caused by different phosphorus levels in the nutrient solution or the types of substrate. Plants growing on rockwool accumulated significantly less P, Ca and Mg in comparison to plants growing on coconut coir. Regarding Ca, this effect was especially pronounced in plants receiving the nutrient solution with a higher concentration of P, i.e. 40 mg dm -3 . Mycorrhiza had a significant effect on the content of Cu, Mn and Zn in lettuce leaves. Inoculated plants were characterized by a lower content of these micronutries compared to plants grown without AMF. With respect to Mn, this effect was particularly evident in plants grown on rockwool.

“…The shoots of the mycorrhizal plant had significantly higher concentrations of P, N, K and Mg but lower Na than those of non-mycorrhizal plants (Abdel-Fattah and Asrar, 2012). Other authors (Maboko et al, 2013) showed no significant concentration of minerals in the leaves of mycorrhizal plants and a lack of increased nutrient uptake by plants that were not inoculated with AM Fungi. The nutrient contents of tomato fruit varied depending on the time of inoculation with AM Fungi.…”

The aim of study was to investigate the effect of two mycorrhizal fungus species Claroideoglomus etunicatum and Rhizophagus intraradices on the uptake of macronutrients and on the growth and yield of tomato hybrid plants cultivated in an ecological system. The experiment was carried out at an ecological farm in Grądy in the Lublin province of Poland, for three years (2015-2017). The experimental treatments included plants inoculated with Claroideoglomus etunicatum, Rhizophagus intraradices and plants without mycorrhizal inoculation used as a control. The mycorrhization of tomato roots with Claroideoglomus etunicatum and Rhizophagus intraradices resulted in an improved uptake of Ca and K through the plants. The length of the tomato roots, especially for the cultivars treated with Claroideoglomus etunicatum, were statistically longer than those of the control. Tomato roots inoculation with both of the studied mycorrhizal fungus strains significantly influenced the number of tomato leaves and improved the health status of the plant. The yield of tomato was not significantly affected by mycorrhization but Claroideoglomus etunicatum, to a greater extent than Rhizophagus intraradices reduced the yield of diseased fruit compared to the control. Among the studied mycorrhizal fungus species, better results were obtained with the application of Claroideoglomus etunicatum as compared with Rhizophagus intraradices for all examined features. Mycorrhizal inoculation contributed to the better growth of the plants, it improved their health and may be beneficially applied in the ecological production of tomatoes.

“…Kowalska et al 33 found that the mycorrhizal frequencies in tomato roots inoculated with AMF were 35.79 and 50.82% at 82 and 112 days after transplanting, respectively. Maboko et al 47 attained 78.2% colonized tomato roots growing in coconut and 77.7% growing in sawdust. Cwala et al 48 found that the colonization level of tomato roots was ranged from 14 to 25% in hydroponic cultivation.…”
