“…The reduced leaf area evidenced in our alkalinised L. tenuis plants (either in the presence or absence of NaCl) is in accordance with previous results obtained from several ornamental species, such as rose, Vinca, chrysanthemum and hibiscus treated with bicarbonate (HCO Cartmill et al 2007Cartmill et al , 2008. In addition, the neutral effect of NaCl, as sole stress source, observed on L. tenuis leaf area agrees with former results obtained on soybean (Dolatabadian et al 2011).…”

“…Whereas the relationship between salinity and morpho-anatomical plant responses has been explored to some extent, reports on the effects of alkaline or mixed salt-alkaline stresses are limited to few plant species, such as aspen (Mandre et al 2012), Pisum sativum (Gharsalli et al 2001), Catharanthus roseus (Cartmill et al 2008) and Phaseolus vulgaris (Valdez-Aguilar & Reed 2008).…”

Akaline, saline and mixed saline–alkaline stresses induce physiological and morpho‐anatomical changes in Lotus tenuis shoots

Saline, alkaline and mixed saline-alkaline conditions frequently co-occur in soil. In this work, we compared these plant stress sources on the legume Lotus tenuis, regarding their effects on shoot growth and leaf and stem anatomy. In addition, we aimed to gain insight on the plant physiological status of stressed plants. We performed pot experiments with four treatments: control without salt (pH = 5.8; EC = 1.2 dSÁm À1 ) and three stress conditions, saline (100 mM NaCl, pH = 5.8; EC = 11.0 dSÁm À1 ), alkaline (10 mM NaHCO 3 , pH = 8.0, EC = 1.9 dSÁm À1 ) and mixed salt-alkaline (10 mM NaHCO 3 + 100 mM NaCl, pH = 8.0, EC = 11.0 dSÁm À1

“…P is one of those minerals. An improvement in P absorption by mycorrhizal plants was observed by Cartmill et al (2008) and Neumann and George (2004) under HCO 3 − high levels and water stress, respectively. Better assimilation of P represents one of the main mechanisms developed by plants to enhance their tolerance to abiotic stresses (Hirrel and Gerdemann 1980;Ojala et al 1983), and for this reason a few authors have proposed mycorrhizal inoculation as a way to improve tolerance to high CaCO 3 levels in ectomycorrhizal and ericaceous plants (Clement et al 1977;Lapeyerie and Chilvers 1985;Leake and Read 1989).…”

“…The impact of CaCO 3 on mineral nutrient uptake in mycorrhizal roots is poorly documented. Cartmill et al (2008) observed an increase in mineral absorption by mycorrhizal roots in the presence of high levels of carbonate. Al-Karaki (2006) noticed a better mineral absorption by tomato (Solanum lycopersicum) mycorrhizal plants in the presence of another abiotic stress, salinity.…”

“…In our experimental conditions, we showed that whereas acid and alkaline phosphatase activities remained constant in mycorrhizal roots, these enzymatic activities were disturbed in non-mycorrhizal roots grown in the presence of CaCO 3 when compared to the control. However, no clear correlation between phosphatase activities and enhanced P absorption could be established, in contrast mycorrhizal Madagascar Periwinkle (Catharanthus roseus) (Cartmill et al 2008) and carrots (Daucus carota) roots (Koide and Kabir 2000), where better P nutrition was attributed to the improvement of root alkaline phosphatase activities. It would be interesting to investigate whether the higher P concentrations in the in vitro mycorrhizal chicory roots, compared to non-mycorrhizal ones, could be explained by the activity of AM fungal P transporters (Harrison and van Buuren 1995;Maldonado-Mendoza et al 2001).…”

Role of arbuscular mycorrhizal symbiosis in root mineral uptake under CaCO3 stress

et al. 2011

This study investigated the effects of increasing CaCO(3) concentrations (0, 5, 10, 20 mM) on arbuscular mycorrhizal (AM) symbiosis establishment as well as on chicory root growth and mineral nutrient uptake in a monoxenic system. Although CaCO(3) treatments significantly decreased root growth and altered the symbiosis-related development steps of the AM fungus Rhizophagus irregularis (germination, germination hypha elongation, root colonization rate, extraradical hyphal development, sporulation), the fungus was able to completely fulfill its life cycle. Even when root growth decreased more drastically in mycorrhizal roots than in non-mycorrhizal ones in the presence of high CaCO(3) levels, the AM symbiosis was found to be beneficial for root mineral uptake. Significant increases in P, N, Fe, Zn and Cu concentrations were recorded in the mycorrhizal roots. Whereas acid and alkaline phosphatase enzymatic activities remained constant in mycorrhizal roots, they were affected in non-mycorrhizal roots grown in the presence of CaCO(3) when compared with the control.

A greenhouse experiment was carried out during the spring–summer 2009 to test the hypotheses that: (1) arbuscular-mycorrhizal (AM) inoculation with a biofertilizer containing Glomus intraradices gives an advantage to overcome alkalinity problems, (2) mineral fertilization is more detrimental to AM development than organic fertilization on an equivalent nutrient basis. Arbuscular mycorrhizal (AM) and non-AM of zucchini (Cucurbita pepo L.) plants were grown in sand culture with two pH levels in the nutrient solution (6.0 or 8.1) and two fertilization regimes (organic or mineral). The high-pH nutrient solution had the same basic composition as the lowpH solution, plus an additional 10 mM NaHCO3 and 0.5 g L–1 CaCO3. Increasing the concentration of NaHCO3 from 0 to 10 mM in the nutrient solution significantly decreased yield, plant growth, SPAD index, net assimilation of CO2 (ACO2 ), N, P, Ca, Mg, Fe, Mn, and Zn concentration in leaf tissue. The +AM plants under alkaline conditions had higher total, marketable yield and total biomass compared to –AM plants. The higher yield and biomass production in +AM plants seems to be related to the capacity of maintaining higher SPAD index, net ACO2 , and to a better nutritional status (high P, K, Fe, Mn, and Zn and low Na accumulation) in response to bicarbonate stress with respect to –AM plants. The percentage root colonization was significantly higher in organic-fertilized (35.7%) than in mineral-fertilized plants (11.7%). Even though the AM root colonization was higher in organic-fertilized plants, the highest yield and biomass production were observed in mineral-fertilized plants due to the better nutritional status (higher N, P, Ca, and Mg), higher leaf area, SPAD index, and ACO2
