Arbuscular mycorrhiza enhances nutrient uptake in chickpea

Abstract

Arbuscular mycorrhiza fungi (AMF) colonize roots of host plants and promote plant growth due to improved uptake of nutrients. While the effects on P uptake are well known, the relevance of AMF for the uptake of other nutrients is less investigated. In the present paper we studied contents of N, P, K, Ca, Mg, Fe, Mn, Cu, and Zn in the legume chickpea in pot experiments during two seasons. Beside the control, the following treatment combinations: (i) the inoculation with the commercial AMF product 'Symbivit ® '; (ii) soil sterilization before inoculation, and (iii) mineral nitrogen application. A moderate level of AMF colonization (18-55% of roots), enhanced the nutrient uptake of chickpea. With P, Mn, and in 2006 also with K, Cu, and Fe the nutrient concentrations were also elevated, even along with a simultaneous increase in plant biomass. Soil sterilization or fertilization with N showed no significant effect on nutrient uptake and biomass production.

Increased protein content of chickpea (Cicer arietinum L.) inoculated with arbuscular mycorrhizal fungi and nitrogen‐fixing bacteria under water deficit conditions

“…The authors suggested that both bipartite and tripartite symbioses contributed to better plant nutrition, particularly regarding N and P, which resulted in improved plant growth. Enhanced nutrient uptake in inoculated chickpea has also been demonstrated by Farzaneh and colleagues …”

Root Proteomic Analysis of Grapevine Rootstocks Inoculated with Rhizophagus irregularis and Fusarium oxysporum f. sp. herbemontis

“…It has been shown that mycorrhizal plants may have fewer and shorter roots than non-mycorrhizal plants, since extraradicular AMF mycelium increases the volume of soil explored by the plant root system, allowing higher water and nutrient uptake (Locatelli et al, 2002). Therefore, these results confirm the ability of AMF to benefit plant growth, and the increase in shoot and root biomass is consistent with previous studies with grapevine rootstocks (Dalla Costa et al, 2010;Anzanello et al, 2011;Cangahuala-Inocente et al, 2011) or with other plant species (Lovato et al, 2006;Farzaneh et al, 2011;Cavagnaro et al, 2012;Evelin et al, 2012;Mohandas, 2012;Steinkellner et al, 2012). Anzanello et al (2011) detected an increase in shoot and root biomass in SO4 and P1103 rootstocks inoculated with AMF, and Dalla Costa et al (2010) also showed an increase in shoot biomass in SO4 rootstock inoculated with AMF.…”

Remediation of a heavy metals contaminated soil using mycorrhized and non‐mycorrhizedHelichrysum italicum(Roth) Don

“…Furthermore, Heggo, Angle, and Chaney () showed a reduction of Zn uptake in mycorrhized plants cultivated in contaminated soils, and the AM was responsible for a larger root uptake of Cd, Co, Pb, and Zn in plants grown in control soils. Farzaneh, Vierheilig, Lössl, and Kaul (), Bi, Li, Christie, Hu, and Wong (), and Nogueira, Nehls, Hampp, Poralla, and Cardoso () also showed an increase in Zn and Cu uptake by mycorrhized plants grown in not contaminated soils. This different behaviour of mycorrhiza regarding the uptake of metals can be attributed to their different concentration in the soil.…”
