e0“sunflower plants (Helianthus annuus L.) were grown in the presence or absence of Cd (20 micromol L(-1))”
e1“Although the shoot-to-root ratio of Cd was similar in both the AMF inoculated and non-inoculated plants, the total absorbed Cd was 23% higher in mycorrhizal plants”

Other claims from this paper (15)
- Intervention effect Cd decreased the growth of non-mycorrhizal sunflower plants without visible symptoms.
- Intervention effect The addition of Cd had no significant effect on mycorrhizal colonization or on the extra-radical mycelium produced by the AMF.
- Observation Cd accumulated mainly in the roots of sunflower.
- Observation Only 22% of the total Cd absorbed by sunflower was translocated to the shoots.
- Observation Cd accumulated to an average of 228 mg Cd kg(-1) in the shoots of sunflower.
- Intervention effect Total absorbed Cd was 23% higher in AMF-inoculated sunflower than in non-inoculated plants.
- Observation Cd concentration in the AMF extra-radical mycelium was 728 microg g(-1) dry weight.
- Intervention effect Despite greater Cd absorption, mycorrhizal sunflower plants had higher photosynthetic pigment concentrations and shoot P contents.
- Intervention effect Cd decreased Ca and Cu shoot concentrations in sunflower.
- Intervention effect Cd decreased N, Fe and Cu shoot contents in sunflower.
- Intervention effect Cd increased S and K shoot concentrations in sunflower.
- Intervention effect Cd induced guaiacol peroxidase activity in sunflower roots, in both mycorrhizal and non-mycorrhizal plants.
- Association The Cd-induced increase in guaiacol peroxidase activity was much more accentuated in non-mycorrhizal sunflower roots.
- Intervention effect Sunflower plants associated with G. intraradices were less sensitive to Cd stress than non-mycorrhizal plants.
- Intervention effect Mycorrhizal sunflowers showed some tolerance to excessive Cd concentrations in plant tissues.
