Other claims from this paper (10)
- Intervention effect Young sugarcane leaves developed significant chlorosis under excess manganese.
- Intervention effect Chlorophyll content fell with 250 μmol·L-1 Mn exposure.
- Intervention effect Young-leaf Fe content decreased significantly as Mn treatment concentration increased.
- Intervention effect Leaf Fe content after Mn treatment was 81.2–89.4% of control.
- Intervention effect Excess Mn increased root and stem Fe content significantly.
- Intervention effect Active Fe content and its ratio to total Fe declined significantly in young leaves under Mn stress.
- Intervention effect Active leaf Fe under Mn stress reached only 25.5–55.2% of control.
- Association Chlorophyll content correlated positively with active Fe in leaves under Mn stress.
- Intervention effect The young-leaf active Fe to Mn ratio declined under Mn treatment relative to control.
- Mechanism The authors attribute Mn-induced chlorosis to inhibited Fe acquisition, transport and activation.
