Other claims from this paper (12)
- Observation Soils growing chlorotic sugarcane plantlets had pH 3.74 to 4.84.
- Observation Chlorotic and non-chlorotic plantlets had similar iron amounts despite symptoms resembling iron deficiency.
- Association Leaf manganese concentration correlated positively with exchangeable soil manganese.
- Association Leaf manganese concentration related to seasonal changes in leaf chlorophyll concentration.
- Association Leaf manganese concentration related to chlorosis occurrence.
- Observation Mature basal stalks contained up to 564.36 mg·kg(-1) DW manganese.
- Mechanism Excess manganese in parent stalks depressed leaf chlorophyll concentration in emerging plantlets.
- Observation Ratoon plantlet leaves accumulated 456.90-1626.95 mg·kg(-1) DW manganese and were susceptible to chlorosis.
- Observation Planted canes had low manganese accumulation of 94.64-313.41mg·kg(-1) DW and no chlorosis.
- Observation Chlorotic plantlets had active iron content of 3.39 mg kg(-1) FW.
- Observation Active iron content in chlorotic plantlets was 28.2% of control concentration.
- Mechanism Authors attribute ratoon sugarcane chlorosis primarily to manganese accumulated in parent stalks and secondarily to active iron deficiency.
