- Intervention effect Low Cu decreased the dry weight of the whole barley plant compared with normal Cu.
- Intervention effect Low Cu decreased leaf chlorophyll content compared with normal Cu.
- Intervention effect Low Cu decreased leaf Cu and Fe concentrations compared with normal Cu.
- Intervention effect Low Cu decreased polyphenol oxidase activity compared with normal Cu.
- Intervention effect Low Cu increased ribonuclease and peroxidase activities and reducing sugar concentration compared with normal Cu.
- Intervention effect Combined deficiency of Cu and Ca further accentuated the low-Cu effects.
- Intervention effect Low Ca further reduced dry weight under excess Cu.
- Intervention effect Low Ca further reduced leaf chlorophyll and Fe concentrations under excess Cu.
- Intervention effect Low Ca increased sugar concentration and polyphenol oxidase and ribonuclease activities under excess Cu.
- Intervention effect Excess Ca further enhanced the Cu toxicity effects in barley.
- Intervention effect Resuming Ca supply partially alleviated the effects of Ca deficiency in barley leaf discs.
