Other claims from this paper (16)
- Observation In controls, successive leaves had higher dry weight and zinc content.
- Observation Older control leaves lost dry weight after their maximum whereas younger leaves did not.
- Observation Control leaf zinc content rapidly declined after its maximum.
- Observation Leaf zinc content peaked before leaf dry weight.
- Observation Zinc concentration fell as each leaf emerged and unfolded, with wide differences among leaves.
- Observation Zinc deficiency produced chlorosis in the second trifoliate leaf at 25 days after germination.
- Intervention effect Zinc deficiency retarded third-leaf development.
- Observation Zinc deficiency arrested fourth-leaf development.
- Observation Oldest leaves gained abnormal weight after zinc deficiency began.
- Association Zinc moved more rapidly out of cotyledons and primary leaves in deficient plants.
- Association Deficient trifoliate leaves held much less zinc than controls.
- Mechanism Zinc concentration declined in deficient trifoliate leaves because dry weight grew while zinc amount scarcely changed.
- Observation Leaf zinc concentration was highest before leaf emergence and unfolding.
- Observation Copper moved out of control cotyledons and later out of primary and trifoliate leaves.
- Observation Leaves took longer to reach maximum copper amount than maximum zinc amount.
- Mechanism Zinc deficiency did not markedly change leaf copper concentration because copper accumulation tracked weight gain.
