e1“Cherry tomatoes(Lycopersicon esculentum var.cerasiforme)were cultured in deep flow hydroponic solution supplemented with graded levels(1.0-6.0 mg·L-1)of iodide(I-)”
e5“after the third week,the increase tended to slow down for the plants treated with high concentrations of I-(4.0-6.0 mg·L-1)”

Other claims from this paper (16)
- Intervention effect Iodine content in roots, leaves and fruits increased with increasing iodide concentration.
- Intervention effect Iodine content in roots increased rapidly during the first week after I-treatment.
- Intervention effect Iodine content in roots decreased in the second week after I-treatment.
- Intervention effect Iodine content in leaves increased significantly during the first three weeks after I-treatment.
- Intervention effect At 1.0 mg·L-1 I-treatment, iodine content in roots was higher than in leaves.
- Intervention effect At 2.0-6.0 mg·L-1 I-treatment, iodine content in roots was higher than in leaves at the early growth stage.
- Intervention effect At 2.0-6.0 mg·L-1 I-treatment, iodine content in roots was lower than in leaves at the later growth stage.
- Mechanism Iodine did not transfer to leaves until it had accumulated in the roots to a certain amount.
- Association Iodine content in ripe fruits could be predicted from the iodine content in leaves and roots by a dualistic linear regression equation.
- Observation Fruit iodine content was affected most in the first week after I-treatment.
- Intervention effect I-concentration of 2.0-6.0 mg·L-1 significantly affected TTC reduction in roots.
- Intervention effect Low I- concentrations of 1.0-2.0 mg·L-1 did not change chlorophyll content.
- Intervention effect Medium or high I- concentrations of 3.0-6.0 mg·L-1 significantly reduced chlorophyll content.
- Intervention effect Two weeks after treatment with I- at 2.0-6.0 mg·L-1, photosynthetic rate, stomatal conductance and intercellular CO2 concentration significantly decreased.
- Intervention effect Two weeks after treatment with I- at 2.0-6.0 mg·L-1, transpiration rate significantly decreased.
- Intervention effect Two weeks after treatment with I- at 2.0-6.0 mg·L-1, stomatal limitation value increased significantly.
