Claim · model-written summary
Adding sodium chloride decreased transpiration rate by the same magnitude as potassium chloride, indicating the short-term response is not specific to potassium.
Verbatim
t0“Triticum aestivum”
e4“An addition of potassium chloride to potassium deficient wheat plants resulted in a decrease in the transpiration rate of up to 50% within two hours”
e5“Comparative tests with sodium chloride resulted in a decrease in transpiration rate of the same magnitude”

Other claims from this paper (5)
- Association Plants with high potassium amounts had the lowest transpiration rates.
- Association Shoot/root ratio, stomatal frequency and stomatal aperture were correlated with leaf potassium concentration.
- Association In Triticum, no correlation was evident between transpiration and leaf sodium concentration.
- Intervention effect Adding potassium chloride to potassium-deficient wheat decreased transpiration rate by up to 50% within two hours.
- Mechanism The observed transpiration effect is supposed to be due to changes in stomatal aperture.
