- Intervention effect Aboveground dry weight was somewhat reduced after three days at 0.15 soil water content.
- Intervention effect Continued water shortage markedly affected root height and root plasmalemma permeability.
- Intervention effect Potassium increased aboveground dry matter weight, stem thickness and leaf area.
- Intervention effect Potassium maintained relatively low leaf water potential and high leaf moisture content.
- Mechanism The authors attribute increased drought resistance to potassium-maintained leaf water status.
- Intervention effect At 0.30 soil water content, leaf yellowing appeared in rapeseed on potassium-deficient soil.
- Association With higher soil moisture, aerial calcium concentration increased without potassium application.
- Association With higher soil moisture, aerial potassium concentration decreased without potassium application.
- Intervention effect Moisture stress increased nitrogen and total amino acids in rape leaves.
- Mechanism Moisture stress led to more proline and glutamic acid formation in rape leaves.
- Association On low-potassium soil, moisture content had very little effect on yield.
- Association With potassium fertilizer, moisture content had a very significant effect on yield increase.
