Other claims from this paper (9)
- Intervention effect Leaf thickness, leaf vein cross-sectional area, and xylem area rose then fell with potassium rate and peaked at K3.
- Intervention effect Potassium increased basal stalk and ear-pedicel vascular bundle cross-sectional area, number, and area.
- Intervention effect The stalk vascular area ratio was highest under K2.
- Intervention effect The ear-pedicel vascular ratio was higher under K2 and K4 than under other treatments.
- Intervention effect Ear-axis vascular bundle number and area first increased and then decreased with potassium fertilization.
- Intervention effect Ear-axis total vascular bundle area was higher under K2 and K3 than other treatments.
- Intervention effect Potassium increased stem and ear-pedicel bleeding intensity, highest under K2 at filling.
- Association Stem and ear-pedicel vascular bundle area and number correlated positively with grain yield.
- Association Ear-axis total vascular bundle area correlated positively with 1000-grain weight.
