Effects of Soil Cu Concentration on Growth and Development and Yield Formation of Rice

XU Jia-kuan; Lianxin Yang; Zhiqiang Wang; et al. Zhongguo shuidao kexue 2005

Other claims from this paper (8)

Intervention effect Low soil copper concentrations had little effect on rice height, main stem leaf number, internode number and heading date.
Intervention effect At 400 mg/kg soil copper, rice growth was seriously inhibited, with greater damage as copper concentration increased.
Association Rice yield loss increased significantly with soil copper concentration.
Intervention effect Lower copper concentrations reduced spikelets per panicle.
Intervention effect Higher copper concentrations decreased panicle number and spikelets per panicle.
Association Panicle number decreases at high copper were related to delayed establishment and reduced tillering.
Association Total rice biomass fell significantly as copper concentration increased.
Intervention effect Economic coefficients generally did not decrease significantly except at very high copper concentration.
