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.
Mechanism The decline in spikelets per panicle at high copper was attributed to lower dry mass per stem and spikelet survival.
Association Total rice biomass fell significantly as copper concentration increased.

Other claims from this paper (11)

Intervention effect Silicon concentration up to 1780 μM had no detrimental effect on sorghum dry matter yields.
Intervention effect At 2670 and 3560 μM Si, shoot dry matter yield of sorghum decreased.
Observation Sorghum grown with 3600, 5400 and 7200 μM Mn showed marked visual toxicity symptoms in shoots but no effects on roots.
Association Root dry matter yield of sorghum decreased more than shoot dry matter yield under 3600, 5400 and 7200 μM Mn.
Intervention effect Silicon at 1780 and 3560 μM partially alleviated the toxicity symptoms and dry matter yield reductions caused by 3600 and 5400 μM Mn.
Observation No Si level overcame the severe effects induced by 7200 μM Mn in sorghum.
Intervention effect High Al (296 μM) reduced root dry matter yields of sorghum.
Intervention effect Silicon at 1068 μM was required to overcome the Al effect on root dry matter yield of NB9040 sorghum.
Intervention effect Silicon at 3560 μM was required to overcome the Al effect on root dry matter yield of Martin sorghum.
Intervention effect Added Si decreased the shoot/root dry matter ratios of sorghum that were high under toxic Mn and Al.
Observation Silicon effects were not sufficient to completely overcome the Mn and Al toxic effects on sorghum.

Other claims from this paper (5)

Intervention effect A stepped canopy increased bell pepper yield per area relative to a uniform arrangement.
Intervention effect A stepped canopy produced higher fruit set per plant.
Intervention effect Under stepped arrangement, increasing density from 6 to 8 plants per square metre did not boost yield.
