Other claims from this paper (11)
- Intervention effect At reduction division, increasing sulfur dioxide decreased spikelets per panicle.
- Intervention effect At reduction division, increasing sulfur dioxide decreased 1,000-kernel weight.
- Intervention effect Sulfur dioxide at 0.5 and 5 ppm significantly affected the percentage of ripened grains.
- Intervention effect At flowering, higher sulfur dioxide concentrations reduced the percentage of ripened grains to some extent.
- Intervention effect At flowering, sulfur dioxide slightly reduced panicle number per plant.
- Intervention effect Other yield components were unaffected by fumigation at flowering.
- Intervention effect Seed germination was unaffected by sulfur dioxide in most plots.
- Observation Seedlings from the 5 ppm flowering-stage plot had somewhat translucent seminal roots.
- Intervention effect Leaf sulfur content rose in proportion to sulfur dioxide exposure concentration.
- Intervention effect Kernel sulfur content was not influenced by fumigation.
- Mechanism The authors infer that sulfur accumulated in leaves was not translocated to kernels.
