Other claims from this paper (16)
- Intervention effect Growth was negatively affected only at H2S concentrations of at least 0.4 μl I−1.
- Observation Shoots were a sink for H2S.
- Observation H2S uptake saturated as atmospheric concentration rose.
- Observation H2S uptake was high relative to other species.
- Intervention effect Atmospheric H2S substantially reduced root sulfate uptake after one week.
- Intervention effect Two weeks of sulfur deprivation reduced growth, more in shoots than roots.
- Intervention effect Sulfur deprivation increased shoot dry matter content.
- Observation Enhanced soluble sugars and starch largely accounted for higher shoot dry matter.
- Intervention effect Sulfur deficiency increased nitrate and free amino acid levels, particularly in shoots.
- Intervention effect Sulfur deficient plants had lower total lipid content in shoots.
- Intervention effect Sulfur deficiency left total lipid content in roots unaffected.
- Intervention effect Sulfolipid levels declined in roots and shoots.
- Intervention effect One week of H2S exposure abolished sulfur deficiency symptoms and restored growth.
- Observation Plants grew with H2S as their sole sulfur source.
- Intervention effect H2S exposure enhanced water-soluble non-protein thiols in roots and shoots irrespective of sulfate supply.
- Observation Plants grown with H2S as sole sulfur source had very low sulfate levels.
