Other claims from this paper (9)
- Observation Low sulfur caused visible sulfur-deficiency symptoms.
- Intervention effect Sulfur deficiency changed electrophoretic leaf protein patterns, especially after three weeks.
- Intervention effect Low molecular weight leaf protein fractions increased under sulfur deficiency.
- Intervention effect The relative amount of high molecular weight leaf proteins decreased under sulfur deficiency.
- Intervention effect Sulfur-deficient plants had fewer isoenzyme components than sulfur-adequate plants.
- Intervention effect Malate dehydrogenase and acid phosphatase isoenzymes were synthesized to similar degrees at both sulfur levels.
- Intervention effect Most studied enzymes had lower specific activity under sulfur deficiency, especially after three weeks.
- Intervention effect Glutaminate dehydrogenase, succinate dehydrogenase, and a-ketoglutarate dehydrogenase activities were not significantly affected by sulfur supply.
- Observation Acid phosphatase and malate dehydrogenase specific activities remained relatively high at low sulfur supply.
