Other claims from this paper (10)
- Intervention effect Increasing medium macronutrient concentration progressively inhibited celery growth.
- Intervention effect Higher electrical conductivity lowered water content in celery roots, leaves, and petioles.
- Intervention effect Higher electrical conductivity left dry weight similar in celery roots, leaves, and petioles.
- Intervention effect Macronutrient stress did not change macronutrient concentrations in celery leaves, roots, and petioles.
- Intervention effect Mannitol accumulated in celery sink tissues under stress.
- Intervention effect Mannitol-1-oxidoreductase activity drastically decreased in celery sink tissues.
- Intervention effect Sucrose concentration in celery sink tissues was unaffected by macronutrient stress.
- Intervention effect Activities of sucrose-metabolizing enzymes in celery sink tissues were unaffected by macronutrient stress.
- Intervention effect Mannose-6-phosphate reductase and sucrose phosphate synthase activity increased in mature celery leaves under macronutrient stress.
- Mechanism Authors attributed stressed celery mannitol accumulation to lower sink catabolism and greater source leaf biosynthetic capacity.
