Other claims from this paper (11)
- Intervention effect Water stress disrupted tomato stem pith parenchyma.
- Observation Pith degradation starts in the upper stem and proceeds downward as stress persists.
- Intervention effect Rehydration did not reverse stressed tomato stem tissue damage.
- Observation Affected cells lost protoplast integrity before cell wall degradation.
- Intervention effect ABA enhanced pithiness following a short dehydration period.
- Intervention effect Kinetin caused severe wilting.
- Intervention effect Kinetin did not induce pithiness by itself.
- Intervention effect Kinetin enhanced pithiness when given after or during short water stress.
- Observation Under stress, ABA levels were higher in upper stems and young leaves than in lower shoot parts.
- Observation ABA levels rose before pithiness appeared.
- Mechanism The authors suggest ABA may trigger cellular degradation initiated by water stress.
