Other claims from this paper (10)
- Association Salinity reduced tomato crop yield mainly through a decrease in dry matter accumulation rate during the early fruit-growing period.
- Observation Partial restoration of tomato growth occurred during the late phase of fruit development.
- Intervention effect Salt stress increased sucrose accumulation in both apoplastic and symplastic spaces of tomato, up to 15.
- Intervention effect Salt stress increased Na+ accumulation in the apoplast of tomato.
- Intervention effect Salt stress caused acidification in the apoplast of tomato.
- Intervention effect Salt stress caused a transient increase in starch content of tomato.
- Mechanism The decrease in apoplastic pH under salinity is hypothesised to cause a loss of insoluble acid invertase activity in tomato.
- Association Sucrose accumulation under moderate and high salinities resulted in a limiting step for tomato fruit growth.
- Association Sucrose accumulation in the symplast induced cytoplasmic sucrolytic activity in tomato.
- Association ADP-glucose pyrophosphorylase does not seem to be important in the control of tomato fruit growth under salinity.
