Which of the following could contribute to slower plant growth in saline soils?

Question

Quizplus · Accepted Answer

All of the choices listed contribute to slower plant growth in saline soils. The need to pull harder to obtain water from soil containing high concentrations of salts can limit both photosynthesis and cell expansion. Higher rates of respiration in roots that have to use energy to exclude salts from entering the xylem also limits energy available for growth. And higher salt concentrations in leaves can shorten their life-span and limit the plant's ability to produce energy through photosynthesis.
