Osmotic adjustment means that drought, low temperature, high temperature, salinity and other adversities will directly or indirectly form water stress on plants. Under water stress, certain plants can actively accumulate various organic or inorganic substances to increase the concentration of cell sap , Reduce the osmotic potential and increase the water absorption of the cells, thereby adapting to the water stress environment.
According to the above definition, which of the followings does not belong to osmotic adjustment?
The first response of maize plants to drought stress is to avoid low water potential and reduce light energy capture by stomatal closure
