water potential

An average annual surface water potential of 78.1 km3 has been assessed in this basin.

Water potential plays a key role in a plants nutrient uptake.

For more on this subject see water potential.

This, together with the sugars formed, lowers the water potential in the guard cells.

Water potential in movement of water between plant cells.

If stated, water potential is comparatively positive in the soil water.

A solution will have a lower and hence more negative water potential than that of pure water.

The pressure that is required to do so is equal and opposite to the water potential of the leaf.

Water potential has proved especially useful in understanding water movement within plants, animals, and soil.

These patterns are mostly likely a reflection of the plants' individual ability to maintain meristematic activity under low water potential.

This method relies on the fact that crack sizes have a range of different water potentials.

In many cases, matrix potential can be quite large and comparable to the other components of water potential discussed above.

There is greater water potential in the soil than in the cytoplasm of the root hair cells.

This is beneficial to the insects, as it reduces the stress of osmosis by reducing their own water potential.

When testing the water potential of a potato, a cork borer is used to maintain a constant surface area.

Moisture stress is more strongly related to water potential than it is to water content.

The water potential is created due to the ability of small solutes to pass through the walls of capillaries.

Such bleeding is similar to root pressure only sugars, rather than ions, may lower the xylem water potential.

The endosmosis of water continues till the water potential both in the root and soil becomes equal.

The main driving factor is the difference in water potential between the soil and the substomatal cavity caused by transpiration.

As a consequence,the cells of the roots develop lower water potential which brings in water by osmosis.

Ground water potential is meagre and water is saline in the sanctuary area.

These solutions typically have negative water potentials, relative to the pure water reference.

As a result of differences in water potential, water moves osmotically into the sieve tube element.

The species is relatively intolerant of low water potentials, and will grow poorly or not at all under water stress conditions.
