Another problem is drought stress and a lack of watering.

Can provide some protection to plants during chilling and drought stress.

Meanwhile, try to be consistent about watering; plants under drought stress often drop their lower leaves.

This is the case when crops are sensitive to drought stress throughout the complete season, such as maize.

Grass meadows and cultivated crops are showing signs of drought stress.

Mr. Roth said none of his grapes were showing drought stress.

Thus in many parts of the world including the United States, plants may frequently encounter drought stress.

On such soils some plants may experience drought stress after only a few days without water.

A limited root system will accelerate the rate at which drought stress develops.

The prior environment of a plant also can influence the development of drought stress.
