When drought conditions begin, one can usually see the leaf tissue turning a lighter color green. As drought conditions progress, leaf tissue will begin to roll upwards trying to conserve as much water as possible. This action closes the stomata and lessens the amount of leaf tissue area for evaporation.

As conditions worsen, leaf tissue begins to die as it no longer has enough water to carry out normal photosynthesis and respiration activities. The same thing is happening in the root tissue, but not often seen by digging up the plants and looking at the roots.

As the plant tissue loses more and more water, the plant cells dehydrate and can no longer function. Death usually follows if the situation becomes worse. However, few people understand that it is possible for the live plant cells located in the phloem tissue to synthesize water during the respiration process. The plant cells in live tissue can synthesize water for cellular use and inhibit cellular tissue from dehydration.

When plant cells become toxic they become full of ethylene. The accumulation of ethylene in plant cells increases the toxic substance so that plant cells can no longer synthesize the amount of cellular water needed to keep them alive.

Applying a Stoller ethylene inhibitor on drought-stressed plants will increase their drought tolerance.
