The recovery from moisture stress starts with an increase in water content in leaves reopening the stomata then the synthesis of photosynthetic proteins.

The occurrence of moisture stress during flowering, pollination, and grain-filling is harmful to most crops and particularly so to corn, soybeans, and wheat.
23.
Closing of the stomata also slows the rate of transpiration, which limits water loss and helps to prevent the wilting effects of moisture stress.
24.
There are four pathways that have been described that show the plants genetic response to moisture stress; two are ABA dependent while two are ABA independent.
25.
Cereal crops typically attain only about 25 % of their potential yield due to the effects of environmental stress, with moisture stress the most important cause.
26.
Leafmould, well-rotted organic manure, will help sustain healthy plant growth, while at the same time help to conserve soil moisture especially at times of moisture stress.
27.
Moisture stress also has an effect on stomatal openings of a plant, mainly causing a closure in stomata as to reduce the amount of carbon dioxide assimilation.
28.
Moisture stress has historically been associated with good fall color, and the year will be at least average over the entire state, and above average in the more drought-stricken regions.
29.
The effects of moisture stress on photosynthesis can depend as much on the velocity and degree of photosynthetic recovery, as it depends on the degree and velocity of photosynthesis decline during water depletion.
30.
Lowland cultivars appear more plastic in their morphology, produce larger plants if stands become thin or when planted in wide rows, and they seem to be more sensitive to moisture stress than upland cultivars.
