Wheat is the most important cereal crop and is the major
source of protein and calories in the daily diet. Drought is
the major abiotic stress that severely affect the production
of wheat worldwide. Morphology, physiology and biochemistry
of wheat is severely affected under drought stress condition.
The severity depends upon the time, stage and severity of
water stress. Drought stress produces reactive oxygen
species that cause the oxidative damage to the crops. Drought
stress causes reduction in germination percentage, reduce seed
vigor, early leaf senescence, early maturity, decrease chlorophyll
content, reduces photosynthesis, decrease starch
accumulation and decrease number of grains.
Morphological structures such as trichome and leaf waxiness,
stay green, accumulation of metabolites such as proline,
various enzymes viz; Superoxid.. View More»
