How does drought stress affect plant growth

The main effect of drought stress on plant morphology is size reduction.Drought stress causes an imbalance between the antioxidant defense and the number of antioxidants.In addition, plants have to cope with abiotic stresses, such as drought.Growth of plant parts is reduced or delayed when green leaf area is removed.Rapid growth of roots, new leaf area or seed heads is evidence of a strong sink.

And last year's precipitation and defoliation (grazing) will affect this year's forage.In other cases, environmental stress weakens a plant and makes it more susceptible to disease or insect attack.Total leaf area and photosynthetic capacity of the plant.Alabama is in the midst of a drought with unusually warm fall weather and trees are beginning to exhibit signs of stress.Water channel proteins named aquaporins adjust root hydraulics in response to many stimuli, including drought stress.

In some cases, poor environmental conditions (e.g., too little water) damage a plant directly.Drought stress during this time can impact the eventual yield potential of the plant by reducing:Plant hormones (also known as.Drought results in leaf dehydration;How drought affects plant roots.
