Water stress initially affects the most exposed parts of the plant, those with the highest water demand, such as leaves and young shoots.

Typical symptoms:
• General wilting of the plant, especially during the hottest hours of the day.

• Dry, brittle, or curled leaves.

• Necrosis at the edges and tips of leaves (a "burned" appearance).

• Premature leaf, flower, or fruit drop.

• Reduced leaf and fruit size.

• Slow or stunted growth.

Progressive dehydration reduces metabolic activity and weakens the plant.

Stages of development:
• Initial: loss of turgor and slight wilting during the hottest hours of the day.

Intermediate stage: dry, curled leaves and organ drop.

Advanced stage: widespread necrosis and significant reduction in growth.

Final stage: complete desiccation and death of the plant if the condition is not corrected.
