wilting

wilting

a plant state in which a loss of TURGOR by cells of the leaves and other soft tissues causes drooping. The condition is caused by a lack of water (see WATER STRESS), either through drought in the soil, or a disease (such as fungal wilt) which blocks the XYLEM VESSELS in the stem or leaves.

wilting

dehydration of plants to the point where the leaves lose their turgor and hang limply. Can happen in living plants which later return to normal, or to cut plants before they are fed out. Thought to be a factor in increasing toxicity.
