At night, when temperatures are cool or when the air is humid, less moisture evaporates from the leaves. A) transpiration rates are high B) root pressure exceeds transpiration pull C) preceding evening was hot, windy, and dry D) roots are not absorbing minerals from the soil Transpiration causes the development of a negative pressure in the xylem of the plant. Continuity of the Process: Guttation does not occur when the plant is under water stress (conditions of water deficiency). Guttation only occur through the margin of the leaves while transpiration from all parts of the body; Transpiration is favored by dry conditions while guttation is not favored by dry conditions; Humid conditions tend to favor guttation while reduces transpiration rate since it does not support the diffusion; Guttation drops can easily be mistaken for dew drops because both occur in the morning. Some sources say guttation occurs whenever there is enough moisture to create root pressure. Guttation is the exudation of drops of xylem sap on the tips or edges of leaves of some vascular plants, such as grasses. Root pressure is studied by removing the shoot of a plant near the soil level. The transpiration rate must be slow in order for the root pressure to be higher than the transpirational pull.

If this does not happen and the water vaporizes on the leaf, then this may have a harmful effect because a layer of sugars and salts will remain on the leaf surface as small white spots. The process of guttation mainly occurs at night when the air is humid and temperatures are cooler. Transpiration stops at night when the stomata on leaves close. Water is lost in the form of vapors. Plants also use stomata for photosynthesis, and since photosynthesis does not occur at night (after all, it cannot happen without the sun), the stomata close.
