Keep in mind that guttation only releases less than 5% of excess water absorbed by the plants. is lost form the outer leaf tissues, water then moves in. As water. Guttation is caused due to a positive hydrostatic pressure (root pressure) which develops in the xylem ducts of the root. Takes place at high temperature Takes place at low temperatures. 3. On the other side of the story at the time when water is lost from the uninjured portions of the plants in the state of liquid then this method is given the name of Guttation. The process of guttation mainly occurs at night when the air is humid and temperatures are cooler. Guttation is the loss of water in a dilute solution form which consists salts and minerals and waters when transpiration is low. It never results in wilting. 5 min read.

(2003) compared guttation in barley plants infected by bacterial pathogens with uninfected plants and found that proteins in the guttation liquid of uninfected plants may prevent infection of the leaves by the pathogens. The Regulation of Transpiration: The Regulation of Transpiration There is a tradeoff between transpiration and photosynthesis Photosynthesis requires open stomata and the intake of CO 2. Transpiration and Guttation are two similar processes by which plants get water from their roots to the rest of the plant.

Transpiration Lab Exercise 9A Transpiration In this lab, you will measure transpiration under various laboratory conditions using a potometer. is lost form the outer leaf tissues, water then moves in. It is also lost by transpiration through the aerial parts of plants, mainly through the leaves. Guttation is influenced by humidity and availability of water while transpiration by a number of stomata, wind flow, and temperature; Transpiration enhance only pure water to evaporate while guttation enhance loss of sugars, amino acids, and salts; Transpiration occurs in terrestrial and herbaceous plants while guttation only in herbaceous plants; Transpiration does not involve Guttation occurs through the hydathodes on leaf tips while transportation takes place mainly through stomata.
