Competition Science Vision
In Saxifrega, the rate of guttation is high during flowering. • In Colocasia
antiquoram, guttation is a normal process. • Motivated force for guttation is the
root pressure. • Region of loosely arranged cells present in a hydathodes is
called epithem.

Physiology of Woody Plants
Wieler (1893) listed nearly 200 species belonging to many genera, but his list
included examples of plants showing true root pressure, sap flow from wounds,
guttation, and even secretion from glandular hairs. It is necessary to distinguish ...

guttation. Hydathodes are present at the tip of the veins of leaves. Guttation is
generally found in herbaceous plants growing in moist, warm soil and under
humid conditions. When the absoprtion of water exceeds that of transpiration, ...
PROBLEM 10-19 What process in the plant is responsible for the phenomenon of
guttation? Solution : Droplets on a leaf commonly seen early in the morning are
usually assumed to be dew, which is water that has condensed from the air.

Example of guttation. The droplets of guttation water at the serrated margin of a
strawberry leaf (Fragaria sp.) were excreted during the night from the hydathodes
located at the tips. (After Sinnot and Wilson 1963) We may ask whether the plant
...

This loss of liquid water, known as guttation, occurs when transpiration is
negligible and available soil moisture is high. Guttation typically occurs at night,
because the stomata are closed, but water continues to move into the roots by
osmosis.
Guttation : The loss of water in the form of droplets along margins of leaves
through special pores, the hydathodes, is called guttation. 13. Water potential :
The difference between chemical potential of water at any point in a system and
that of ...
It is probable that guttation plays no significant part in the life of plants. However,
some workers believe that it may play a more essential role in shade plants of
tropical rain-forests than it does for plants of temperate zones. Under the shade of
a ...

DIRECT LOSS OF WATER BY THE PLANTS Guttation-ln herbaceous plants
when root pressure is high and transpiration is low, the water is forced out in the
form of drops from the margins or tips of leaves. This process is called guttation.
