Guttation refers to the process of exudation of liquid droplets,
machinery and mouths of guttation, absorb and retrieve solutes which are
After one or two applications, plants grown in treated soil may produce toxic pollen, nectar and guttation
droplets for more than two seasons.
This slow exudation of liquid water is called guttation
occurs when transpiration is nil, such as under very high relative humidity conditions or at night (Nobel, 1999) (Fig.
Shortly after sunrise hoses can be tied between two turf vehicles and dragged across the field to knock dew and guttation
off the leaves.
and exudation of moisture from leaves is a function of soil moisture and plant water status (Taiz and Zeiger, 1991).
The slow exudation of liquid water from the hydathodes of a leaf.
In some extant angiosperms, guttation
occurs primarily in the young leaves, whereas older leaves do not consistently express guttation
When considering total dew in turfgrass systems, the possibility of wound exudates or guttation
from individual leaves make the potential contribution of plant-generated moisture much more important than in other crops.
For example, many studies show that teeth are strongly associated with the movement of water out of leaves via transpiration and guttation
daily dew or guttation
fluid removal), a decreased susceptibility of diseased plants to midday wilt when evaporative demand was high.
