fluid of endophyte-infected grasses," Phytochemistry, vol.
Molecular aspect of guttation
: involvement of contractile
After one or two applications, plants grown in treated soil may produce toxic pollen, nectar and guttation
droplets for more than two seasons.
This washes dew and guttation
fluid from leaf surfaces.
In the field, we inoculated plants when they reached the fourth true-leaf stage, after irrigating with about 12 mm of water during the two previous days to promote guttation
on the day of inoculation, and damaging the trichomes on the leaf surface by brushing the plants with a wooden stake (20 cm long and 2 cm wide) mounted at the end of an aluminum handle (60 cm long).
This slow exudation of liquid water is called guttation
The exit of this xylem water, termed guttation
, results in the formation of small droplets in the vicinity of the hydathodes.
: Exudation of liquid water from hydathodes fed by vascular xylem traces.
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
(e.g., Glenn & Takeda, 1989).
