Photosynthetic opportunity cost and energetic cost of a rapid leaf closure behavior in Mimosa pudica

Rapid hydropassive opening and subsequent active stomatal closure follow heat-induced electrical signals in Mimosa pudica.

In Mimosa pudica L., heat stimulation triggers leaflet folding in local, neighbouring and distant leaves. Stomatal movements were observed microscopically during this folding reaction and electrical potentials, chlorophyll fluorescence, and leaf CO(2)/H(2)O-gas exchange were measured simultaneously. Upon heat stimulation of a neighbouring pinna, epidermal cells depolarized and the stomata began...

Image Processing of Leaf Movements in Mimosa pudica

In this paper the plant Mimosa pudica’s response to changed illumination conditions is being examined. An image processing routine, using the HSV color model and triangle intensity threshold segmentation, is developed to segment time-lapse image series of Mimosa pudica, quantifying the plant’s image pixel count as a measure of movement. Furthermore, the method of Farnebäck is used to estimate d...

A 5-deoxyflavonol derivative in Mimosa pudica

Mimosa pudica, Dionaea muscipula and anesthetics.

Some studies showed that anesthetics reduce the response of physical stimuli in Mimosa pudica and in Venus Flytrap (Dionaea muscipula), peculiar plants that have the ability to respond to touch stimuli. In this research we tested the effects of ketamine, lidocaine, diethyl ether, and amlodipine on the movements of Mimosa pudica and Venus Flytrap. With a literature review, we tried to bring elem...
