Leaf Movement in Cercis canadensis

A Leaf Detection Method Using Image Sequences and Leaf Movement

Besides harvesting the fruits, a very time demanding task is removing old leaves from cucumber and tomato plants grown in greenhouses. To be able to automate this process by a robot, a leaf detection method is required. One possibility for the detection is to exploit the different dynamic behaviour of leaves and stems in case they are excited by mechanical impulse such as an airstream. The obje...

Simultaneous monitoring of leaf growth and leaf movement.

Leaves experience predictable 24-h (diel) fluctuations in environmental factors such as light and temperature, as well as in energy availability. Accordingly, leaf growth is among the many processes regulated by the circadian clock. Despite the importance of leaf growth to the plant, it is relatively poorly understood, in large part due to the difficulty of tracking growth in leaves compared wi...

Potassium Flux and Leaf Movement in Samanea saman

Samanea leaflets usually open in white light and fold together when darkened, but also open and dose with a circadian rhythm during prolonged darkness. Leaflet movement results from differential changes in the turgor and shape of motor cells on opposite sides of the pulvinus; extensor cells expand during opening and shrink during closure, while flexor cells shrink during opening and expand duri...
