Abstract
Die Blattstiele der Haargurke führen Bewegungen aus, die die Blattspreiten mit ihrer Fläche senkrecht zum einfallenden Licht bringen (Phototropismus). Zeitraffung.
The movements of all types of climbing plants are extremely varied. They not only need specia sequences of movement to find a suitable support, but they must also be able to grasp it. The first pictures of our tendril-bearing, climbing plant gives an impression of these movements. They show how the tip of the sprout and the tendrils move in levely, ever-greater circles until they have attached themselves to a support.
