Adaptive Anatomical Structure for Nastic Movement in Mimosa Pudica L

In order to study the adaptive anatomical structures during nastic movement of Mimosa pudica L., anatomical structures of main pulvinus, common petioles, rachis and leaflets were compared with Albizia julibrissin Durazz. (taken as control). The anatomical structures of main pulvinus and common petiole of M. pudica were different from that of A. julibrissin. Upon stimuliti, the protoplast volume...

Contractile Characteristics of Mimosa pudica L.

The force-velocity characteristics of the primary pulvinus of Mimosa pudica have been determined using a new polytonic measurement technique. The contractile characteristics were determined from a modified form of Hill's equation (Hill, A. V. 1938. Proc. Roy. Soc. London B126: 136-195) describing the physiological contractile behavior of animal muscle. The values of the resulting Hill's constan...

Mechanoreceptor Cells on the Tertiary Pulvini of Mimosa pudica L.

Special red cells were found on the adaxial surface of tertiary pulvini of Mimosa pudica and experiments performed to determine the origin and function of these cells. Using anatomical (light, scanning electron and transmission electron microscopy) and electrophysiological techniques, we have demonstrated that these red cells are real mechanoreceptor cells. They can generate receptor potential ...

Learning in Plants: Lessons from Mimosa pudica

This article provides an overview of the early Mimosa pudica literature; much of which is in journals not easily accessible to the reader. In contrast to the contemporary plant learning literature which is conducted primarily by plant biologists, this early literature was conducted by comparative psychologists whose goal was to search for the generality of learning phenomena such as habituation...
