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...
The Mimosa Pudica is an action plant that closes its leaves when given a stimulus. The plant integrates both sensing and actuating mechanisms, and the distinctive motion is about a hinge-like point, the pulvinus, making the characterization of the motion attractive. In this project, experiments were set up to measure the characteri stics of the plants in the goal to estimate the possibility to ...
Aqueous and methanol extract of two medicinal plants of Caesalpinia sappan L. and Mimosa pudica L. were evaluated for their antimicrobial activities against Staphylococcus aureus NCIM 5021, Bacillus subtilis NCIM 2010, Escherichia coli NCIM 2118, Pseudomonous aeruginosa NCIM 5029, Klebsiella pneumoniae NCIM 2707, Proteus vulgaris NCIM 2027, Candida albicans NCIM 3102 and Aspergillus niger NCIM ...
More than 270 years ago plants played the pivotal role in a remarkable discovery: Organisms possess within themselves a surprisingly accurate timing device that synchronizes physiology with the daily environmental cycle. The field of circadian biology arose from the curious observation of de Mairan in 1729 that the daily leaf movements of plants (Mimosa pudica) persisted for several days after ...
The seismonastic movement of Mimosa pudica is triggered by a sudden loss of turgor pressure. In the present study, we compared the cell cytoskeleton by immunofluorescence analysis before and after movement, and the effects of actin- and microtubule-targeted drugs were examined by injecting them into the cut pulvinus. We found that fragmentation of actin filaments and microtubules occurs during ...
