Shouldn't it be nastic movement (singular)? Richard001 (talk) 06:12, 24 March 2008 (UTC)

File:Oxalis Triangularis Photonasty Timelapse.ogv to appear as POTD soon

Hello! This is a note to let the editors of this article know that File:Oxalis Triangularis Photonasty Timelapse.ogv will be appearing as picture of the day on February 27, 2012. You can view and edit the POTD blurb at Template:POTD/2012-02-27. If this article needs any attention or maintenance, it would be preferable if that could be done before its appearance on the Main Page so Wikipedia doesn't look bad. :) Thanks! —howcheng {chat} 22:24, 25 February 2012 (UTC)

Picture of the day

Time-lapse video (played at 750× true speed) of the nastic movements of an Oxalis triangularis plant. The leaves open and close in response to varying light levels with the result that they are open during the day and are closed at night. This is true movement (i.e. not growth) and is non-directional with respect to the stimulus.Video: Richard Wheeler

Reference to plants / botany

This article doesn't explicitly state that nastic movements are a botanical feature; it is only clear through the image and descriptions of plant movement, and the fact that it is listed as a botanical stub. Treeturtle81 (talk) 12:49, 27 February 2012 (UTC)

Types of Nastic Response

Nyctinastic Haptonastic Hydronastics Chemonastic — Preceding unsigned comment added by 41.184.98.82 (talk) 21:03, 22 July 2012 (UTC)

Movement vs Color or Surface changes

Is chemonastic not also a term that could be applied to non-movement responses such as changing color or surface coating. Examples being French Hydrangeas or Pitcher plants. 131.204.254.84 (talk) 04:17, 13 November 2020 (UTC)

Also, isnt Photonasty and Nyctinasty basicly the same thing?131.204.254.84 (talk) 04:19, 13 November 2020 (UTC)

Directional or not?

"non-directional responses to stimuli” then “movement .. towards the source of light" 194.207.86.26 (talk) 08:09, 11 November 2023 (UTC)
