Discussion had started by posting collage of these two Phyllanthus pictures (above picture was taken at 3.33 PM and below picture was taken at 5.22 PM yesterday by Dr. Arunan)…
These two pictures were screened and many questions were asked like. Can we catch the exact sleeping time of Phyllanthus plant.
The Angle was measured by drawing two lines ( one line parllel to branch and another red line parallel to midrib of a leaf ) two leaves were taken as a preliminary observation and similarly two same leaves were choosen in below picture and Angle was measured…
We found that there’s a difference in Angle so we had concluded that sleeping Activity has initiated as leaves had started to fold by 5.22 PM.
So can we catch the exact sleeping time of Phyllanthus plant by measuring angle objectively
Significant change in angle will be consider as point at which sleep has just started so called TITRATION OF SLEEP IN PHYLLANTHUS PLANTS
Right hand side Graph was also made to propose a model how angle will changed.
According to the graph Angle will remain same from 10AM to 5PM . And change in Angle will be seen after 5 PM that’s at 6PM angle will reduced to 70°. Hence we can consider this significant change in angle as a point at which sleeping Activity started…
What others say?..
Phyllanthus photo was taken from the same angle and pictures were clicked at different intervals of time and one leaf was targeted to measure the angle using an online protractor…
Hence we got to see this graph… this graph is quite similar to the graph made earlier on the right hand side of Phyllanthus plant collage.
Where the angle was remained same from 10 am to 5pm and here in this graph also we can see the same pattern …
@Aswathy Cube Butterfly drew Phyllanthus sleep wake cycle graph also which is shawn here in red color. Blue color graph shows an activity pattern of fruit flies…
Excellent way of connecting two model systems…
