Why peanut leaves closed when it was dark

Dr. Tran Hop, former lecturer of University of Natural Sciences, National University of Ho Chi Minh City, said: Small leaflet of dual leaves of peanut with pistachio is formed by thin-walled cells. Occipital crust due to the stimulation of intense light intensity changes.

Explaining the phenomenon of peanut leaves closed when it was dark

When the light is dark to a certain extent, the lower half of the occipital chlorophyll produces strong permeability, causing the cell fluid to enter the cell slits, the swelling goes up, and the upper half of the occipital still in a state of urgency, so the leaves gradually subside, the leaves close.

Glutinous kumquat is stimulated by daylight, the fluid in the middle of the cell slits of the half part under occipital chlorophyll is sucked back, the cell wall is stressed, the strength increases, the strength of the half part The lower part of the lemongrass drops, so the small leaves expand.
