nyctinasty मीनिंग इन हिंदी

Studies of nyctinasty were particularly burdensome, to Darwin's rest as well as to the plants:
He earlier research largely dealt with physiology of plants; working with subjects such as : growth rhythm, nyctinasty, geotropism, leaf positioning, electrical potential differences on cell walls, et al.
Nastic movements results from differential cell growth ( e . g . epinasty and hiponasty ), or from changes in turgor pressure within plant tissues ( e . g ., nyctinasty ), which may occur rapidly.
"D . keniodendron " protects itself against freezing temperatures by closing its leaves when it becomes cold ( at night ) and opening them when it is warm ( during the day ); an adaptive insulation method sometimes called nyctinasty, or a night bud.
