Richmond- lang effect-
Cause- It was found that increased cell-wall invertase activity which occurs in response to cytokinin is both necessary and sufficient for the inhibition of senescence.
This effect is discovered by Richmond & Lang in 1967. Acc. to this effect the delay of senescene of leaves and other parts takes place by the help of plant growth regulator cytokinin.
Leaf senescence is a developmental process actively initiated as part of an age-dependent genetic program or in response to environmental stress which leads to apoptosis.

Retardation of senescence leads to retard the rate of degradation of chlorophyll,keeping them productive longer. It has an effect on protein synthesis and mobilising nutrients.
