Which of the following is NOT the function of cytokinin ?
Which of the following is NOT the function of cytokinin ?
Options
- AIt promotes cell enlargement besides cell division.
- BIt induces RNA synthesis and formation of interfascicular cambium.
- CIt hastens the senescence and abscission processes in plant organs.
- DIt promotes the growth of lateral buds and controls apical dominance by cell division.
Correct answer
C. It hastens the senescence and abscission processes in plant organs.
Step-by-step solution
Cytokinins are plant growth promoters that play a crucial role in cell division and enlargement.
They help in overcoming apical dominance by promoting the growth of lateral buds.
Cytokinins are well known for delaying the senescence (aging) of leaves and other plant organs by promoting nutrient mobilization, a phenomenon known as the Richmond-Lang effect. They do not hasten senescence or abscission; rather, hormones like abscisic acid and ethylene are responsible for hastening these processes.
Therefore, the statement that cytokinin hastens senescence and abscission is incorrect.
