Functions of plant hormones:

 { \red{ \bf{  Auxins: }}}

 { \green{ \bf{   Site\:  of \: Synthesis:}}}

Synthesized primarily in shoot apical meristems and young leaves.

 { \green{ \bf{  Functions: }}}

Promote cell elongation.

Suppress the growth of lateral buds.

Delay fall of leaves.

Induce formation of parthenocarpic fruits.

 { \red{ \bf{Gibberellins:   }}}

 { \green{ \bf{   Site\:  of \: Synthesis:}}}

Synthesized primarily in the meristems of apical buds and roots.

 { \green{ \bf{  Functions: }}}

Help in stem-elongation.

Break dormancy of seeds and buds.

Delay senescence.

Induce parthenocarpy.

 { \red{ \bf{  Cytokinins: }}}

 { \green{ \bf{   Site\:  of \: Synthesis:}}}

Synthesized primarily in roots and transported to other organs.

 { \green{ \bf{  Functions: }}}

Stimulate cell-division and cell enlargement.

Prevent ageing of plant parts.

Inhibit apical dominance.

 { \red{ \bf{   Ethylene:}}}

 { \green{ \bf{   Site\:  of \: Synthesis:}}}

Synthesized in senescent leaves and flowers, germinating seeds and ripening fruits.

 { \green{ \bf{Functions:   }}}

Induces fruit ripening.

Promotes senescence.

 { \red{ \bf{ Abscisic \: acid:  }}}

 { \green{ \bf{   Site\:  of \: Synthesis:}}}

Synthesized in green fruits and seeds at the beginning of the wintering period.

 { \green{ \bf{ Functions:  }}}

Induces dormancy of buds and seeds.

Inhibits seed-germination and development.

Stimulates closing of stomata.
