===================

Here is your answer sis:--------

There are five plant hormones with their functions:--------->

•A.) Auxin

2.) Promotes apical dominance of terminal bud.
3.) Promotes the formation of seedless fruits.....and this phenomenal is called as Parthenocarpy.
4.) Helps in root formation in stem cutting.

•B.) Cytokinin
============
1.) Helps in delaying in the ageing of plants.
2.) Increases the rate of cell division.
3.) Helps in breaking of seed dormancy.
4.) Helps in organ formation along with auxin hormone.

•C.) Gibberellin
=============
1.) Helps in seed germination and breaking seed dormancy.
2.) Helps in flowering in long-day plants under short day conditions.
3.) Helps in conversion of dwarf plants into tall plants.
4.) Promotes formation of male flowers in female plants.

•D.) Ethylene
===========
1.) Promotes ripening of fruits.
2.) Increases the rate of ageing.
3.) Promotes flowering in mango and pineapple.
4.) Promotes premature fall of leaves, flowers and fruits.

•E.) Abscisic acid
===============
1.) Promotes seed dormancy and bud dormancy.
2.) Promotes premature fall of leaves.
3.) Promotes ageing in plants.
4.) Suppresses the seed germination.

Hope it will be helpful to you!
