One of the commonly used plant growth hormone in tea plantation
1 Ethylene
2 Abscisic acid
3 Cytokinin
4 Auxin
Explanation:
Indole acetic acid produced in apex of plants and it migrates to regions of action since apical meristem is site for auxin synthesis and results in apical dominance, when shoot tips are removed they result in lateral bud formation. For this phenomenon, is widely applied in tea plantations and hedge making because when apical buds are plucked for processing tea more lateral buds produce and enhances plant growth

What promotes the abscission of older mature leaf?
1 Abscisic acid
2 Auxin
3 Ethylene
4 Cytokinins
