CHILD DEVELOPMENT PEDAGOGY

Detailed explanation-1: -Fruit and leaf drop at early stages can be prevented by the application of the plant hormone or plant growth regulator (PGR) Auxin (Indole-3-acetic acid or IAA). They also promote abscission of mature and older leaves.

Detailed explanation-2: -Auxin delays abscission of young leaves and fruits. Its effect is through non-formation of abscission zone below a leaf or fruit. Abscission zone cuts off nutrients and water supply. However, auxin promotes the abscission of mature or older leaves and fruits.

Detailed explanation-3: -The use of auxins prevents dropping of fruit by maintaining the cells at the zone of abscission, preventing the synthesis of hydrolytic enzymes such as cellulose, which decompose the cell wall (Modise et al., 2009. Thuma, and R.

Detailed explanation-4: -Auxins are plant hormones, generated mostly by roots and stem tips. It aids in the prevention of early leaf and fruit drops. It accelerates the fall of mature and old leaves and fruits.

Detailed explanation-5: -Ethylene (plant hormone responsible for ripening and senescence), Abscisic acid-ABA (stress hormone), and Auxin (growth hormone) all play a symphony and cause ‘Abscission-falling/separation of leaf tissue’ from the plant.
