NAA ( Napthalene acetic acid) and 2,4-D( Dichloro phenoxy acetic acid)...

One of the synthetic auxins:
Synthetic auxins are chemicals that mimic the effects of naturally occurring auxins in plants. One of the most widely used synthetic auxins is 2,4-Dichlorophenoxyacetic acid (2,4-D).

Plant Growth and Development:
Auxins play a crucial role in regulating plant growth and development. They are involved in various processes such as cell elongation, root initiation, apical dominance, and fruit development.

From Past 28 Years:
Research on the effects of synthetic auxins like 2,4-D on plant growth and development has been ongoing for the past 28 years. Scientists have been studying the mechanisms by which synthetic auxins regulate various physiological processes in plants.

Questions:
Some of the key questions that have been explored over the past 28 years include:
- How do synthetic auxins affect plant growth at the cellular level?
- What are the long-term effects of synthetic auxin application on plant development?
- How can synthetic auxins be used to improve crop yields and quality?

Explanation:
Through extensive research and experimentation, scientists have gained a better understanding of the role of synthetic auxins in plant growth and development. This knowledge has led to the development of new agricultural practices aimed at maximizing crop productivity and sustainability.
