Question: 1 / 400

What do gibberellin synthesis inhibitors target in plant growth?

Stomatal closure

Flowering time

Cell division and elongation

Gibberellin synthesis inhibitors specifically target the processes of cell division and elongation in plants. Gibberellins are a group of plant hormones that play a crucial role in promoting growth by facilitating various developmental processes, including the elongation of stems and the division of cells in meristems. By inhibiting the synthesis of gibberellins, these inhibitors effectively reduce the overall growth rates of plants, impacting both their height and the development of new tissues.

The action of gibberellin synthesis inhibitors can also indirectly affect flowering time and other developmental processes, but their primary mechanism relates to halting or slowing down cell division and elongation. This is why they are considered essential tools in regulating plant growth, especially in agricultural practices where managing plant size and development can maximize crop yields or prevent unwanted growth behaviors.
