Generally, translocation of gibberellins is non-polar occurring through

The correct option is phloem.

Gibberellins are important plant hormones (phytohormones) that regulate various developmental processes, including stem elongation, germination, dormancy, flowering, and leaf and fruit senescence.
Unlike auxin, which exhibits polar transport (movement in one specific direction, typically basipetal), the translocation of gibberellins is non-polar. This means they can move in multiple directions within the plant body.

Gibberellins are synthesized in both young leaves/developing seeds (apical regions) and roots. Consequently, they are transported throughout the plant to facilitate growth:
1. Gibberellins synthesized in the roots are transported upward to the shoots primarily through the xylem (in the transpiration stream).
2. Gibberellins synthesized in the shoots are translocated to other parts of the plant, including downward transport, primarily through the phloem along with the bulk flow of sucrose and other organic nutrients.
Therefore, the general and primary route for the non-polar, multi-directional distribution and translocation of organic solutes and substances like gibberellins throughout the plant body is the phloem.
