Question

Quizplus · Accepted Answer

Gibberellins are known to promote the elongation of fruits, including grapes, which could result in more loosely packed bunches. Spraying immature grape bunches with gibberellins may encourage the grapes to grow longer and more spaced out on the bunch. This would result in a looser bunch of grapes. Auxin, cytokinins, and abscisic acid are less likely to have this effect on grape bunches.
