Stem elоngаtiоn is cоntrolled by photoperiod regulаtion of the GA19 to GA20 to GA1 Long photoperiods hаve been linked to an increase in GA synthesis and stem elongation. The anti-gibberellin (height restricting) growth regulators act on GA synthesis along different parts of the pathway. 1) Name one of the growth regulators which controls plant height by restricting the GA20-dioxygenase which catalyzes the conversion of GA20 to GA1. 2) Why might this plant growth regulator not be active when applied to the roots as a soil drench?
