Mobilise seed reserves
Embryo-derived GA signals the aleurone layer to produce hydrolytic enzymes such as α-amylase, which releases sugars from stored starch during germination.
Promote elongation and maturity
GA can lengthen internodes and grape stalks, increase fruit size and hasten maturity or seed production in juvenile conifers.
OlympIQ exam lens
- ✓GA → aleurone enzymes and starch mobilisation.
- ✓GA → stem/internode elongation.
- ✓GA applications include larger fruits and earlier conifer maturity.
OlympIQ trap
Do not confuse GA-induced α-amylase with auxin action.
