- - - - Delays senescence
      - (w/ cytokinins) can elongate apples, improving shape
      - Elongate grape stalks, less compacted, grapes get bigger
    - - Maltose is created from starch by amylase, switched on and sped up by giberellin. Malt is produced by drying and grinding seeds
    - - Increases internode length, increasing sugar cane yield
    - - Increase and speed up seed formation in slow cycling plants
      - Preventing giberelling productions can keep flowers short and stocky
      - Preventing giberellin production prevents lodging (stems bending over due to water weight)
- - - - Phototropism
        
        shoots grow towards the light
      - Geptropism
        
        roots grow towards the pull of gravity (anchoring them)
      - Chemotropism
        
        pollen tubes grow down the style, attracted by chemicals towards the ovary
      - Thigmotropism
        
        shoots of climbing plants towards solid structures
      - directional responses
    - - non-directional responses
- - - - The seed absorbs waters, the embryo releases giberellin
      - Allows production of amylase, converting starch into maltose which can then be converted to glucose
