Ethene: Plant Growth and Ripening

Produced by Science & Plants for Schools (SAPS), this investigation looks at the effects of ethene of fruit ripening.

Ethene is a colourless gas and is produced by plants, acting as a plant growth substance. Its presence can be detected using a simple bioassay using germinating seedlings. Details of this assay are included in the resource.

Some suggestions for investigations include:
• detecting the release of ethene from ripening fruits
• accelerating and delaying leaf fall in cut flowers
