Fruit Plant Hormones Ageing List Commercial Including Weed Killing

Commercial uses of plant hormones include auxins for seedless fruit, ethene for fruit drop, cytokinins for anti-aging in produce, and gibberellins for delaying ripening, improving fruit quality, and aiding beer brewing.

Commercial uses of plant hormones include auxins for seedless fruit production, ethene for promoting fruit dropping, cytokinins to prevent ageing and thus preserve freshness, and gibberellins to delay ripening, improve fruit size/shape, and speed up malting in brewing.

Front List 4 commercial uses of plant hormones (not including weed-killing, rooting powder & controlling ripening).
Back Plant hormones uses:
  • Auxins used in production of seedless fruit
  • Ethene used to promote fruit dropping (e.g. in cotton, walnuts and cherries)
  • Cytokinins used to prevent ageing of ripened fruit & products such as lettuce
  • Gibberellins used to delay ripening and ageing in fruit, to improve size and shape of fruits and in beer brewing to speed up malting process
