The plant hormones that would most likely be found in high concentrations in a mature slightly over-ripe fruit are cytokinin and ethylene.

  • The transition of a juvenile plant to a mature plant occurs through the growth, reproduction, and senescence of its fundamental organs.
  • Cytokinin is a growth hormone that is involved in cell division.
  • This hormone is produced by the cells that are constantly dividing that is the meristematic cells.
  • This hormone is mostly found in higher concentrations in fruits, flowers, and seeds.
  • Ethylene is responsible for the ripening of fruits

Cytokinin and ethylene

Explanation:

  • Cytokinin and ethylene are plant hormones would most likely be found in higher concentrations in a mature slightly over-ripe fruit

Cytokinin  

  • The plant growth hormone cytokinin promotes cell division. This hormone is produced in plant sections that are constantly involved in the cell division process.                      
  • The cytokinin are present in higher concentrations or proportions in the flowers, fruits, and seeds.  
  • They can also be present in the shoot and root apical areas.

Ethylene

  • Ethylene is a  gaseous plant growth regulator. It is produced in huge quantities by senescent tissues and ripening fruits.
  • When unripe bananas were placed near ripe bananas, they ripened faster. The chemical stimulating ripening was ethylene.
  • Ethylene is effective in fruit ripening because it increases the rate of respiration throughout the ripening process.
