- 15 postharvest effects of ethyleneIncrease respiration rate
Fruit Ripening
Yellowing & Senescence
Breaks dormancy
Inhibits sprout elongation - 2Climacteric vs non-climacteric Ethylene production increases at ripening Ref?Wills et al
- 3Chemical equation of ethyleneC2H4
- 4Effect of additional ethylene on climacteric cropsPeak occurs earlier
- 5Effect of additional ethylene on non-climacteric fruitcauses a respiration peak and increases size
- 6response process of adding ethyleneautocatalytic process
- 7What does 1-MCP do?Stops ethylene binding to receptors
Inhibits response but not production - 8What does AVG do?Inhibits production of ethylene
Does not stop response to external ethylene - 9References showing delays in ripening/senescenceGuillien et al, 2007 - ripening in tomato fruit
Koukounaras et al, 2009 - senescence in rocket leaves - 10Ethylene is often used instead of CIPC. What 4 things does ethylene do to potatoes?Reduces dormancy length
Short term increase in respiration
Inhibits elongation of sprouts
Darkens fry colour - 11What is the target ethylene concentration?10ppm
- 12Ethylene generatorRestrain
- 13Bottled ethyleneBio-fresh
- 14Ethylene reduces shoot growth in onions by....48%
- 15Ethylene easily dissipates, what is the disadvantage of thisNo inhibiting effect once removed from store - evident in potatoes on sale at the moment
