Answer to Question 1
Treating flowers with silver thiosulphate (trade name Floralife) blocks the ethylene
receptor, thereby stopping ethylene's capability to function as a plant hormone.
Placing horticultural commodities in hypobaric storage keeps the commodity under
vacuum and thereby does not enable ethylene to stay in contact with the commodity,
which in turn stops ethylene's capability to act.
Treating horticultural commodities with levels of CO2 greater than 2 percent
reduces the capability of the ethylene receptor to accept ethylene, which in turn
blocks ethylene action.
Genetically engineering plants that have a modified ethylene receptor that does not
accept ethylene blocks ethylene's action.
Answer to Question 2
Decreasing the storage temperature
Decreasing the oxygen levels to less than 8 percent
Treating with inhibitors such as aminoethoxyvinylgly cine (AVG), aminooxyacetic
acid (AOA), or cobalt chloride
Using antisense technology, more specifically, inserting the antisense constructs for
ACC synthase and/or ACC oxidase
