|
|
increase water lost by transpiration
|
|
|
Increase microbial growth and development
|
|

Slow down respiration
|
|
|
None of the above

Explanation:
Detailed explanation-1: -To ensure cut flowers last longer, high levels of humidity are required. Ambient air saturation should be around 90%-95%. Also, cut flowers will require adequate rehydration once they’ve been harvested from their source plants.
Detailed explanation-2: -We keep flowers cold to increase their longevity by slowing their use of food reserves they’ve accumulated while growing in the field. Cold temperatures can also reduce the negative effects of ethylene and reduce the growth of microbes.
