What is the recommended angle for recutting fresh flower stems before hydration?
45-degree angle
10-degree angle
90-degree angle
180-degree angle
Cutting stems at a 45-degree angle increases the surface area and prevents the stem base from sitting flush against the container, promoting better water uptake. A steeper or flatter cut can block the xylem vessels and reduce hydration efficiency.
What is the ideal short-term storage temperature for most cut flowers?
30°C (86°F)
20°C (68°F)
10 - 15°C (50 - 59°F)
1 - 4°C (34 - 39°F)
Storing cut flowers at 1 - 4°C slows respiration and water loss, extending vase life. Temperatures above this range accelerate wilting and ethylene production.
Why should flower stems be recut under water before placing them in a vase?
To make stems stronger
To increase water uptake by preventing air entry
To change the flower's color
To remove dirt from the stem
Recutting stems underwater prevents air bubbles from entering the xylem, which can block water uptake. This practice ensures continuous hydration for the flowers.
Which common ingredient in floral preservatives provides energy to cut flowers?
Oil
Nitrogen fertilizer
Acetic acid
Sugar
Sugar serves as an energy source, fueling cellular processes after harvest. Without it, cut flowers deplete stored carbohydrates more quickly, shortening vase life.
What visible sign in vase water indicates bacterial growth?
Floating petals
Blue-tinted water
Cloudy or slimy water
Clear water
Cloudy or slimy water is a hallmark of bacterial proliferation, which can block stems and shorten flower longevity. Regular water changes and preservatives help prevent this issue.
Which water temperature is best for hydrating newly cut roses?
Boiling (100°C)
Lukewarm (27 - 30°C)
Room temperature (20°C)
Ice-cold (0 - 4°C)
Lukewarm water helps dissolve sugars and preservatives more effectively while promoting faster water uptake. Extremely cold or hot water can shock the stems and damage cells.
What pH range is optimal for a commercial floral preservative solution?
8.5 - 9.5 (strongly alkaline)
3.5 - 4.5 (moderately acidic)
5.5 - 6.5 (slightly acidic)
7.0 - 8.0 (neutral to alkaline)
A pH of 3.5 - 4.5 inhibits bacterial growth while allowing sugar uptake. If the solution is too alkaline or too neutral, microbes multiply more readily.
What is the main purpose of adding a small amount of bleach to a floral preservative?
Inhibit bacterial growth
Adjust solution temperature
Provide nutrients
Enhance flower color
Bleach acts as a biocide, reducing bacteria in the vase water. Fewer bacteria mean clearer water and unblocked xylem vessels, leading to longer vase life.
How long is it recommended to condition most cut flowers before arranging?
24 hours
30 minutes
10 minutes
2 hours
A two-hour conditioning period allows flowers to fully hydrate and stabilize after harvest stress. Too short or overly long conditioning can impair the flower's performance in arrangements.
Which type of vase or container is least likely to promote algae growth?
Clear glass
Crystal
Opaque or dark-colored plastic
Transparent acrylic
Opaque or dark containers block light, which algae need to photosynthesize. Clear or transparent materials allow light in and encourage algae proliferation.
Which symptom indicates ethylene sensitivity in cut flowers?
Increased stem rigidity
Petal abscission and premature wilting
Slower water uptake
Enhanced fragrance
Ethylene-sensitive flowers often shed petals and wilt prematurely when exposed to ethylene gas. Recognizing this helps in separating them from ethylene producers.
What relative humidity level is typically recommended for a floral display case?
50 - 60%
10 - 20%
90 - 95%
0 - 5%
High humidity (90 - 95%) minimizes water loss through transpiration, keeping petals and leaves turgid. Lower humidity leads to faster wilting and browning.
Which packaging method best reduces mechanical damage during flower transport?
Individually sleeved and supported by foam
Wrapped only in newspaper
Loose in open crates
Packed flat without padding
Individual sleeves with foam or water tubes cushion stems and reduce rubbing and vibration damage during transit. Loose packaging allows stems and blooms to collide and bruise.
How should flowers be held to avoid water pooling on petals during cleaning sprays?
Heads tilted downward
Submerged completely
Heads tilted upward
Held horizontally
Tilting heads downward lets water run off petals, preventing spotting and fungal growth. Upward or horizontal positions can trap water and damage blooms.
Why is maintaining a continuous cold chain critical for cut flower quality?
Speeds up flower opening
Enhances flower fragrance
Increases stem flexibility
Slows respiration and ethylene production
Keeping flowers consistently cool slows metabolic processes and ethylene synthesis. Temperature fluctuations can cause stress, leading to wilting and shorter vase life.
You observe slimy stem bases and yellowing leaves on a batch of cut tulips. What is the most likely cause?
Bacterial stem blockage
Low humidity stress
Ethylene exposure
Fungal rot from overwatering
Slimy tissue and yellowing are classic signs of bacterial colonization blocking xylem vessels. Proper sanitation and biocide use in the water can prevent this issue.
To maximize vase life of carnations, which combination of preservative ingredients is most effective?
Sugar, bleach, and citric acid
Oil, fertilizer, and salt
Pure water with vinegar
Soap, sugar, and ammonia
Sugar provides nutrition, bleach reduces microbial growth, and citric acid acidifies the solution to optimize uptake. Other combinations either lack nutrients or contain damaging chemicals.
When designing a transport crate for fresh flowers, which factor is most critical to preserve quality?
Maximizing crate weight capacity
Transparent sides for inspection
Shock absorption and adequate airflow
Exterior color for branding
Effective shock absorption protects stems from vibration damage, while airflow prevents heat buildup and humidity spikes. Branding and transparency do not impact flower physiology.
Temperature spikes during shipment can damage cut flowers by:
Increasing stem rigidity
Accelerating respiration and ethylene production
Reducing ethylene sensitivity
Enhancing water uptake
Sudden temperature increases boost metabolic rates and ethylene synthesis, causing rapid wilting and senescence. Consistent cooling is essential to slow these processes.
For long-term storage of daffodils before arrangement, which protocol is best?
Refrigerate at 1 - 4°C with high humidity, away from ethylene producers
Freeze overnight then thaw before use
Store at room temperature with daily water changes
Keep in direct sunlight at 20°C
Refrigeration at 1 - 4°C slows metabolism while high humidity prevents dehydration. Separating from ethylene generators avoids premature aging and flower drop.
