Worksheet time: 14mins
Plants Absorb what type of light?
Green
White
Radiant
Heated
Which one isn't an effect that temperature plays in a plant?
Productivity
Poor Production of Fruit
Prevent Fruit Development
Plant Longevity
When a plant expends more energy than it creates during the day what happens to the plant?
Stunted Growth and Low Yields
Accelerated Growth and Low Yields
Stunted Growth and High Yields
Accelerated Growth and Higher Yields
what is used to factor a hardening Zone area?
Light Intensity Ranges
Min Average Annual Rainfall
Average min Daily Light
Average min Annual Temp
Why and How do we utilize the GDD information?
These are estimated growth and development temperatures that don't fall below 50 or above 86 with and average set for growing period.
This information is used to estimate the growth and development of plants and insects during the growing season.
What are the two common areas that plants are divided up into?
Fall-Season & Spring -Season
Winter-Season & Summer-Season
Cool-Season & Warm-Season
Rainy-Season & Dry-Season
This type of plant will NOT adapt to the cooling weather.
Winter Hardy
Perennial
Annual
Summer Delicate
How do you utilize the Growing Degree Days (GDD) infromation?
PLANTS are ONLY dependent on the amount of heat present in or around the organism and this can factor into several management practices.
PLANTS and ANIMALS are dependent on the amount of heat present in or around the organism and this can factor into several management practices
How do plants use sunlight?
They reflect the light rays of the white light much like a radio takes in sound waves and turns them into sound. White light chemically is changed in the reaction center of the plant.
They absorb the light rays of the white light, much like a radio take sound waves and turns them into music. They absorb Red & Blue the most while they reflect Green.
How do you increase or decrease the light intensity in a greenhouse?
Place plants closer to the light source to DECREASE the intensity of the light.
Place plants closer to the light sources to INCREASE the intensity of the light.
You can't increase the intensity only the duration of light in a greenhouse.
What is photomorphogenesis- What is this process responsible for?
Process of plant producing fruit and seeds
Process of plant producing sugars, proteins and minerals and minerals for growth and development.
Process of putting plants through a cold phase to bring on flower.
What does the quality of light refer to?
How bright the light is
How intense the light is and the heat given
The color and wavelength reaching the plant
What does Red & Blue light influence in plants?
Root Growth
Flowering
Leaf Growth
Stem Elongation
What are the three areas we need to consider when using artificial light? (Choose what applies)
Intensity
Duration
Quality
Heat Output
Choose which plants are warm season plants:
Cotton
Soybeans
Cabbage
Carrots
What are two factors that play into the plant's survival during dormant stages?
How long the cold lasts
Quality of Light
Age of Plant
When we put plants through the hardening process we are allowing plants to become more resistant to the effects of cold temperatures.
True
False
Cabbage and Barley fall under Cool Season crops.
True
False
Plants that make it through the dormant stage of winter can still be harmed/killed if they reach temperatures below their tolerated temperatures.
True
False
When plants are under temperature stress the plant's photosynthesis process speeds up in warm temps and slows down during cooler temps.
True
Flase
If you mix Fluorescent and incandescent lights you will want to have 4 watts of Fluorescents to 1 watt of Incandescent.
True
Flase
The Stems, Flowers and Roots are the part of the plant doesn't always make through the dormant stage.
True
False
Northern exposure to light is about 60% of the light intensity while Western and Eastern Give about 20% of what Southern offers.
True
False
When the nights are too warm plants tend to increase photosynthesis production and create more food during the night time.
True
False
Why is it important to know GDD for insects?
Help us improve managment practices
This isn't important for plant production
Helps us decided when to start planting
Which statement is TRUE about development of a plant when the temperature increases from ideal temperatures?
Too Warm increases growth
Too Warm growth slows
Too Warm stops growth
What is meant by Optimal temperature for germination?
Tells us the best temperatures for seed development
Tells us best temperatures of fruit development
Tells us best temperatures for root growth
