The climatic conditions that are needed for carnations to be grown successfully as a cut flower include?

• Low light intensity, mild climate requiring minimal amount of protection, uniform temperature and day length
• High light intensity, mild climate requiring minimal amount of protection, and cold nights and hot days
• High light intensity, mild climate requiring minimal amount of protection, uniform temperature and day length
• Low light intensity, mild climate requiring minimal amount of protection, and short days

In growing chrysanthemums as cut flowers the plant requires which of the following conditions to maintain a vegetative state of growth?

• Day length at less than 9.5 hours growing at 60 degrees
• Day length between 11 and 12 hours growing at 80 degrees
• Day length at 10.5 hours growing at 60 degrees
• Day length greater than 14.5 hours growing at 60 degrees

The advantages of an ebb and flood irrigation system in the greenhouse are:

• Labor savings
• Reduced water and nutrient use
• Lower pesticide use
• All of the above

Which of the following is not a plant hormone that can be used as a plant growth regulator

• ethylene
• anthocyanin
• abscisic acid
• gibberellin

The best root medium pH for a majority of spring bedding plants, but not including petunias or geraniums, is:

• 4.5 to 5.5
• 5.5 to 6.5
• 6.5 to 7.5
• 7.5 to 8.5

In grafting, such as for grafted tomato transplants,

• the scion is the top part of the graft and the rootstock is the lower part
• the rootstock is the top part of the grant and the scion is the lower part
• the scion often imparts disease resistance to the grafted plant
• the rootstock often provides desirable fruiting characteristics

The pistil is

• the female part of the flower
• the male part of the flower
• contains both the male and female parts of a flower
• becomes seeds

The pH of the root medium indicates to a greenhouse grower its

• volumetric water content
• salt ions dissolved in water
• hydrogen ion concentration
• organic matter content

On a financial planning sheet, the costs of the plant materials (i.e. purchase cost of seeds, cuttings, bulbs, or other plant propagule) would be examples of:

• wholesale costs
• overhead costs
• fixed costs
• direct costs

• (i) 6-inches, (ii) 6-inches
• (i) 6-inches, (ii) 4.5-inches
