The buds, flowers, and tender new growth are pitted or stunted. Tiny insects are often invisible. A sticky fluid secreted by the insects provides a medium for growth of sooty mold and attracts ants. The most likely candidates are:Spider mitesAphidsMealybugsSnails and slugs __________ induces adventitious roots to form on stems while they are still attached to the parent plant.DivisionBuddingLayeringGrafting African violets are typically propagated by:Leaf cuttingsStem cuttingsAir layeringRoot division A component of greenhouse root media consisting of siliceous volcanic rock, crushed, and heated to 1800 degrees F is:VermiculiteCrushed stonePerliteSand In order to create successful arrangements, one must understand the range of acceptable color combinations called color schemes. One of the following is not among this frequently used color schemes:MonochromaticAnalogousTriadQuadraplex A hue with white added is termed a:TintToneChromaAccent Light energy, carbon dioxide and water enter into the process of photosynthesis, through which:Respiration resultsCarbohydrates are formedChlorophyll is formedAmino acids are formedFloral preservatives function to:Provide sugarSupply a bactericideAcidify the solutionAll of the aboveThese insects are identified by the cottony material found on stems and along leaf veins:AphidsMealybugsSpider mitesWhitefliesWhere in a floral arrangement should light-colored flowers be placed?near the top of the flower arrangement.near the center of the flower arrangement.towards the bottom of the flower arrangement.light-colored flowers should not be used as a rule.The reason for putting irregularly shaped stones, or broken pieces of pottery into the bottom of a pot containing flowering plants is:they let air into the pot from the bottomthey allow the roots to grow out the bottom of the potit helps the soil to drain after being wateredit’s just an old tradition passed down from person to person and does not help the plants.

Root growth, stem and leaf beauty. Weeds, insects, diseases and other organisms that can damage crops. Tree growth and plant pollution. __________ ____________ regulation is defined as any chemical or process used to produce a specific type of growth response, such as inhibition or internode elongation or root development. Plant growthAbscisic acidTissue cultureRoot developmentThe advantage of a good artificial media are: It is sterile and uniform in content It is lighter in weight and therefore easier to handle and ship than natural soil It has good drainage and moisture holding ability All of the above The binomial name for a plant includes the: Order and family Genus and species Class and subclass Division and class A horticulture term meaning to be covered with short soft hairs:Variegated Punctate Ratoon PubescentBaby’s Breath is an example of a ______________flower.mass filler form foliageThe Florist wire is used in corsage and bout construction to: Hold the flowers in correct position Make arranging easier Prevent the flower heads from breaking off the stems All of the above Why is it important not to keep fruit baskets in the same cooler with fresh flowers?because fruit flies eat flower petalsbecause ethylene gas from the fruit with cause the flowers to age quicklybecause bananas and apples give off an odor that will be transmitted to the flowersbecause florists shouldn't sell fruit; that's the job of the grocery store.The size relationship of a floral arrangement with its surroundings is:HarmonyRhythmScaleBalanceA leaf with parallel venation:Has leafletsIs a monocotHas crossing veinsIs a compound leafThe showy red, pink, or white portion of the poinsettia are:FlowersBractsPetalsSepalsThe typical length of florist wire is:12 inches18 inches20 inches24 inchesSecondary macro-nutrients are:Calcium, magnesium, and sulfurZinc, molybdenum, and copperNitrogen, phosphorus, and potashCalcium, zinc, and potashWhen using the ratio markup method, a 5 to 1 item with the total wholesale value of the material costing $12.00 would retail for:$30.00$120.00$60.00$45.00 The flower part that contains the pollen is the:OvaryFilamentAntherCorollaThe optimum pH range for azaleas is:6.5 to 7.59.0 to 10.04.5 to 5.57.0 to 8.0The natural process by which plants grow in the direction of the strongest light source is called:PhotoperiodismPhotomorphogenesisGeotropismPhototropismFor optimum germination, seeds of nearly all bedding plants require a propagation medium temperature of:75 to 85 degrees55 to 65 degrees45 to 55 degrees35 to 45 degreesCorsages are most commonly worm on the ___________ ____________.Left shoulder Right shoulderLeft wristD.
