1. Acid Soil - ANSWER ✓ Soil with a pH of less than 7.0. Agricultural lime is
used to raise the pH and correct a very acid soil condition.
2. Acre - ANSWER ✓ A land containing 43,560 square feet and measuring
approximately 210' x 210' square
3. Asexual - ANSWER ✓ Without sex; refers to reproduction not involving the
fusion of gametes.
4. Auxin - ANSWER ✓ A plant hormone that influences and regulates plant
growth.
5. Balled and Burlapped - ANSWER ✓ Plant prepared for transplanting by
digging them so that the soil adjacent to the roots remains undisturbed; the
ball of earth is then wrapped in burlap or similar mesh fabric.
6. Bare Root - ANSWER ✓ In the winter or early spring, many varieties of
deciduous plants are sold with their roots bare. Dormant plants dug from the
soil have their roots cleaned and trimmed, and are prevented from drying out
until the time they should be planted.
7. Bedding Plants - ANSWER ✓ Refers to small plants sold in flats or packs.
They many be planted in beds, borders or wherever desired.
,8. Biennial - ANSWER ✓ A plant that produces a rosette of leaves the first
year of its life, and sets flowers, fruit and seeds the second year and then
dies. Ex: beet carrot, sweet william.
9. Binomal - ANSWER ✓ A system of naming plants using two names. First
name is the genus and the second the species. Botanical or scientific name.
10.Biodegradable - ANSWER ✓ Any material than can be readily decomposed
in the soil by the action of each microorganisms as bacteria and fungi.
11.Grafting - ANSWER ✓ The process of joining a scion (shoot) into a stock so
that cambium layers grow together and form a union of two plant parts.
12.Ground Cover - ANSWER ✓ Refers to both plants and inert material, used
to cover areas to prevent soil erosion or to discharge the intrusion of
undesirable plants.
13.Growing Medium - ANSWER ✓ Specifically formulated soil substitute
prepared for growing plants.
14.Growing Season - ANSWER ✓ The period of time from the last plant-
killing frost in the spring to the first plant killing frost in the fall.
15.Growth Regulators - ANSWER ✓ Any synthetic or natural organic
compound such as indoleacetic acid, gibberllin, abscission, 2, 4-d,
napthalene acetic acid, etc. which in diluted amounts will promote, inhibit or
modify plant growth practices; also called auxins, plant hormones, and
phytohormones. These hormones regulate leaf drop, root initiation, bud
dormancy, bending of plants in response to light.
16.Guying - ANSWER ✓ Using cable, wire , rope, etc to support a tree, usually
following transplanting.
17.Hardening - ANSWER ✓ A process of slowing plant growth by withholding
water, lowering the temperature, or gradually moving the plants from a
sheltered environment. The process of hardening plants is used to increase
chances for survival at transplanting time.
,18.Hardy Plant - ANSWER ✓ The ability to resist frost damage; a plant which
can be planted before the las killing frost in the spring.
19.Hardiness Zone - ANSWER ✓ Geographic areas representing the average
low winter temperatures of the region; used in horticulture in respect to plant
adaptability.
20.Heading Back - ANSWER ✓ Pruning a branch back to bud or side branch to
make the plant bushier.
21.Heavy Soil - ANSWER ✓ A soil usually difficult to work; clay soils are
considered to be heave soils.
22.Evergreen - ANSWER ✓ A plant which does not lose all its leaves at one
time.
23.Extension Agent - ANSWER ✓ Cooperative Extension Service Agent
located in the county/parish seat of each county/parish of the state to assist
the public with information relating to agriculture, home economics, natural
resources and 4-H.
24.Fertilization - ANSWER ✓ 1) The successful fusion of two sexually
different plant cells to form the embryo of a seed capable of producing a
new plant; 2)The application of fertilizer to soil.
25.Fertilizer - ANSWER ✓ A material which provides one or more mineral
nutrients in forms which can be used by growing plants. The term generally
refers to materials of organic or inorganic origin that are known to increase
nitrogen, phosphate, and potassium when added to soil or dissolved in water.
26.Flower - ANSWER ✓ Usually a symmetrical form of colorful growth with
the primary purpose of producing seed for plant reproduction.
27.Foliage Plant - ANSWER ✓ Plants grown especially for the beauty of it
foliage as contrasted to those plants grown for flowers or fruit.
28.Frond - ANSWER ✓ The leaf of a palm tree or fern.
, 29.Frost - ANSWER ✓ Temperature below the dew point, causing freezing
condition and a covering of minute ice particle on exposed objects.
30.Fumigant - ANSWER ✓ A chemical used in the form of a volatile liquid or
gas to kill insects, nematodes, funi, bacteria, seeds, roots, rhizomes, or entire
plants; usually released within an enclosure or in the soil.
31.Fumigation - ANSWER ✓ Applying chemicals or gases to control insects
within an enclosed area or under a plastic cover.
32.Fungicide - ANSWER ✓ A chemical material used to retard or prevent the
growth of fungi.
33.What is the '1/3 rule' for mowing frequency? - ANSWER ✓ No more than
1/3 of the leaf blade should be removed while mowing
34.Should grass clippings be returned or collected during mowing? - ANSWER
✓ It depends on the site's needs. If clipped grass is functionally or
aesthetically undesirable, yes. However, turf with removed clippings will
need more fertilizer. Returned clippings contribute approx 5%-10% of thatch
35.When and why do lawns need dethatching? - ANSWER ✓ Thatch is the
intermingled layer of living and dead plant material on the soil service.
Thatch up to 0.5" is desirable for insulation and erosion purposes. Deep
thatch causes mechanical, biological, and environmental stresses (insects,
spongey thatch compresses under a mower and cuts too short, thatch is
difficult to re-wet). Dethatch when it is deeper than 0.5".
36.Discuss the life cycles of the following turfgrass weed groups: winter
annuals, summer annuals, perennials - ANSWER ✓ Annual a weed that
completes its entire life cycle in one growing season. Germinates, matures,
produces seed, and dies.
