BLINN COLLEGE HORTICULTURE EXAM SOLVED
CORRECTLY #19
Scarification - correct answer breaking or softening a seed coat to allow absorption of
moisture
Why do some seeds need to be soaked or scratched - correct answer scratching the
seeds will help break down the seed coat.
Bisexual reproduction in plants - correct answer plants that are the same sex
Hybrids - correct answer The offspring of two different varieties
Indirect seeding (transplanting) - correct answer planting seeds indoors and growing
seedlings prior to being transplanted to a larger container or to a permanent location
outdoors.
Vermiculture - correct answer the raising and production of earthworms and their by-
products.
Hardening off - correct answer Process of moving plants outdoors for a portion of the
day to gradually introduce them to the direct sunlight, dry air, and cold nights.
Tissue culture - correct answer Technique for growing pieces of living tissue in artificial
media
Temperature soil is sterilized at - correct answer 180 degrees
Pelleted - correct answer refers to seeds that are coated with an organic clay-based
compound to create a large seed that will be easier to sow
Seed coat - correct answer A tough outer covering of a seed, formed from the outer
coat of an ovule.
Endosperm - correct answer food-rich tissue that nourishes a seedling as it grows
Embryo - correct answer developing stage of a multicellular organism
Construction sand - correct answer granite rock, gneiss, or limestone.
Sphangnum Moss - correct answer seed starting, as a planting medium for orchids, as a
potting soil amendment, for lining baskets, or for other art projects. It has a neutral ph
level and is great for retaining moisture in the soil, even when dried.
, Perilite - correct answer Perlite is a naturally occurring mineral that is added to garden
soil to improve aeration, water retention and drainage. It looks like small, white
Styrofoam balls and is commonly found in potting soil and seed-starting mixes.
How to Identify the top and bottom of a cutting - correct answer top cutting is the most
basic, and requires just one snip. By separating the top of the stem from the bottom,
cutting on the internode, you remove the plant's terminal bud, the growth point at the top
of the stem. You can see this growth point as a pointy bump forming on the petiole of
the newest leaf.
The best time of day to take a cutting - correct answer early morning because plants
have more moisture.
Transpiration - correct answer Evaporation of water from the leaves of a plant
Meristem culture - correct answer A method for the asexual propagation of plants, in
which pieces of shoot apical meristem are cultured to produce plantlets.
Tissue culture, what parts of plant are used for this - correct answer Plants important to
developing countries that have been grown in tissue culture are oil palm, plantain, pine,
banana, date, eggplant, jojoba, pineapple, rubber tree, cassava, yam, sweet potato, and
tomato.
Callus formation - correct answer mass of tissue that forms at a fracture site and
connects the broken ends of the bone
Humidity level for new cuttings - correct answer 80 to 95 percent.
Juvenile effect - correct answer is important as it affects when a plant can become
reproductive. ... Having completed the juvenile phase, plants may be described as "ripe
to flower.
Softwood cutting locations - correct answer Softwood cuttings should be approximately
4 to 6 inches long. Pinch off the leaves on the lower half of the cutting. Also remove any
flowers. Make a fresh cut just below the point where one or two leaves are attached to
the stem (node) and then dip the base (cut end) of the cutting in the root-promoting
compound.
Asexual - correct answer Process by which a single parent reproduces by itself
Clone - correct answer An organism that is genetically identical to the organism from
which it was produced
Fungicide - correct answer substance that kills fungi or inhibits their growth
