What techniques can be used to make Vitis Vinifera resistant to
Phylloxera?—Ans: Grafting of rootstock
What is a shoot?—Ans: The new growth a vine produces each
year.
Where can you find "nodes"?—Ans: Along the length of each
shoot
What is contained at each node?—Ans: A leaf and a flower OR
leaf and a tendril
Where do buds form?—Ans: Where leaf stems join the shoot.
What are the grapevine's "engine"?—Ans: The leaves
© 2025 Assignment Expert
What are leaves responsible for? Explain.—Ans: Photosynthesis,
which is the process by which plants use chlorophyll and energy to
convert water and CO2 into sugar glucose and oxygen.
What are the three primary uses of the glucose produced in
Guru01 - Stuvia
photosynthesis?—Ans: 1) Combining small glucose molecules into
larger carbohydrates creating the building blocks for all structures
2) Energy stored in glucose can be released when needed for
other living processes
3) Concentrated in the fruit, to make them attractive to the
animals, needed to propagate seeds
What are tendrils?—Ans: Structure vines used to grip a supporting
structure
What do tendrils do?—Ans: Once they sense a supporting
structure, they wind tightly around it to keep the shoot upright
What is the importance of flowers on a grapevine?—Ans: It is the
plant's reproductive organ
What type of reproductive organs do flowers on the grapevine
contain?—Ans: Both female and male
What are inflorescences?—Ans: Bunches of flowers

How does pollination of the grapevine happen?—Ans: Wind or
animals
What is an embryonic shoot?—Ans: A bud found between the
leaf and shoot
Where does a bud mature?—Ans: Inside their casing during the
growing season
What does a bud look like at the end of the growing season?—
Ans: A miniature version of all the structures that will become the
shoot, leaves, flowers, and tendrils in the following year
What is one year old wood? When is it formed?—Ans: Shoots that
have turned woody during the winter after they have grown
© 2025 Assignment Expert
Why is it important to manage the one year old wood?—Ans:
Because vines will normally only produce fruit on shoots that grow
from buds that developed the previous year
Guru01 - Stuvia
How is one year old wood cared for?—Ans: Every winter the vine
is pruned
What is a cane?—Ans: Long one year old wood containing 8-15
buds
What is a spur?—Ans: Short one year old wood containing 2-3
buds
What is permanent wood?—Ans: Wood which is more than 1 year
old
How is the amount of permanent wood restricted in the
vineyard?—Ans: Pruning
What is permanent wood made up of?—Ans: Trunk and arms of
the vine
What are cordons?—Ans: The arms of the vine
Where does the vine store some of its carbohydrate reserves in the
winter?—Ans: Permanent Wood
What are the carbohydrate reserves used for?—Ans: To fuel initial
growth until leaves can start supplying carbohydrates
, 4
For Expert help and assignment solutions, +254707240657
Where are carbohydrate reserves especially important?—Ans:
Cool climates where there is a slow start to the growing season
What is the purpose of the roots?—Ans: Absorb water and
nutrients from the soil, anchor the vine, and store carbohydrates to
allow the vine to survive the winter
What are most Vitis Vinifera grated onto? Why?—Ans: Root
systems from other species because they are not resistant to
phylloxera
What has to happen for a population of grapevines to belong to
the same grape variety?—Ans: Every plant must follow a line of
cuttings taken from cuttings back to the same, single, original
© 2025 Assignment Expert
'parent' plant
How are two grapevines known to be of different grape
varieties?—Ans: If when their ancestry is traced back to cuttings
from a seed, two different seedlings are found

What are the 6 principal differences in the Vitis Vinifera grape
varieties?—Ans: 1) Grape Color
2) Grape Composition
3) Grape Flavor
4) How well they ripen in different environments
5) Tolerance to pests and diseases
6) Yields they can produce
What is another term for grape variety?—Ans: Vine variety
What is another term for variety?—Ans: Cultivar or Varietal
What are the two primary routes for variation within a grapevine
species?—Ans: Sexual reproduction and mutations
How does a new variety establish using sexual reproduction?—
Ans: A flower is pollinated and grows into a grape with seeds. If
the seed is planted, it will become a new variety. Every seedling is
in theory a new variety.
