Nowadays, most grape varieties are grown and propagated using seeds. *

1 point

True

False

Which of the following statement is true? *

1 point

Vitis Vinifera is the main American species used to make wine for several thousand of years

Vitis Vinifera is resistant to Phylloxera.

American vines are widely used to produce rootstock for Vitis vinifera.

Vitis Vinifera is rarely used to produce grapes for winemaking because the fruit produced are widely considered unattractive.

Which of the following statement is false? *

1 point

Although individual vines of a grape variety are genetically identical, mutation can be observed.

Clonal selection refers to the propagation of a variety which can be traced back to the same plant

Cuttings used for propagation are usually grafted on Philloxera-resistant rootstocks

Pinot Blanc and Pinot Gris are actually mutation of Pinot Noir and considered as new varieties.

None of the statements above are false

Why would a grower chose to propagate a clone rather than another? (check all that apply) *

1 point

Because the chosen clone yields better quality of fruit

Because the chosen clone will yield seeds that can later be propagated to maintain identical DNA material and characteristics

Because the chosen clone yields seedless berries

Because the chosen clone has better disease resistance

Required

Which of the following is a "crossing"? *

1 point

A new variety created from two parents of the same species such as Müller-Thurgau

A new variety created from parents of different species such as Vidal

A new variety of vitis vinifera grafted upon a non-vinifera rootstock

A new variety of American origin grafted upon vitis vinifera rootstock

About Phylloxera, which of the following statement is false? *

1 point

Phylloxera is an insect that feeds on the roots of the vine, leaving wounds from which vitis vinifera can't recover.

Today, Phylloxera is a problem nearly in every vineyard area except Chile, some parts of Argentina and South Australia.

American vines are resistant to Philloxera and therefore used as rootstock for vitis vinifera

Phylloxera destroyed the vineyards of the American continent during the 14th century

1 point

A. Heaters and or wind machines

B. Vineyard design (high training or/ and on slope)

C. Sprinklers (spraying water onto the vines, causes water to freeze and releasee heat to the plant tissue, which protect buds and shoots

D. Answer A, B and C

E. Answer A and B only

Which of the following statement is false concerning water in a vineyard? *

1 point

A vine requires water for photosynthesis and to swell its grapes during ripening

The amount of water required by a vine depends on temperature

Controlled water stress can be beneficial for a vine as it concentrates on grape ripening rather than further shoot growth

Water stress causes canopy to grow too large and promotes shading on fruits and slows ripening.

Which of the following is the most advanced and expensive form of irrigation? *

1 point

A. Sprinklers

B. Flood irrigation

C. Drip Irrigation

D. Answers A and B

Which statement is true regarding "weather" and "climate"? *

1 point

Weather is defined as the annual pattern of temperature, sunlight and rainfall averaged out over several years.

Weather does not change from one year to the next, though it can alter over a period of decades.

Climate is the annual variation that happens relative to the climatic average.

In some regions such as Central Valley in California, weather is more predictable than Bordeaux where weather variation can affect the quality of every vintage

Which of the following statement is false about soil and nutrients? *

1 point

The most important nutrients are Nitrogen, Phosphorus and Potassium

Which statement is false concerning vine pruning? *

1 point

Vine pruning is the removal of unwanted leaves, canes and permanent wood to produce a desired shape, size and yield.

Spur pruning has occurred when spurs (short sections of one-year-old wood) are left on the vine either on the head or the arms.

Replacement Cane pruning has occurs when canes (long sections of one-year-old wood) are retained horizontally on the vine and is tied to a wire

Single Guyot and Double Guyot are examples of spur pruning techniques
