31
Q

Q. Hybrid vines are usually used as?

A

Q

Q. During one of Phylloxera’s phases it lives underground feeding on?

A

A. The vine’s roots.

36
Q

Q. Phylloxera kills vines by?

A

A. Infections through feeding wounds.

37
Q

Q. What natural protection does Vitis Vinifera have to Phylloxera?

A

A. None

38
Q

Q. What natural protection do American vines have to Phylloxera?

A

A. They release sap, clogging Phylloxera’s mouth.

Sap protects the feeding wounds from secondary infection.

39
Q

Q. When Phylloxera broke out in Europe in the nineteenth century, what two methods were used to manage it?

A

A. Planting American vines or hybrids.

Grafting American root stock onto Vitis Vinifera vines.

40
Q

Q. Grafting is now preferred to planting American vines or hybrids. Give three reasons why.

A

A. American vines and hybrids often have unattractive flavours.

Grafting allows v. vinifera fruit with Phylloxera resistant American roots.

Root stocks can be chosen for the location whether it is pest resistance (nematodes) or drought tolerance.

41
Q

Q. In relation to grape vines, what is grafting?

A

A. A technique for fusing rootstocks to Vitis Vinifera.

42
Q

Q. What type of grafting is this: A short section of V. Vinifera cane is joined to another rootstock using a machine in a nursery.

A

A. Bench grafting

43
Q

Q. What type of grafting is this: In the vineyard a vine is cut back to its trunk and a new bud or cutting is grafted on?

A

A. Head grafting

44
Q

Q. What are the advantages of head grafting over bench grafting?

A

A. Quicker, 1 year vs 3 years for first grapes.

Cheaper

The new variety has an established root system.

45
Q

Q. Which is the best method of grafting for a new vineyard?

A

A. Bench grafting

46
Q

Q. What are the four sections of the vine?

A
