6
Protective

• Epidermis

7
Support Conductive

• Xylem (tracheid cells and trachea)
• Phloem (sieve tubes)

8
Parts of the Vine

• These parts may be classified into two groups by
  the work they perform
• Those that carry on vegetative activity
• Those that produce seed or fruit

9
Root system

• 2-5 feet you will find the bulk of the roots.
• Lateral growth of roots is rarely restricted by
  natural conditions.
• Tens of thousands of rootlets are produced by a
  vine of moderate size.
• Absorption zone is the region through which
  most of the water and mineral nutrients pass in
  entering the vine.

10
Shoot system

• Shoot
• Growing tip
• Buds
• Leaf buds
• Axillary buds
• Leaf
• Blade or lamina
• Tendrils

• Lateral shoots
• Arms
• Trunk
• Spur
• Cane

11
Shoot

• Current years growth that arises from the bud.

12
Growing tip

• At the end of the shoot is the growing tip, 4-8
  inches long, in which new cells are being formed
  by division and in which elongation is taking
  place.

13
Buds

• Normally develops at each node just above the
  leaf, in the leaf axil. A bud of a vine usually
  consists of three partially developed shoots,
  with rudimentary leaves or both rudimentary
  leaves and flower clusters.

14
Leaf buds

• Is a rudimentary sterile shoot. It will elongate
  into a shoot that bears only leaves and tendrils.

15
Axillary buds

• Usually describes the bud joint between the leaf
  stem and the shoot.

16
Leaf

• Is an expanded, lateral outgrowth of a shoot,
  arising at a node, and having a bud in its axil.

17
Blade or lamina

• Is the expanded or broad, flat part of the leaf.

18
Tendrils

• Give physical support to the primary shoots by
  coiling themselves around anything they come in
  contact with.
• from the point of structure they are looked at
  as a cluster.

19
Lateral shoots

• Form the canes.

20
Arms

• The permanent divisions of the vine, arising from
  or along the top of the trunk.
• They bear spurs or canes which are retained for
  next years production and shoots for this years
  production.

21
Trunk

• The permanent upward stem.
• It connects the roots to the arms.

22
Spur

• Short bearing unit retained during pruning.

23
Cane

• Long bearing unit retained during pruning.
