Question

Which country developed Tatura Trellis system of grape ?

• A. U.S.A.
• B. Italy
• C. Australia
• D. France

Hint:

Trellis Systems Summary:
- Tatura Trellis: Australia (V-shaped architecture for high light interception).
- Bower Arbour (Pandal) System: Widely used in India for commercial grape production.
- Kniffin System: 4-cane training on 2 wires.

Answer 1

The Correct Option is C

Step 1: Understanding the Question:
The question asks for the origiting country of the 'Tatura Trellis' training system, which is a high-density canopy training system widely adopted in commercial fruit orchards and vineyards.

Step 2: Key Concepts and Design Features:

• Origin: Developed during the 1970s at the Tatura Research Institute located in Victoria, Australia.

• Canopy Architecture: The system utilizes a 'V'-shaped or 'Y'-shaped trellis structure where two arms extend outwards at an angle of $60^\circ$ from the horizontal axis.

• Light Interception: By directing branches onto angled trellis frames, light penetration into the inner canopy is maximized, promoting high photosynthetic efficiency.

• Crop Applicability: Origilly engineered for stone fruits like peaches, it was subsequently adapted for high-density viticulture (grapes) and apple orchards.

Step 3: Detailed Explation:

• In traditiol vineyard training systems, dense foliage creates interl canopy shading, leading to poor bud fertility and diminished fruit quality.

• The Tatura Trellis system splits the canopy into two distinct, thin fruiting walls tilted outward.

• This structural design dramatically increases solar light interception per unit land area, improving sugar accumulation, skin color development, and overall yield per hectare.

• Because it was conceived and perfected at the Tatura Research Station in Victoria, Australia, credit for its innovation belongs to Australia.

Step 4: Fil Answer:
The Tatura Trellis system was developed in Australia. Therefore, option (C) is the correct choice.
