True

False

2. When making pruning cuts which of the statements is generally accepted?

1 point

Pruning cuts should be as close to the parent stem as possible

Smaller cuts or wounds heal faster and require less energy to compartmentalize

Health and vigor play a very small role in pruning practices

The age of a tree is irrelevant in pruning dose

Clear selection

3. The general effects of pruning would be which of these below:

1 point

Loss of food supply and reserve capacity

Changes in plant form

Changes in resource allocation

All of these

Clear selection

4. The Auxin-Cytokinin pathway is an important system affecting root and shoot growth. Which of the following is correct in describing their influence?

1 point

Auxins are manufactured in the shoots to promote root growth

Cytokinins are manufactured in the roots to promote shoot growth

Both of these are correct

A only is correct

Clear selection

5. The effects of excessive pruning includes?

1 point

Increased auxin transport

Increased trunk size

Proliferation of epicormic sprouts

All of these

Clear selection

6. The increase in shoot production as a result of excessive pruning is the result of:

1 point

Plant growth regulators

Poor wound recovery

Excessive fertilization

Cytokinin accumulation

Clear selection

7. It is possible that roots may recede as a result of topping.

1 point

True

False

Clear selection

8. Pruning depletes the tree by:

11. A consequence of removing lots of live green tissue on trees is reduced carbohydrate levels.

1 point

True

False

Clear selection

12. According to research, pruning doses should be observed to reduce stress to the tree which means:

1 point

Pruning dose of 10% or less on mature trees at any one time

Never exceeds 20% of live green tissue on any age tree

Only prune away dead or dying tissue

Pruning should be done only during dormancy to prevent overdosing

Clear selection

13. When considering pruning dose for trees, which of the following are correct?

1 point

Pruning should remove no more living material than is needed to achieve objectives

Consideration should be given to the age of the tree

Health and vigor are important when determining pruning dose

All of these are correct

Clear selection
