HORT 201 Exam #3

True

Proper harvesting techniques help minimize mechanical damage to produce

False

Non-climacteric fruits rely on ethylene for ripening after harvest.

False

Late harvesting generally results in firmer fruits

False

Heading cuts remove an entire branch from its base

True

The primary role of postharvest storage is to extend shelf life

True

Modified atmosphere packaging is a method used to prolong fruit freshness

False

Open-center training systems are commonly used for apple trees

True

Non-climacteric fruits should generally be harvested at full ripeness

False

Mechanical damage during handling has no impact on post harvest quality.

True

Chemical pruning involves the use of chemicals to control plant growth.

False

Pruning should always be done in early spring

False

The central leader system is commonly used in grapevine training

True

Trellis systems are used primarily for growing grapes

True

Over-pruning can weaken plants and reduce fruit yield

True

Sugar content (Brix) is an important indicator of fruit quality

True

All crops should be harvested at the same maturity stage for optimal quality

False

Fruit trees do not require pruning after they reach maturity

True

Photosynthesis plays a role in source-sink relations by supplying energy

True

Proper pruning improves light penetration in the canopy

False

Source-sink relations refer to the movement of water in the plant

False

All fruits should be stored at the same temperature postharvest

True

Pruning helps improve plant structure, health, and productivity

True

Late pruning can delay fruit ripening

False

Harvest timing does not affect consumer acceptance

False

In source-sink relations, the sink is always located at the roots

True

Training systems help guide plant growth for better light exposure and airflow

True

Dormant pruning is typically performed during winter

True

Excessive pruning can lead to increased vegetative growth at the expense of fruit production

True

Bananas and tomatoes are examples of climacteric fruits

True

Removing excess fruit can improve the size and quality of the remaining fruits

False

Summer pruning is done to encourage vegetative growth.

True

Climacteric fruits continue to ripen after harvest

True

Pruning tools should be sanitized to prevent disease spread

True

Pruning and training systems vary based on plant species and growth habits

True

Rejuvenation pruning is used to restore old or declining plants

False

Thinning cuts encourage lateral branch growth

False

Pruning has no impact on fruit quality

True

Removing excess fruit can improve the size and quality of the remaining fruits

True

The central leader system promotes strong vertical growth in trees

True

Leaves serve as the primary source in source-sink relations
