Fruit Ripening

Question 1

It is a dramatic event in the life of a fruit as it transforms a physiologically mature but inedible plant organ into a visually attractive olfactory and taste sensation.

Answer 1

Ripening

Question 2

It is the process where degradation of the flesh allows the mature seed to be released for germination.

Answer 2

Ripening

Question 3

True or False

Some temperate fruits require cool storage to simulate wintering period to activate germination.

Answer 3

True.

Question 4

What does a fruit undergo during ripening?

Answer 4

Changes in cell wall structure
Pigment Accumulation
Flavor and aromatic volatile production
Conversions of starches to sugars

Question 5

The key plant hormone

Answer 5

Ethylene

Question 6

What are the factors that affect the activity of ACC synthase?

Answer 6

The timing of fruit ripening
Senescence
Physical Injuries and chilling injury

Question 7

It is the largest quantitative associated with ripening

Answer 7

Breakdown of carbohydrate = total conversion starch to sugars

Question 8

Do organic acids decline during ripening?

Answer 8

Yes. Because acids are reserve sources of energy to fruit and thus decline during greater metabolic activity during ripening

Question 9

What is the only fruit that experience highest acid level at fully ripe stage?

Answer 9

Banana

Question 10

Is the eating quality determined by flavor and texture or by physiological age?

Answer 10

Flavor and texture
