18 Questions
What is the primary role of ethylene in fruit ripening?
To coordinate genes for complex reactions involved in ripening
How do climacteric fruits respond to increased ethylene concentration?
They are less affected by ethylene concentration
What is the effect of supplementing ethylene on the ripening of non-climacteric fruits?
It has a significant influence on the ripening process
What is the purpose of using electric equipment instead of gas equipment in fruit harvesting?
To avoid excessive production of ethylene gas
What is the characteristic of ethylene gas?
It has a faint, sweetish smell
At what temperature range do ripening rooms typically operate?
18 to 25°C
What is the term for the production of CO2 in a plant?
Respiration
At which stage of fruit development does the respiration rate reach a peak?
Soon after harvest
What is the term for the rapid increase in respiratory rate in fruits?
Climacteric
What happens to the respiration rate per unit weight of a product as it matures?
It declines
Why is it necessary to remove heat from fruits during transportation?
To prevent quality deterioration
What is the classification of fruits based on their respiratory activity?
Climacteric and non-climacteric
What is the stage of development that occurs after growth and before senescence?
Maturation
What marks the completion of fruit development and the commencement of senescence?
Ripening
What is the stage of development when a plant part will continue to develop even if detached?
Physiological maturity
What is the stage of development when a plant part possesses the necessary characteristics for use by consumers?
Horticultural maturity
What is the process that begins during the later stages of maturation and is the first stage of senescence?
Ripening
What is the process where growth ceases and breakdown begins?
Senescence
Learn about the physiological development of fruits and vegetables, including cell division, growth, maturation, ripening, and senescence. Understand the different stages of fruit and vegetable development and how they affect quality.
