What is the definition of fruit development?
Click to flip
Fruit development is the process by which a fruit forms and matures from the ovary after fertilization, encompassing stages like fruit set, growth, and ripening.
Click to flip
What role does auxin play in fruit development?
Click to flip
Auxin is a plant hormone that influences cell growth and division, crucial for the enlargement of the fruit and the early stages of ovary development after fertilization.
Click to flip
How does pollination affect fruit development?
Click to flip
Pollination leads to fertilization, which triggers the hormonal changes necessary for the ovary to develop into fruit, including the cessation of floral development.
Click to flip
Describe the fruit set stage in fruit development.
Click to flip
The fruit set stage is when the fertilized ovary begins to grow and develop into a fruit, marking the transition from the flower phase to the fruit-bearing phase.
Click to flip
What is the importance of ethylene in fruit ripening?
Click to flip
Ethylene is a plant hormone vital for initiating the ripening process in many fruits, leading to changes in color, texture, and taste.
Click to flip
What is parthenocarpy in fruit development?
Click to flip
Parthenocarpy is the development of fruit without fertilization, resulting in seedless fruits, commonly seen in varieties of bananas and grapes.
Click to flip
How do environmental factors affect fruit development?
Click to flip
Environmental conditions such as temperature, light, water availability, and nutrient supply significantly influence the rate and success of fruit development.
Click to flip
What is the difference between climacteric and non-climacteric fruits?
Click to flip
Climacteric fruits continue to ripen after being harvested due to ethylene production, whereas non-climacteric fruits do not.
Click to flip
Can fruit development occur without pollination?
Click to flip
Yes, through processes like parthenocarpy, fruits can develop without pollination, resulting in seedless fruits.
Click to flip
What role do gibberellins play in fruit development?
Click to flip
Gibberellins are plant hormones that promote fruit growth by enhancing cell division and elongation, especially during the early stages of development.
Click to flip
How does nutrient supply affect the quality of developing fruit?
Click to flip
Adequate nutrient supply, particularly nitrogen, potassium, and phosphorus, is essential for high-quality fruit development, affecting taste, size, and nutritional value.
Click to flip
What stage of fruit development involves sugar accumulation?
Click to flip
The ripening stage involves sugar accumulation, where starches convert into sugars, contributing to the fruit’s sweetness.
Click to flip
What are the primary stages of fruit development?
Click to flip
The primary stages of fruit development are fruit set, growth, and ripening.
Click to flip
Why is cross-pollination often beneficial in fruit development?
Click to flip
Cross-pollination introduces genetic diversity, often leading to better-quality fruits with enhanced resilience and disease resistance.
Click to flip
How does water supply during fruit development influence fruit size?
Click to flip
Consistent water supply is crucial for optimal fruit size, as water stress can limit cell expansion and reduce overall fruit growth.
