What is meant by Stenospermocarpy?

Definition of stenospermocarpy : the production of abortive incompletely developed seeds (as in a seedless grape) with normal development of the berry — compare parthenocarpy.

What is Stenospermocarpy parthenocarpy?

Stenospermocarpy is the biological mechanism that produces parthenocarpy (seedlessness) in some fruits, notably many table grapes. Before the tiny embryo aborts, it is removed from the developing fruit and grown in tissue culture until it is large enough to survive on its own.

What are the Parthenocarpic fruits?

Pineapple, banana, cucumber, grape, watermelon, orange, grapefruit, pear, fig are some examples of Parthenocarpy. These develop without fertilization and are often seedless.

What vegetables are Parthenocarpic?

The parthenocarpic character can be found in most of the common cucumber types (Figure 2), i.e. picking, slicer, long and mini cucumbers. It also exists in summer squashes. Green zucchinis are more likely to carry the parthenocarpic character, varieties include Partenon, Dunja etc.

Why is banana fruit seedless?

Bananas are seedless because the parent banana tree is triploid (3X chromosome sets) even though pollination is normal. Parthenocarpy, fruit development without pollen fertilization and seed set, can result in seedless fruits such as grapes, squash (Cucurbita pepo ), and eggplants (Solanum melongena ).

What is induced Parthenocarpy?

In botany and horticulture, parthenocarpy is the natural or artificially induced production of fruit without fertilisation of ovules, which makes the fruit seedless. Stenospermocarpy may also produce apparently seedless fruit, but the seeds are actually aborted while they are still small.

Is parthenocarpy and parthenogenesis the same?

Parthenocarpy leads to the development of fruits without seeds. Parthenogenesis occurs in animals, where an unfertilized ovum develops into a new individual, which is a clone of a female and mostly haploid.

What is the difference between parthenogenesis and parthenocarpy?

Parthenocarpy is the process which produces fruits from unfertilized ovules in plants. These fruits do not contain seeds. Parthenogenesis is a type of reproduction commonly shown in organisms mainly by some invertebrates and lower plants.

What is environmental parthenocarpy?

The development of fruits without pollination and fertilization is called parthenocarpy. Parthenocarpic fruits are seedless. Thus, parthenocarpy is considered the most efficient way to produce fruits under environmental conditions adverse for pollination and/or fertilization.

What is parthenocarpic cucumber?

Parthenocarpic means that the plant can set fruit without pollination. Since pollinators are not required in this case, parthenocarpic is a desirable characteristic for cucumbers grown in protected cultural system. Cucumbers are harvested in immature stages where mature seeds have not developed yet.

What is parthenocarpic tomato?

Parthenocarpy is a trait where fruit set and growth are triggered without pollination and fertilization. In the tomato (Solanum lycopersicum L.), this trait is considered attractive as it reduces the cost and labor requirements for fruit setting.
