Question

which Chemical substance responsible the development of fruit by Parthenocarpy is ______________acid. ​

Answer 1

Answer:

In angiosperms, auxin phytohormones play a crucial regulatory role in fruit initiation. The expression of auxin biosynthesis genes in ovules and placenta results in uncoupling of tomato (Solanum lycopersicum) fruit development from fertilization with production of parthenocarpic fruits.

Answer 2

The Chemical substance responsible the development of fruit by Parthenocarpy is Gibberellin, auxin and cytokinin. ​

Explanation:

• Gibberellin, auxin and cytokinin could stimulate the development of parthenocarpic fruit.
• The development of of fruit without fertilization is termed as parthenocarpy.
• Fruits produced by parthenocarpy are seedless.
• Auxin treatment of young, unpollinated ovaries in certain cultivars of strawberry, tomato, grape, and orange is known to cause production of parthenocarpic fruit.
• Parthenocarpy in plants is a relatively unusual condition but it does occur in some of our most common fruit.
• This circumstance occurs when the ovary of a flower develops into a fruit without fertilization.
• The result is a seedless fruit.
• Parthenocarpy (fruit set in the absence of fertilization) is a trait which can increase fruit quantity and quality from pollinator dependent crops by removing the need for pollination.
