Seedless fruits can be obtained by treating the unpollinated ovaries with :-a)Colchicineb)Sucrose solutionc)Hormonesd)Pure lanolinCorrect answer is option 'C'. Can you explain this answer?

Question

Answer

Seedless fruits like grapes and papaya are called as parthenocarpic fruits. These fruits are developed from unfertilized ovaries. Plant hormones like auxins induce parthenocarpy, e.g., in tomatoes.

Answer

Seedless fruits can be obtained by treating the unpollinated ovaries with auxin.auxin is plants Harmon.

Answer

Seedless fruits like grapes and papaya are called as parthenocarpic fruits. These fruits are developed from unfertilized ovaries. Plant hormones like auxins induce parthenocarpy, e.g., in  tomatoes.

Answer

Seedless fruits are obtained by spraying the flowers with growth hormone,
the ovary gets converted into fruit before fertilisation,
and because fertilization isn't occured, the seed does not develop in the fruit

Answer

Introduction to Seedless Fruits
Seedless fruits, also known as parthenocarpic fruits, are developed without fertilization and do not contain seeds. The process of obtaining these fruits involves specific treatments to the ovaries of flowers.
Role of Hormones in Seedless Fruit Development
- Hormones, particularly plant growth regulators, play a crucial role in stimulating the development of seedless fruits.
- When unpollinated ovaries are treated with hormones such as auxins and gibberellins, it encourages the growth of the ovary into a fruit despite the absence of fertilization.
Why Other Options are Not Effective
- Colchicine: This chemical is primarily used to induce polyploidy in plants, which can lead to larger fruits but does not directly promote seedless fruit development.
- Sucrose Solution: While sucrose can provide energy for plant growth, it does not have the specific role in triggering the hormonal changes necessary for fruit development without fertilization.
- Pure Lanolin: This substance is a natural wax and does not interact with plant hormonal pathways to stimulate the development of fruits.
Conclusion
In conclusion, the treatment of unpollinated ovaries with hormones is effective for producing seedless fruits. Hormones help in mimicking the natural processes that occur during fertilization, allowing the fruit to develop without seeds. Therefore, the correct choice for obtaining seedless fruits is option 'C' - Hormones.
