Question

Which of the following is as stimulative parthenocarpy?
A. Seedless cucumber
B. Seedless watermelon
C. Both A and B
D. None of the above

Answer 1

Hint:-The disorder in which fruits are formed without seed formation is known as parthenocarpy. In the year 1902, this method of fruit processing was introduced. This is largely due to the lack of fertilization, pollination, and development of embryos in plants. Parthenocarpic fruit in botany means virgin fruit. In general, these types of fruits are seedless.

Complete Answer:-
Parthenocarpy is added during cultivation, along with other plant hormones, including gibberellic acid. This results in the maturation of the ovaries without the fertilization process and produces larger and more pulpy fruits. This approach applies to all sorts of crops, from pumpkin to cucumber varieties, and much more. Parthenocarpy can be divided into two parts: vegetative and stimulative.
Vegetative - This normally takes place without pollination and no seeds are produced within the fruits due to the absence of pollination. A good example of vegetative parthenocarpy is the banana. The bananas created are sterile in this natural phase, grown without viable ovaries, and do not contain seeds, which means they have to propagate vegetatively.
Stimulative - Typically, stimulative parthenocarpy occurs without the fertilization phase. This condition occurs when a wasp's ovipositor is inserted into a flower's ovary and can also be accomplished in the unisexual flowers that are present within the syconium by flowing air or plant growth regulators.
Thus, the right option is C.

Note:- Advantages of Parthenocarpy
● This is healthier, and the consequences are quickly achieved.
● Provides fruits without seeds and enhances consistency.
● It decreases the full cost of cultivation.
● This increases the yield of crops without using organic pesticides.
● The regulators of plant growth are natural and the fruits developed are larger.
