Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Parthenocarpy is induced by
A
AUXINS
B
CYTOKININS
C
ETHYLENE
D
GIBBERELLINS
Explanation: 

Detailed explanation-1: -To date the role of cytokinins (CKs) in the fruit development is less understood. Here, we showed that parthenocarpic fruit could be induced by 1-(2-chloro-4-pyridyl)-3-phenylurea (CPPU, an active CK) in tomato ( Solanum lycopersicum cv.

Detailed explanation-2: -Plant hormones such as auxin can induce parthenocarpy in various plants, including cucumber, tomato, and muskmelon (Mariotti et al., 2011).

Detailed explanation-3: -The spontaneous or chemically induced generation of fruit without ovule fertilisation is known as parthenocarpy. As a result, the fruit is seedless. Any of the plant hormones gibberellin, auxin, and cytokinin, when sprayed on flowers, will commonly induce the growth of parthenocarpic fruit.

Detailed explanation-4: -Parthenocarpy is the natural or artificially induced production of fruit without fertilization of ovules. The fruit is therefore seedless. When sprayed on flowers, any of the plant hormones gibberellin, auxin and cytokinin can often stimulate the development of parthenocarpic fruit.

Detailed explanation-5: -Fruit set and development are dependent on auxin, gibberellin, and cytokinin, which cause parthenocarpic development in many species when applied ectopically.
