Question

Parthenocarpic development of fruit is brought about by ..............

• A. NAA and 2-T
• B. 2, 4, 5-T
• C. 2, 4-D
• D. None of the above

Answer 1

The correct option is B 2, 4, 5-T

Parthenocarpy is a method adopted to have seedless fruit. Parthenocarpy have been introduced in many crops like cucumber, tomato, bottle gourd, brinjal, cucurbits, watermelons, etc. by exogenous application of phytohormones like auxins, gibberellins and cytokinin. Stewart and Condit in 1949 found out that sprayings of 2,4-D and 2,4,5-T will induce parthenocarpic fruits. 2,4-T not only induces parthenocarpic fruits but it also causes early maturation of fruits.
