(a)applying trace elements in tomato fields
(b)spraying mineral solution on plants
(c)spraying hormones on flowers
(d)applying fertilisers containing radioactive elements
Attempt This Question
Not attemptedCorrect Answer: (c) spraying hormones on flowers
Spraying auxin-type plant hormones on tomato flowers induces parthenocarpy, causing the ovary to develop into a fruit without fertilisation, hence seedless tomatoes. Trace elements, mineral sprays or radioactive fertilisers do not reliably trigger seedless fruit set.
