Which of the following is wrong about ethylene.
A
Inhibit growth of root
B
Ripening of fruits
C
Elongation of stem in paddy

Promote senescence of leaves & flowers
Correct Answer
Option C
Detailed Explanation
The correct answer is C) Elongation of stem in paddy because ethylene is known to inhibit stem elongation rather than promote it. Ethylene primarily functions to regulate processes such as fruit ripening, leaf and flower senescence, and the inhibition of root growth, but it does not encourage the elongation of stems in plants like paddy.
