A) Auxin
B) Ethylene
C) Cytokinin
D) GA
Correct Answer: B
Solution :
Ethylene is a gaseous plant hormone. It plays a key role in abscission of leaves, flower and fruits. It also hastens the ripening of fruits. Auxin suppresses the growth of lateral buds and plays a major role in the stem elongation, bending of stem towards the light side. Cytokinins stimulate cell division and delay senescence by mobilising food from other leaf parts. Gibberellin hormones take pan in the stem elongation in leaves and stem. parthenocarpy in fruits and in breaking of seed dormancy.
