Question

Match the phytohormones given in column I with their functions given in column II. Choose the answer with the correct combination of the alphabets of the two-column.

	Column -I (Phytohormones)		Column - II (Function)
A	Auxins	(p)	Elongation of genetic dwarf plants
B	Gibberellins	(q)	Inducing fruit ripening
C	Cytokinins	(r)	Formation of the abscission layer
D	Ethylene	(s)	Root initiation on cutting the stem
		(t)	Richmond lang effect

• A. A = r, B = s, C = p, D = t
• B. A = p, B = r, C = q, D = s
• C. A = s, B = t, C = r, D = q
• D. A = s, B = p, C = t, D = q

Answer 1

Answer: (D)

Auxin promotes rooting in stem cutting. Gibberellins causes elongation of stem in genetically dwarf plants, it causes rapid internodal elongation known as bolting. Cytokinins delays the process of senescence known as Richmond - Lang effect. Ethylene is fruit ripening hormone.
