Q. Identify the pair of physiological effects of two phytohormones, which are synthesized from different amino acids? Formation of perennating buds in $Lemna$. Simultaneous flowering in pineapple. Bolting in cabbage. Apical dominance in $Polyalthia.$
A) II and IV
B) I and IV
C) II and III
D) I and II
Explanation
Auxin is synthesized in shoot apices, leaf primordia from amino acid tryptophan and cause apical dominance. NAA and 2, 4- D (both auxins) are employed for inducing flowering in litchi and pineapple. Buds develop when cytokinins are in excess.
