Read the given statements and identify the PGRs $X, Y$ and $Z$.
$\mathrm{X}$ induces accumulation of salts inside the cells.
Y promotes rapid elongation of leaf bases and internodes in deep water rice plants.
(iii) Application of $Z$ to leaves shall reduce transpiration.

Solution
Cytokinins induce accumulation of salts inside the cells. Ethylene promotes rapid elongation of leaf bases and internodes in deep water rice plants. As a result, leaves remain above water. Application of minute quantity of abscisic acid to leaves shall reduce transpiration to a great extent through partial closure of stomata. It conserves water and reduces the requirement of irrigation.
