Vedclass · Answer

(A) Pineapple plants have a long vegetative growth phase before flowering. To induce flowering artificially and ensure year-round production,specific plant growth regulators are used. $Auxins$ (like $NAA$ or $2,4-D$) and $Ethylene$ are widely used in commercial pineapple cultivation to promote synchronous flowering. $Ethylene$ is particularly effective in inducing flowering in pineapple,while $Auxins$ help in fruit development and uniform ripening. Therefore,the combination of $Auxin$ and $Ethylene$ is the correct choice for increasing yield.

$a.$ Auxin	$(i)$ Root hair formation
$b.$ Cytokinin	$(ii)$ Seed development
$c.$ Ethylene	$(iii)$ Xylem differentiation
