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.

Column $I$ (Hormone)	Column $II$ (Effect/Function)
$(a)$ Auxins	$(i)$ Produces male flowers on female plant
$(b)$ Gibberellins	$(ii)$ Parthenocarpy in orange,lemon and grapes
$(c)$ Cytokinin	$(iii)$ Antitranspirant and stress tolerance in plants
$(d)$ Abscisic acid	$(iv)$ Reverses apical dominance in plants

It takes a very long time for pineapple plants to produce flowers. Which combination of hormones can be applied to artificially induce flowering in pineapple plants throughout the year to increase yield?
