Vedclass · Answer

(A) Auxins are a class of plant hormones that play a crucial role in plant growth and development. The primary physiological effects include:$1$. Apical Dominance: Auxins produced in the apical bud inhibit the growth of lateral buds,ensuring the plant grows vertically.$2$. Cell Elongation: They promote the elongation of stems and coleoptiles by increasing cell wall plasticity.$3$. Root Initiation: Auxins are widely used in horticulture to induce root formation in stem cuttings.$4$. Fruit Development: They promote fruit growth and prevent premature fruit drop (e.g.,in apples).$5$. Weed Control: Synthetic auxins like $2,4-D$ are used as herbicides to kill broad-leaved weeds without affecting monocot crops.
