When a plant's shoot tip is replaced with an agar block containing auxin, it maintains apical dominance, inhibiting lateral shoot growth and promoting vertical growth.
When the shoot tip of a plant is cut off and replaced by an agar block containing auxin, it maintains apical dominance. This means that the plant will continue to grow vertically and inhibit the growth of lateral shoots.
Auxin is a plant hormone that plays a crucial role in controlling plant growth and development, including promoting elongation and inhibiting lateral bud growth.
This phenomenon has been demonstrated through various experiments involving coleoptiles and agar blocks that showed the effects of auxin on plant growth.
