Detailed explanation-1: -So, if you cut tip of stem, it will break apical dominance.
Detailed explanation-2: -Results of the present study suggest that negative phototropism can occur when the level of auxin or of auxin signaling is reduced to a minimal level, and that negative phototropism is the basal response to unilateral blue-light irradiation in plant axial organs.
Detailed explanation-3: -Updated On: 27-06-2022. If the stem tip of the plant is cut, apical growth of the plant stops growing. Lateral buds start growing due to which branches are formed.
Detailed explanation-4: -Application of unilateral light triggers the curvature of growing plant organs away or towards the light source; this phenomenon is known as phototropism.
