If a plant is girdled, which part of the plant dies first- the root or the shoot? Answer by giving reasons. |

Answer» In a ring girdled plant, the root dies first. A ring of bark is cut from the stem. It also removes phloem. Nutrients collect above the ring where the bark also swells up and may give rise to adventitious roots. Growth is vigorous above the root. The tissues below the ring not only show stoppage of growth but also begin to shrivel (contract). Roots begin to starve first if the ring is not healed, after sometime roots will die, which will kill the whole plant. |
