Question

If a stem is girdled which dies first root or stem?

Answer 1

Girdling refers to a process in which the bark encircling the tree is removed completely. The phloem layer of tissue is present just beneath the bark, and it is responsible for the transportation of food prepared in the leaves of the plant through photosynthesis to the roots. Thus, phloem facilitates downward movement of food, and if the stem is girdled the roots of the plant will not able to capture food and die first.
