Question

Ok here it goes...

In the process of girdling, the pheloem and cambium is cut off together..

as for pheloem we cut it to block the food from getting downward to the lower part of the plant(or is there any other reason for us 2 do so?)

The main question is why do we cut cambium together with pheloem.If we dindt what will happen and whats the function of the cambium

Answer 1

The cambium is located between the phloem and the xylem. New phloem and xylem develop from the cambium causing the plant to grow in thickness. If you girdle the tree the phloem is removed since it is part of the bark. This exposes the wet cambium and kills the cells. Now the plant cannot create new phloem and xylem. The lower part of the tree will eventually die due to lack of food, since the phloem was cut and cannot transport the food from t he leaves. The area above the girdle will continue to grow since the cambium is still intact. The plant will eventuall die unless you preform a bridge graft connecting the two areas again.

Answer 2

The easy answer is that the cambium is on the outside, so to cut the phloem you also cut the cambium. More importantly, the cambium is the layer in which growth and the production of new phloem occurs.
