Solution

Introduction to commensalism:

Commensalism is the interaction between two organisms belonging to two different species where one organism is benefited while the other remains unaffected.

Association between lianas and trees:

Lianas maintain erectness of their stem by taking support of other trees. They get the benefit from other trees for the support they require whereas the trees remain unaffected by the presence of lianas. In this association, lianas are benefited but trees are neither benefited, nor harmed. Therefore, the association between lianas and trees is an example of commensalism.

Final answer: Commensalism

The stem of a fruit tree X fixed in soil is cut in a slanting way. The upper part of the stem of another fruit tree Y of different variety of same species is also cut in a slanting way. The cut stem of tree Y, without roots but having some leaves, is placed over the rooted cut stem of tree X in such a way that their cut surfaces fit together properly. While joining the two cut stems, care is taken to make sure that the layer Z of one cut stem is in contact with layer Z of the other cut stem. The joint of the cut stem is bound tightly with a piece of cloth and covered properly with polythene. Soon the cut heals and the two stems grow together and become one fruit tree producing leaves, flowers and fruits.
