Description: The graft union is the critical point where the graft and the rootstock merge in the grafting process. This process is fundamental in horticulture and agriculture, as it allows for the combination of desirable characteristics from two different plants into one. The graft, which is the upper part of the plant to be propagated, is joined to the rootstock, which provides support and nutrients. The quality of this union is essential for the success of the graft, as a proper fusion ensures that both parts integrate effectively, allowing for the flow of water and nutrients. The graft union can be influenced by various factors, including genetic compatibility between the plants, the grafting technique used, and environmental conditions. A successful union not only promotes healthy plant growth but can also enhance resistance to diseases and pests, as well as adaptation to different soil types. In summary, the graft union is a crucial aspect of plant propagation, combining the science and art of horticulture to create new varieties and improve agricultural production.
