tukipyynnöstä

Tukipyynnöstä refers to a specific phenomenon occurring in trees, particularly in those with a sensitive or damaged graft union. The term specifically focuses on the processes leading to failure of the graft union due to physiological or mechanical stress.

In trees, grafting is a common technique used for propagation and rejuvenation. The operation involves joining a piece of stem (scion) from one tree onto the root system (rootstock) of another. This technology allows for the duplication and multiplication of prized tree varieties, permitting skilled horticulturists to cultivate high-quality rootstocks efficiently.

However, transplanting branches between unconnected trees can make the graft union (the region connecting the scion to the rootstock) susceptible to various physiological or environmental ailments. These include physical shock due to variable weather, pathogen attack, or mechanical disruptions during the initial adaptation stages of the tree.
