Scientists Aut University in New Zealand found that the stump of the new Zealand Kauri (agathis South) is a living part of a giant superorganism, which involves dozens or even hundreds of trees. While the stump remains active as a parasite. This publication reports Live Science.
According to the researchers, the stump would remain dead, if it had not been connected with the root system of other trees, because it does not have its own green photosynthetic tissue. At night he gets the water and nutrients that other plants receive throughout the day.
Scientists have tracked the movement of nutrient juice and has determined that the tree and stump have consumed water in different times of the day. Day stump, “idle”, while live plants transporterowych moisture until their roots and leaves. Night stump moved the water through its tissue. Thus, trees act as pumps that alternately included in a single hydraulic system. According to scientists, the remains of a tree can play the role of a bridge linking root systems to each other.
At the same time, such a system is vulnerable to pathogens that can spread from one infected tree to the entire forest through the roots.
