UNDER GRAFTING / OVER GRAFTING LINKAGE AND THE ARCHITECTURE OF THE ROOT SYSTEM OF THE APPLE IN THE

Knowing how a tree's root system develops under different climatic conditions is an important indicator since it has a direct impact on the progress and productivity of the plant. Knowing the distribution and nature of the root system can help you get the most out of fertiliser, irrigation, and pollution prevention. We wanted to figure out what the rootstock-cultivar relationship is and how it impacts the root system's geographic distribution and structure depending on the cultivar and the tree's age in this study.

The research was carried out in the Albanian Coastal Lowlands, where roughly 30% of new apple orchards are now being planted. The study comprised cultivars like as 'Starking,' 'Golden Delicious,' and 'Gala,' which were grafted on the 'M9' under grafting (rootsotcks). The cross-strain approach was used to investigate the root system.

The results demonstrated that, despite its difficulties, the trenched-profile approach provides valuable information about the dispersion of the apple tree root system, allowing us to deliver appropriate agro-technical services. The root mass (about 80%) of all three cultivars studied is found in depths up to 70 cm and widths up to 120 cm. Approximately 90% of the roots have been dispersed. We see a considerable drop in the overall number of roots (approximately 30%) and a change in their structure once we reach the age of ten. All three cultivars have the same root system typology, which is a feature of the under grafting genome. Cv. 'Starking' has the highest level of compliance of the three cultivars studied. The scion has influenced the amount of roots and the nature of their distribution, while the rootstock has influenced the vegetation and aspects of cultivar cultivation.
