Rootstock is a type of agricultural practice where a plant's root system is used to support the growth of another plant, known as the scion. This technique is commonly used in horticulture to enhance the growth, disease resistance, and overall health of fruit trees and other plants. By selecting a compatible rootstock, growers can improve yield and adapt plants to different soil conditions. In viticulture, grapevines are often grafted onto specific rootstocks to improve their resilience against pests and diseases. Different rootstocks can influence the flavor and quality of the grapes produced, making this practice essential for winemakers aiming for high-quality wines.
