Research on the growth and development of planting material for the walnut grafted usingthe chip budding method

Abstract

The determinations aimed to study the growth and development of four walnut varieties (Anica, Grădinari, Miroslava and Velniţa) grafted usingthe Chip budding method. Biometric observations focused on the percentage of grafting success, and the height and diameter of the trees. In addition to biometric observations, biochemical determinations were performed on the content of photosynthetic pigments and peroxidase activity for thegrafted combinations in the first year of vegetation.The research results highlighted differences between the four walnut varieties in terms of growth vigor, photosynthetic pigment content and peroxidase activity.
