This seed pad reduces the volume of the apricot-tree volume, which allows for thicker seeding. The tree is of moderate growth, with a spherical form. The fruits are large, with a mean weight of 30 g. The pit is 1.25 g in weight, dark brown, ovally-elongated at the base and tip, with a clearly-defined, deep furrow of the backbone stitch, and a small rowing of the abdominal stitch.The green Reine-Claude CD4 is a seed pad, a form of the plum variety Green Reine-Claude, intended to engraft the apricot tree.The tree has a moderate growth with a spherical form. The stem is thick, while the skeleton branches emerge at an angle of 40 degree.The fruits are large (38X33X35mm) with an average weight of 30 g. Their flesh is light brown to yellow and is well segregated from the pit.The green Reine-Claude CD4 is compatible with the main apricot varieties ("Hungarian", "Louisette", "Festival", "Silistrian compote", "Umberto", "Roxana", etc.). The concrescence is very good and no differentiations in the accretion of the engraftment and the pad in the realm of the engrafting are noticeable. The volume of the tree crowns, engrafted on it, is 20 to 40 % smaller than that of the "Damson 4 pad" and the apricot. This volume allows for the increase in the number of plants per acre. The output in kg from a tree, reported per cubic meter of the crown's volume, is about 23% higher than that of the "Damson 4 pad".
