OTHER INFORMATION

Behavior in the nursery: easy rooting aptitude; the root system tends to expand sometimes to a considerable depth; it induces good vigor.
Behavior in the propagation block: it tends to produce a lot of wood, both raised on the ground and on trellis.
Behavior in the open field: it induces good vigor and productivity; it lengthens the cycle; it is well adapted to acidic soils; it shows an average resistance to drought and salinity. To be avoided in combination with very productive varieties that are sensitive to coulure.
