Suitability for cultivation and agronomic production
Plantet N is fairly fertile and displays a steady production. It can be short or moderated long pruned. It should preferably be trellissed because the shoots are very  wind sensitive  and break easily. Bud cutting capacity is low to moderate.
Sensitivity to diseases and pests
Plantet N is a fairly rustic vine variety which resists well to diseases and which can be used non-grafted in soils not prone to phylloxera.
Technological potential
Plantet N grape clusters are moderate in size and are compact. The berries are small, firm, raspberry flavor with a tendency to shatter a  bit when it reaches maturity. Wines produced are very mediocre in terms of quality and they contain no diglucoside anthocyanins.
