Variety traits
Vitis berlandieri Planch x Vitis rupestris Scheele
The vegetation period of Vitis berlandieri x Vitis rupestris hybrids is characterized as mid-late, which reduces the risk of shoot damage from spring frosts compared to early rootstock groups.
In the reference 5 varieties crop Vitis berlandieri Planch x Vitis rupestris Scheele, where this is mentioned in the description.
These hybrids, used as rootstocks, are distinguished by a later onset of vegetation compared to groups based on Vitis riparia. The onset of flowering in these can occur 12–15 days later, which is a significant agrotechnical advantage in regions with a risk of late spring frosts.
The duration of the vegetation period is a varietal characteristic of specific hybrid forms; for example, for the Ruggeri 140 rootstock, this figure is about 177 days. The adaptive properties of this cycle ensure normal development of the Vitis vinifera scion in dry climates and on soils with a high active lime content.
