The phenomenon known as moria in kiwi plants it appears to be a serious threat causing disastrous problems throughout Italy. Studies illustrating that there is a correlation between the soil structure and moisture lead to this catastrophic phenomenon. The fact that young symptomatic plants were uprooted and later transplanted on different soil conditions, were in fact recovered, indicates that there is indeed link to the degraded soil of the cultivation.
Savior1 (SAV1) is a rootstock that has been identified from a 1997 experiment in New Zealand and was initially presented as a Psa-V tolerant rootstock.
In New Zealand it has been used as a rootstock for more than 15 years. Today it is widespread thanks to its ability to endure soil conditions such as anoxia / asphyxia, while at the same time it grows deep in heavy soils. It has the characteristics to endure where waterlogging is taking place.

Soils: for anoxic and clay soils which cause soil asphyxia
Resistant: tolerates orchards waterlogging better regarding kiwi plants without rootstock
1. Tolerance to radical asphyxia / drought:
the root system develops in depth, guaranteeing the plant the water supply it needs
2. Lower water requirement: It creates deeper root system and along with the less vigor, the plant needs less water quantities or wider space between the irrigation events
KIWI VARIETIES GRAFTED ON SAV1
- Higher number of flowers
- Higher dry matter of fruits
- Higher productivity (resulted in the additional production of trays/ha.)
- Higher tolerance in terms of degraded soils
- Grafting compatible with both A. deliciosa and A. chinensis
- Better precociousness as it regularly causes earlier harvest
SAV1 has excellent characteristics in terms of resistance and productivity, which combined with the correct agronomic management, can guarantee the producing of quality kiwi even in an increasingly adverse environment.
