Every american variety has its natural dispositions to prosper in any type of soil.


Physical environment

The rootstocks are characterized by the disposition and the orientation of their root system; thus :

  • some rootstocks with tracing root system  (Riparia Gloire, SO4, 41B)
  • some root stocks with tap root system  (Lot, R99)
  • some rootstocks with intermediate system  (3309, R140, 161.49, 44-53)


Milieu Chimique

  • the limestone
  • the salt

Among the most resistant varieties, let us point out : the hybrids of Solonis, 1616 and 216.3. The root stocks R 31 and the Paulsen 1103. The diverse rootstocks have a strength which is between 1 g and 1,5 g of NaCl for 1.000 of dry soil.

Biological Environment

  • Phylloxera : all present rootstocks are phylloxera proof.
  • Nematodes :
    • Resistant rootstocks : SO4, 5BB, 99 R, 1616, 44.53,
    • Fairly resistant rootstocks : 420 A, 101.14, 110 R, Riparia
    • Sensitive rootstocks : 3309, 196-17, G1, 161.49, 216.3, 31 R, 41 B
