Resistance to soil parasites
44-53 M displays a good tolerance level to radicicolae phylloxera. On the other hand, it displays moderate resistance to Meloidogyne arenaria nematodes and it is susceptible to Meloidogyne incognita nematodes.
Adapt to environment
The tolerance level of 44-53 M to chlorosis is low to moderate. It resists just up to 15% total limestone, 10% active limestone and a CPI of 10, but it is well adapted to drought. In terms of mineral input, 44-53 M does not absorb magnesium easily and it favors the onset of magnesium deficiency symptoms. 44-53 M is well adapted to fairly deep hard limestone soils, with a low tendency to induce chlorosis.
Interaction with grafts and production objectives
44-53 M displays good afinity to grafts and the speed of development of the plants is moderate. Low to moderate rootstock vigor with balanced vegetative growth. Products obatiend with plants grafted on thsi rootstock are usually of good quality. Blending with Grenache N andGamay N, provide good results.
Aptitudes for plant propagation
44-53 M wood production is moderate (30 000 to 50 000 m/ha) and the vine shoots lignify easily. This root stock likewise présents good propagation by cuttings and grafting capacity.
Resistance to aerial parasites
This root stock is not very susceptible to gallicolae phylloxera and displays very good resistance to downy mildew.
Clonal selection in France
The 4 approved 44-53 M clones carry the numbers 120, 755, 1104 and 1161.
