| Characteristics |
140 Ru is a very vigorous rootstock. Therefore, it is not advisable to use it in very fertile soils or in grape varieties sensitive to blossom drop.
The response to rooting is low, but local grafting shows good results.
The rootstocks’ resistance to active limestone is of 17 to 20%.
140 Ru often has galls on its leaves, due to the gall form of phylloxera.
It has good resistance to drought and adapts well to dry and limestone soils. On the other hand, its use is contraindicated in very moist soils. |
