Use(s): Rootstock Richter 110 is recommended for hillsides or dry-farmed sites where drought is likely. On such sites, it usually out yields St. George and has better yield:pruning weight ratios. On deep fertile sites 110R can induce too much vigor in scions, causing vegetative characters in wines and poor bud fruitfulness. There are also reports of potassium deficiency on heavy soils. 110R can be relatively slow to establish, but its vigor increases as the vines establish. This rootstock has good phylloxera resistance, but is susceptible to root-knot and dagger nematodes. 110R has small leaves with a wide U-shaped petiolar sinus, scattered hairs on the petioles, shoot tip and internodes, and its sun-exposed shoots are purple.
