Title: A Simple Method for Field Identification of Mahaleb (Prunus mahaleb L.) Cherry Rootstock
Author: R.L. Perry
Most sweet and sour (Amarelle) cherry cultivars have long been graft ed onto P. avium L. (mazzard) or P. mahaleb L. (mahaleb) rootstocks (3,4, 5). These plants differ greatly in their botanical characteristics (5,10) and in their adaptability to environments and subsequent rootstock performance (3, 4, 5, 10). For example, mahaleb performs well in deep well-drained soils, but does not tolerate anaerobic conditions, while mazzard tolerates heavier soils better but is subject to drought stress in sandy-porous soils (2,3,4,6). Mahaleb is more susceptible to root rots caused by Phytophthora and Armillarea, while mazzard is more sus ceptible to crown gall and to lesion nematodes (4, 7, 9). Scion cultivars infected with X-disease live longer on mahaleb and symptom expression differs according to the rootstock (4, 6). In the west, gophers show preference for mahaleb rooted trees over mazzard (4). In colder climates, mazzard roots are known to be more sensitive to low temperature than mahaleb (1, 2).
