In the evaluation of the roots of plants I for the number of ground pearl cysts, an average of 4.2 cysts per plant was reported, a value lower than observed by other authors under field conditions (BOTTON & COLLETA, 2010; BROETTO et al., 2011).
The number of ground pearl cysts is little affected by the making of drains or ridges in preplanting of rootstocks, and is not correlated with the incidence of decline and death of plants.
Pearl cysts are small, white, solid lesions with opaque walls located in the stroma and are not connected to the wound.
