Method Primary source abstract: "Micrografts of internodes excised from in vitro grown pear plants (Pyrus communis L. cv. 'Bosc' (B) and cv. 'Butirra Hardy' (BH)) and quince (Cydonia oblonga Mill. East Malling clone C (EMC)), were cultured aseptically to test the effectiveness of their functional vascular reconnection in relation to incompatibility-compatibility relationships that these genotypes exhibit in the field."
Comments P.10 left column bottom paragraph: "In horticulture, quince is often used as a rootstock for pear scions, and compatible cultivars show phloem connectivity within 10−20 days after grafting (primary source). Certain incompatible combinations show limited phloem connectivity even 30 days after grafting and xylem differentiation is delayed (Espen et al., 2005). This type of incompatibility is presumably quite common between unrelated species and is straightforward to identify due to poor growth or death."
