Size-Controlling Cherry Rootstock Selection Based on Root Anatomical Characteristics

Over the past few decades, numerous studies investigated vigor and productivity of fruit species depending on rootstock which they were grafted, but exact size-controlling mechanism itself has not been fully elucidated, nor rapid selection methods defined. Thus, this study aimed to assess root anatomical characteristics their influence overall ‘Summit’ cherry tree confirm effect establish an effective protocol for selection. Plant material included three (Prunus cerasus, Prunus fruticosa, mahaleb) interspecific hybrid ‘Gisela 5′ (P. cerasus × canescens) as a control. The detailed analysis samples with differentiated secondary structure taken from sampling depth 10–15 cm. Roots percentages vessels ≈40%, ≈50%, ≈10% belonging size-classes ˂700 µm2, 700–2000 μm2, ˃2000 µm2 (respectively) are presumed provide optimal amounts water solution scion, without compromising plant vitality, drought tolerance, effect. Statistically significant correlations determined between properties (the percentage vessels, especially xylem porosity, hydraulic conductivity, both per mm2 total root) vegetative growth in juvenile phase, indicating direct vessel size its employment
