Figures & Tables

Figure 1

Population densities of Pratylenchus penetrans (per kg soil, roots inclusive) under Gi.3, Gi.5, and Gi.6 trees during the course of the study, at the Summerland, British Columbia (BC, solid lines) and Kentville, Nova Scotia (NS, dashed lines) sites. Error bars represent one standard deviation above the minimum value at each date.

Temporal dynamics of the biomass of fine roots (<2 mm diameter) (g dry root/kg dry soil) under Gi.3, Gi.5, and Gi.6 trees during the course of the study, at the Summerland, British Columbia (BC, solid lines) and Kentville, Nova Scotia (NS, dashed lines) sites.

Relationships between running average Pratylenchus penetrans population densities and trunk cross-sectional areas (TCSA) for three different cherry tree training systems on Gisela 3 rootstock from 2013 through 2016 at the Summerland, British Columbia site. Training systems: KGB, Kym Greene Bush; TSA, Tall Spindle Axe; UFO, Upright Fruiting Offshoots.

Main-factor effects (averaged over sample dates) of Gisela 3 (Gi_3), Gisela 5 (Gi_5), and Gisela 6 (Gi_6) rootstocks and training systems (KGB, Kym Greene Bush; TSA, Tall Spindle Axe; UFO, Upright Fruiting Offshoot) on P_ penetrans population densities in soil alone (Pp/kg soil), roots (Pp/g dry root), and soil and roots combined (Pp/kg soil with roots), at Summerland, British Columbia, and Kentville, Nova Scotia sites_ For both sites and all nematode population parameters, sample date had a significant main-factor effect but there were no significant sample date × fixed factor interactions_ Values labelled with different letters are significantly different (paired t-tests, p < 0_05)_
