Table 3 Variance components (expressed as % of total variance) of the rootstock, scion and their interaction based on the analysis of 4 groups of rootstock/scion combinations: (a) clonal vigour classes (V/V, V/v, v/V and v/v) and (b) flowering capacity (F/F, F/f, f/F and f/f) (trial 1; age 18 for all traits except HT: age 10) (see Table 2 for explanation of codes)

From: Rootstock effects on growth, reproduction and wood properties in hybrid larch (Larix x eurolepis Henry) and in some other Larix sp. grafting associations
