Linear regressions calculated between pre-rooting glucose in the basal stem (A), pre-rooting Nt in whole cuttings (B), pre-rooting glucose in leaves (C), and total sugars in the basal stem at day 6 (D) as independent variables and the subsequent survival (A) and number of roots (B, C, D) as dependent variables. Encircled plots in (B) and plots with black (unstored cuttings) and white (stored cuttings) centres in (C, D) represent non-nitrogen-deficient cuttings (n = 36). All cuttings, n = 54; unstored cuttings, n = 27.
