- P is the significance level of the factor (n.s.: not significant; *<0·05; **<0·01; ***<0·001). % is the percentage of variability explained by the factor. Factors that have not been considered in the model are represented with a dash (–).
- a roentgen: resistant; S: susceptible.
- b asiatische Dating-Seiten kostenlos Quantity of inoculated seedlings.
- c Imply wilting payment ± SE.
- d Emails name homogeneous communities from the Fisher’s LSD sample (P = 0·05).
Hydraulic conductivity and vulnerability to cavitation
Vulnerability to cavitation (Pfifty and P80), Kxmaximum and absolute conductivity (Kx) did not differ significantly among the types of crosses (Fig. 1; Table 3). Loss of conductivity began at ?0·3 MPa and progressed at a similar rate in all crosses, i.e. there were no differences in the slope of VCs (P = 0·87; Table 3).
- a WP 20 d.a.i., wilting percentage 20 days after inoculation; VC slope, ‘a’ parameter of the exponential sigmoid: PLC = 100/(1 + exp[a(??b)]); P50, applied pressure at which the sample loses 50% hydraulic conductance; P80, applied pressure at which the sample loses 80% hydraulic conductance; Kxmax, maximum xylem specific conductivity; VLmax, maximum vessel length; bVL, vessel length distribution parameter; WD, wood density; VD, vessel diameter; VTA, vessel transectional area; THC, relative theoretical hydraulic conductance; VF, vessel frequency; (t/b) 2 , resistance to implosion; PGV, percentage of grouped vessels; VPG, vessels per group; VGA, vessel groups per area; CLVF, contribution of large vessels (VD >70 ?m) to flow; CMVF, contribution of medium vessels (40 < VD < 70 ?m) to flow; CSVF, contribution of small vessels (VD <40 ?m) to flow.
- b Roentgen: resistant, S: prone. Suggest value ± SE. Letters title homogeneous communities in this a variable (P = 0·05, Fisher’s LSD strategy).
- cP-worthy of on the anova.
- *log-turned meet up with anova criteria; **inverse-transformed meet up with anova conditions.
Despite P80 and Kxmax not differing between crossing types, these variables were positively correlated with WP 20 d.a.i. for the 24 selected trees (P < 0·05; Table S1). Nevertheless, the coefficient of correlation was low in both cases (R 2 < 0·20).
Maximum vessel length (VLmax) ranged from 69 to 118 mm. S ? S trees had 30–40% significantly longer conduits and a higher percentage of longer vessels (Fig. 2a; Table 3).
