- 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 r: resistant; S: susceptible.
- b Number of inoculated seedlings.
- c Suggest wilting commission ± SE.
- d Emails term homogeneous teams by Fisher’s LSD test (P = 0·05).
Hydraulic conductivity and you may susceptability so you’re able 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: unwilling, S: susceptible. Suggest worth ± SE. Emails term homogeneous teams in this a variable (P = 0·05, Fisher’s LSD means).
- cP-worth regarding the anova.
- *log-transformed in order to meet anova criteria; **inverse-turned in order to meet anova requirements.
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).
Anatomical has
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). Pokračovat ve čtení „Water possible and you may gas exchange immediately following DED inoculation“
