## Hydraulic conductivity and you will susceptability so you can cavitation

Vulnerability to cavitation (P_{fifty} and P_{80}), Kx_{maximum} 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).

Despite P_{80} and Kx_{max} 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 possess

Maximum vessel length (VL_{max}) 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). There was a negative correlation between Kx_{max} (log-transformed) and bVL (R 2 = 34·5, P = 0·0026; Table S1): plants with shorter vessels had lower conductivity.

S ? S progeny showed the widest vessels (VD; Table 3), and were unique in having vessel diameters greater than 90 ?m (Fig. 2b). The progeny of the S ? S cross also had larger VTA, and a THC twice as high as the other two groups (Table 3). CLVF, CMVF and CSVF did not differ among crossing types (P > 0·05, Table 3). As expected, Kx_{max} (log-transformed) was positively correlated with https://datingranking.net/pl/loveaholics-recenzja THC (R 2 = 32·6, P = 0·0035; Table S1) and VD (R 2 = 28·8, P = 0·0068; Table S1). In addition, R ? R individuals showed a significantly higher VF (c. 20%) and a greater (t/b) 2 (P < 0·05; Table 3). Meanwhile, S ? S saplings had significantly higher PGV (Table 3). There were no differences in WD, VPG or VGA between the groups (P > 0·05; Table 3).

Both ?_{pd} and ?_{md} progressively decreased after DED inoculation (Fig. 3a). Seventeen d.a.i., ?_{pd} had dropped more than 0·25 MPa and 47 d.a.i. c. 1 MPa, independent of the type of crossing (Fig. 3a). ?_{md} dropped from ?1 MPa to almost ?3 MPa in S ? S progeny at the end of the experiment. From the thirteenth d.a.i., ?_{md} of R ? R cross progeny was significantly different from S ? S cross progeny.
