“…Indeed, we found that maximum vessel lengths were typically 5.6 times longer than mean vessel lengths. Importantly, all species exhibited very similar vessel length distributions (i.e., the shape of the vessel length distribution curve) consistent with Nijsse (2004) , with the predominant difference between species occurring in shifts in the lengths associated with the peak and tail of the distribution (i.e., in the mean vessel length and maximum vessel length) (see Fig. 1 ).…”

Many traits often assumed to be linked to vessel length, including growth ring porosity and vessel diameter, are not associated with vessel length when compared interspecifically. Sampling for vessel length has been nonrandom, e.g., there are virtually no data available for roots, and sampling for environment has been confounded with sampling for habit. Increased knowledge of vessel length is key to understanding the structure and function of the plant hydraulic pathway.

“…After impregnation with latex particles, the stem segments were cut serially starting 5 mm from the distal cut-end using a razor blade, and the number of latex paint-filled vessels in each cross-sectional cut was counted using a binocular microscope (Leica MZ8; Leica, Heerbrugg, Switzerland). As previously observed in the stems of many plant species (Nijsse, 2004), including Z. elegans, the relationship between the distance from the distal cut surface and the number of paint-filled vessels followed an exponential decay. The xylem vessel length distribution was deduced from this decay, and described by the half-length ( ; 50% of the vessels being shorter than this length) and maximum vessel length (L max ) according to Nijsse (2004).…”

“…All current methods to measure vessel lengths are laborious, indirect, and based on determining the distribution of vessel lengths by counting the number of continuous vessels in different lengths of a stem segment (Skene and Balodis, 1968;Zimmermann and Jeje, 1981;Ewers and Fisher, 1989a;Nijsse, 2001;2004;Tyree and Zimmermann, 2002). Many comparisons of vessel length distributions have been made between species (Zimmermann and Jeje, 1981;Hacke et al, 2006), but little is known about the specific effects of environmental stress on the distribution of vessel lengths within a species.…”

Intervarietal differences in xylem structure could significantly affect water transport as well as vulnerability to cavitations and thus crop yield. Evaluation of crop varieties with respect to the specific traits can be thus helpful in breeding and agricultural practice. In the present study we compared basic anatomical traits (vessel length and diameter) as well as theoretical and measured hydraulic conductivities (K) of xylem in stems of three hop varieties (Agnus, Saaz hop -Osvald's clone 31, Vital). There were no statistically significant intervarietal differences in measured K (overall mean 1.68 × 10 -6 m 4 /MPa/s), the ratio between K and theoretical conductivity (mean = 0.194), as well as vessel diameter and vessel length distributions. The only noticeable difference was in the distribution of vessels with the diameter ≥ 100 µm which differed in Vital compared to Agnus or Osvald's clone 31 (Kruskal-Wallis test, P < 0.001). Our results thus indicate highly conservative nature of xylem basic functional and anatomical characteristics in hop varieties studied.
