Abstract Aims Since plants are compartmentalised organisms, failure of their hydraulic transport system could differ between organs. We test here whether xylem tissue stems and roots in drought-induced embolism resistance, intact equally resistant to than root segments. Methods Embolism resistance stem was measured based on the pneumatic technique for Acer campestre , A. pseudoplatanus Corylus avellana comparing also segments C. . Moreover, we compared anatomical features such as interconduit pit membrane stems. Results found a higher stems, although significant difference only pseudoplatanus. Interconduit thickness similar both organs two species, but membranes were thicker Also, an network thick Conclusion Our observations show that is not more vulnerable xylem, species need be studied if this finding can generalised. demonstrated method applied non-terminal plant samples.
