  1. In each case range (min.–max.) and mean ± SD value is given. Measurement unit of tracheary elements length–width is in millimetre and vessel end wall is in micrometre. Italic font with double superscript shows longest and italic font with single superscript shows shortest tracheary elements of different plant parts of  the studied population
