| Abstract: | Dubautia reticulata grows in a mesic forest habitat in Hawaii and
has 13 pairs of chromosomes: The tissue elastic properties of this species are
intermediate relative to those of the dry scrub , 13-paired D. menziesii and the
mesic forest , 14-paired D. knudsenii. The tissue elastic modulus near full hydration
, for example, is 3.5 MPa in D. menziesii, 6.1 MPa in D. reticulata, and 18.2
MPa in D. knudsenii. As a result of its intermediate tissue elastic properties, D.
reticulata exhibits an intermediate capacity for maintaining high turgor pressures
as tissue water content decreases . These result s imply that tissue elastic properties
are significantly associated both with the habitat in which a Dubautia species
grows and with its diploid chromosome number. The latter association is presumably
indirect, with the difference in chromosome number serving as a marker
for other significant genomic differences. |
