Abstract
  • Small, single-point load cells were used to measure force exerted by the first leaf of three hard red cultivars (Farnum, Finley, and Norwest 553) as it emerged from a deep planting depth in a small containerized volume of soil. Coleoptile diameter was determined using a 0 to 25 mm, ratchet-stop 102-301 micrometer (Mitutoyo America Corporation; Aurora, Ill). Diameter measurements were made five mm above the base (CDB), in the middle (CDM), and five mm below the tip (CDT) of the coleoptile. Images of the tip of nine first leaves were made with a Quanta 600 reduced pressure scanning electron microscope (SEM) housed in the Linus Pauling Science Center at Oregon State University in Corvallis. Software in the SEM automatically computed the surface area of a subjective (operator-selected) segment of the tip of the first leaf.
