- Ray florets are much larger, with an 8-12 mm long, yellow, three-lobed, strap-shaped ligule surmounting a short corolla tube.
- Indeed, it has been noted that tyloses appeared to hinder, but not entirely block, the movement of radiolabelled amino acids in the xylem sap at the ligule of senescent leaves of Lolium temulentum.
- Hopi confers pigmentation to a wide variety of plant tissues, including pericarp, root, mesocotyl, and leaf blade in the seedling, midrib, ligule, leaf blade, and anthers in the mature plant.
- Stem height was defined as the length between insertion of the first adventitious roots and the top of the spike, and ligule height as the height of the ligule of the corresponding leaf.
