  • Data are means ± se from 20 to 25 samples.

  • a Pith and fiber cells were from basal parts of inflorescence stems of 8-week-old plants.

  • b Eight-week-old plants were measured for stem height.

  • c Angles between cauline branches and main inflorescence stems were measured.

  • d Roots of 4-d-old light-grown seedlings were used for measurement.

  • e Hypocotyls of 4-d-old dark-grown seedlings were measured.
