Hormonal Regulation of Growth in Unfertilized Cotton Ovules

C. A. Beasley 1

1 Biology Department, University of California, Riverside 92502

Exogenous plant growth regulators can substitute for pollination, fertilization, and subsequent embryo development in cotton. Isolated, unfertilized, immature ovules enlarge in the presence of kinetin, and both enlarge and produce fibers in the presence of indoleacetic acid or gibberellic acid or both. An extract of germinating cotton pollen qualitatively mimics the effect of exogenous hormones.
