外源植物生长调节剂可以替代棉花的授粉、受精和随后的胚胎发育。分离的、未受精的、未成熟的胚珠在激动素的存在下扩大，在吲哚乙酸或赤霉酸或两者都存在的情况下扩大并产生纤维。萌发中的棉花花粉提取物定性地模拟了外源激素的作用。
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.
