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.
外源植物生长调节剂可以替代棉花授粉、受精和随后的胚胎发育。在激动素的存在下，分离的、未受精的、未成熟的胚珠会增大，而在吲哚乙酸或赤霉素或两者的存在下，它们不仅会增大，还会产生纤维。萌发棉花粉的提取物在定性上模拟了外源激素的作用。
