Miscellaneous Plant Growth Regulators

Gibberellins, abscisic acid, and ethylene have long been recognized as phytohormones. Like all plant hormones, they participate in many processes, and work in concert with other hormones. Gibberellins are involved in stem elongation and mitosis, and can overcome dwarfism. These hormones also participate in seed germination, by inducing the production of the enzyme a-amylase that in turn digests endosperm into sugars. We offer gibberellic acid (A3) as both acid and salt, and a gibberellin mixture with more than 50% A4, as well as the antagonist ancymidol. Abscisic acid is a stress hormone, of great interest in the development of drought-resistant crops. We offer both isomers, as well as a mixture of isomers. Ethylene, best known for fruit ripening, is a gas, and thus unavailable as a chemical; the ethephon molecule penetrates tissues and decomposes into ethylene.

More recently discovered hormones include the plant steroids and the jasmonates. The brassinoloid steroids affect numerous growth and developmental processes, and also act as anti-stress agents. Plants make jasmonates in response to injury and help defend plants against insect attack. We offer two brassinosteroids and the new bikinin, an activator of plant steroid signaling.
