This directional growth can occur via a plant's response to a particular stimulus, such as light (phototropism), gravity (gravitropism), water, (hydrotropism), and physical contact (thigmotropism) plant growth and development are mediated by specific plant hormones and plant growth regulators (pgrs) (ross et al 1983. This essay describes the emergence of hormone herbicides from academic plant physi- ology research in america in the late 1930s and 1940s, attending especially to the role of interactions between university scientists, industrial concerns, and government (particu- larly agricultural) agencies the importance of an.
