Photosynthesis involves biological energy transduction, the transformation of light energy into chemical energy, and photosensory pigments, which play an important role in the process. Phytochrome, a photosensory pigment, regulates plant growth and development. This chapter explores research works on light-induced seed germination and the role of phytochrome to regulate plant growth and development, including seed germination. Pioneering work by Hendricks and colleagues looked at photo-reversible phytochrome responses. The use of herbicides to control weeds and the adverse affects of weeds on the environment and public health are discussed. With the persistent use of herbicides, over time weeds have developed resistance, a resurgence, and eventual replacement. The evolution of herbicide-resistant weeds and the harmful effects of herbicides lead to the development of an integrated weed-management program. Plowing presents a simple and effective method of weed control. The emergence of nighttime plowing to control weeds and its limitations are also presented.Less
