Plant Spectra: Absorption and Action
- 299 Downloads
This chapter will discuss the information which can be obtained from spectral measurements of plant material. The interaction between light and matter is one of the few non-destructive methods of analysis available to the biological scientist. The spectral measurement of the light transmitted through objects affords a means of looking within those objects. Unfortunately, our prejudices about what is transparent and what is opaque have prevented the full use of these measurements. It is not generally realized that monochromatic light can be transmitted through whole apples, tomatoes, bean seeds, or peanuts and that many biochemical processes which involve light absorbing substances can thus be studied in the intact specimen. In vivo spectroscopy is a powerful method for biochemical research which has not been exploited to its fullest extent.
