Prolonged irradiation at moderately high intensities is a requirement for anthocyanin synthesis in many plants. Action spectra for anthocyanin formation, however, are different for nearly every species examined (1, 5, 6, 7, 9). In general, a maximum is present between 400 and 500 mg (blue) or one between 400 and 500 m, and another between 600 and 800 myi (blue & red). In some species a second controlling photoreaction which requires brief irradiances at relatively low intensities is present (1, 6). The latter exhibits all the characteristics of phytochrome (4) with a promotive action on anthocyanin production by the red region of the spectrum (600-700 me) that is reversed by far red (700-800 miL). A somewhat more responsive and experimentally convenient plant than the species previously used was desired to facilitate work on anthocyanin and examination of the photoreactions involved. Sorghum seedlings attracted attention because of marked reddening of the plants at an early stage of growth. Preliminary experiments showed that seedlings of many varieties of sorghum produced a great deal of anthocyanin. The availability of large lots of seeds of Wheatland milo (Sorghum vulgare Pers.) prompted its selection for further studies, some results of which are described herein.
