摘要：

Evidence for involvement of 2 non-photosynthetic pigments in photoinduction of anthocyanin biosynthesis in the roots and mesocotyls of Z. mays L. seedlings was presented. Short (5 min), low energy (4.5 .times. 103 J .cntdot. m-2) fluences of red light neither induced anthocyanin synthesis nor enhanced phenylalanine ammonia-lyase (PAL) activity in dark-grown maize seedlings. Little anthocyanin synthesis and no enhancement of PAL activity was induced by continuous far-red light. Continuous white or blue light induced both anthocyanin synthesis and enhanced PAL activity. Phytochrome alone apparently cannot induce anthocyanin synthesis in maize seedlings. A strong phytochrome mediation of white light induced pigment synthesis was demonstrated. This effect was not demonstrable with white light enhanced PAL activity, indicating that phytochrome controls another step in anthocyanin biosynthesis.
