摘要
Streptomycin and chloramphenicol inhibit the development of the photosynthetic apparatus and enhance anthocyanin synthesis in tomato (Lycopersicon esculentum, cv. ''Beefsteak'') and red cabbage (Brassica oleracea, cv. ''Red Acre'') seedlings. The 2 antibiotics do not affect the basic features of light-dependent anthocyanin formation: the relative effectiveness of different irradiance levels and of different spectral regions and the red-far red reversibility of the response are essentially the same in seedlings grown in water or in solution of the 2 antibiotics. The action of the 2 antibiotics on anthocyanin synthesis is probably independent of the action of light. The results provide further evidence that the role played by photosynthesis in high irradiance reaction anthocyanin synthesis of young seedlings is only a minor one, if at all.
