Downs, R. J.; And Others
A brief summary of the effects of light on plant germination, growth and development, including photoperiodism and pigment formation, introduces 18 experiments and demonstrations which illustrate aspects of these effects. Detailed procedures for each exercise are given, the expected results outlined, and possible sources of difficulty discussed. In addition to a general bibliography of 19 references, supplementary reading is suggested for each exercise. The apparatus required is simple, and the experiments are suitable for school or college use. (AL)
