Plants grown (Capsicum frutescens, Salvia splendens, Lycopersicon pimpinellifolium, Lycopersicon esculentum) show some striking differences when compared with control plants grown under normal conditions. Some of these differences are: 1. Amount of vegetative foliage produced. 2. Size of vegetative shoots. 3. Rate of growth of vegetative shoots. 4. Thickness of stem. 5. Length of stem between nodes. 6. Date of flowering. 7. Number of flowers. 8. Number of flowers which absciss before maturing. 9. General growth habits of the structures under the different conditions.
