Variation in the Solasonine Content of Fruits of S. khasianum at Different Stages of Development in Lucknow

Solanum khasianum Clarke, grown during July 1968 to May 1969 at N.B.G. Lucknow shows the development of maximum solasonine content in fruits when the plants are 9 to 10 weeks old by which time fruits change the colour from green to yellow. There is a sharp decline in the Solasonine contents if the fruits are allowed to mature beyond the yellow colour stage. Observations on flower to fruit development have also been recorded.
