Mass, The Effects of Temperature and Daylength on the Flowering 



of Anemone Coronaria , Leam exactly whether temperature or day- 

 length factor causes Anemone coronaria to produce flowers 

 abundantly for a period and then become dormant. This knowledge 

 might help produce artificial conditions to make plant maintain 

 a consistent production of flowers over a longer period,
