Supplemental Lighting and Earliness of Flowering
In the previous article (July, 2003) we discussed how light intensity (irradiance) and supplemental lighting can affect flowering of seed-propagated bedding plants. This article is the second article to focus on the same topic and provides additional information on how the need for supplemental lighting varies in different parts of the country. In addition, how species differ in how much light they can use is presented. Lastly, how high day temperatures can affect photosynthetic rate and plant quality is discussed. Future articles will show new results on how day length affects flowering of many bedding plants.
