Title: Information about Erigeron annuus and Erigeron philadelphicus
Answered by: Nan Hampton
QUESTION:
Hi! I am looking for information about the specific leaf area of Erigeron annuus and Erigeron philadelphicus. Do you know of anyone who is working with any these species, who might be able to provide this information? I have done an exhaustive literature search and can't find the information published anywhere. Thanks so much. LaurenANSWER:
If you are looking for leaf dimensions there are leaf descriptions from Flora of North America of Erigeron annuus and Erigeron philadelphicus that give leaf dimensions. You would then have to calculate the area. Here are several methods for doing that:
Surface Area of a Leaf Teacher Sheet from AAAS Science NetLinks.
Are you looking for information on calculations of the Leaf Area Index of Erigeron annuus (Daisy fleabane) and Erigeron philadelphicus (Philadelphia fleabane)? If so, I did find the following citations/abstracts of articles that might be useful to you:
Abstract of: Lee, Ho-Joon. 1992. Germanition (sic), shade toarance (sic) and community characteristics on Erigeron annuus L. in Cheju. Korean Journal of Ecology. 01/1992: 15(2).
If neither of these is what you're looking for, please send Mr. Smarty Plants another question with clarification.
