[APWG] Fwd: [vnps-pot] research on effects of wisteria on seed germination

[steveyoung at aol.com]

 Listers, please see the following interesting research concept. If you have any information and/or suggestions, please share them with the lists and the copies on this message as they are not list subscribers.

I will note from my own personal observations at Long Branch Nature Center in Arlington, Virginia that dense Asian Wisteria growth there appears to suppress everything else (plus kill large trees to boot, over time). So this topic is of interest to me as well as I have wondered whether there is an allelopathic compound at work.

Cheers,

???? Steve

Dear VNPS-Potomac

My Biology classes have noted that underneath a huge population of Asiatic Wisteria adjacent to our school in Oakton VA there are almost no other species of plants.? A Biological Research student is trying to design a study to find out the effects of wisteria on germination of native seeds this semester (% germination, growth rate after germination).

She plans to study success in the field (comparing under wisteria cover and in wisteria free area of same woods) ?and in the controlled conditions in the lab?using soil from the above two places as well as commercial potting soil, and watering some with some sort of wisteria extracts, either from the roots, stems, or old leaves (no fresh leaves now). 

?

She is hoping for some advice on which species of Virginia native seeds she should use-- those woodland species (tree or herbacious) that are easy to obtain and easy to germinate.? Any ideas of what she species she should study and where she can get these seeds?? Any other advice to offer her?? Any other studies she should read? (By the way, Ash seedlings are common in other parts of this forest, though most of the ash trees now are devoid of seeds; they were feasted on in the fall by many house finches and purple finches.)

?

Thanks

Fred
