Dear Ecolog-Listers: I am trying to help a student germinate seeds of *Cercis canadensi*s, Eastern redbud. Our sources seem to indicate that a combination of removal of the seed coat (= scarification) on a solution of sulfuric acid for 30 minutes followed by storage in cold (= stratification) at 4 degrees Celsius for ca. 1 month yields highest germination. Has anyone tried this (or other method) recently and can confirm the success (or failure)?
If you wish to reply to me, please do so directly to my email: blayjo...@gmail.com Thank you. Sincerely, Jorge Jorge A. Santiago-Blay, PhD blaypublishers.com 1.
