Abstract
I HAVE found that pretreatment with citric acid increases both speed and total germination of eastern red cedar seed. Earlier, exploratory investigations showed that the acid also increased both speed and total germination of bald cypress seed (Taxodium distichum (L.) Rich) and I have reported similar effects of pretreatment of eastern white pine seed (Pinus strobus L.) with both citric and tartaric acids1. Of the several species examined, eastern red cedar showed the most striking response to pretreatment with citric acid.
