Evaluating The Myth Of Allelopathy In California Blue Gum Plantations, Kristen Marie Nelson
Evaluating The Myth Of Allelopathy In California Blue Gum Plantations, Kristen Marie Nelson
Master's Theses
It is widely accepted that allelopathy is not only significant, but more or less singular, in the inhibition of understory vegetation in California Eucalyptus globulus (blue gum) plantations. However, there is no published documentation of allelopathy by blue gums against California native species. Here, we present evidence that germination and early seedling growth of five California native species are not inhibited by chemical extracts of blue gum foliage, either at naturally-occurring or artificially concentrated levels. In the greenhouse, seeds were germinated in field-collected soil from mature blue gum plantations and the adjacent native, coastal scrub communities. In petri plates, seeds …
