Abstract

In the Otways district, Vic., Eucalyptus obliqua exhibits a wide edaphic tolerance and evidence is presented for the existence of ecotypes in this region. A comparison of three populations from acidic loam, neutral sand and alkaline sand showed significant differences in yield response when grown under glasshouse conditions. A tall open- forest population, naturally occurring on fertile acidic loams (pH 4.6-5.2), showed a marked reduction in yield, was severely chlorotic and developed red and necrotic patches on leaves when grown on calcareous sands of pH 6.5 and 8.0. Open-forest and low open-forest populations native to the sands of pH 6.5 and 8.0 respectively also developed some chlorosis,..
