Field Survey of <I>Mycorrhiza</I> in Eucalypts and Pines

Abstract

Species of Eucalyptus possess mycorrhiza. Which is typically ectotrophic. Eucalypts are planted extensively in India. In this exotic home, no attempt is made to introduce mycorrhiza. However, Eucalyptus grandis and E. hybrid (probably E. tereticornis) planted extensively in South India usually developed mycorrhiza, which is likely to be useful to the eucalypts raised mostly in poor sites. Some species of exotic conifers are found to grow well in nurseries in South India. However, mycorrhiza is usually absent in them. Introduction of mycorrhiza appears necessary in order that the conifers may establish well when planted under forest conditions.
