Root Growth Potential as an Indicator of Outplanting Performance: Problems and Perspectives

Root growth potential (RGP) tests have not always proven to be good predictors of outplanting performance under operational conditions. Problems include sample collection, handling, and storage; testing environment; root growth rating system; species differences; outplanting site conditions; and development of an accurate and precise prediction equation. Unless better prediction equations can be developed or threshold points defined, RGP tests should be used primarily as a test of seedling vitality, not relative vigor.
