Measurement of Seed Vigor for Loblolly and Slash Pines
Abstract:Seed vigor test results for loblolly and slash pines were compared to germination performance data, both in the laboratory and in nursery beds. Of all laboratory vigor tests, only tetrazolium staining and leachate conductivity could be correlated with germination. Laboratory percent germination and Peak Value (a measure of germination rate) provided good vigor estimates. Derivation of these parameters from germination models based on the Weibull function was no better than obtaining them from standard germination test data with frequent counts. Leachate conductivity measurments were very promising and should be used if time constraints do not allow a germination test. Forest Sci. 32:170-178.
