Fig. 3. Ordination diagram for discriminant analysis using the P <0.05 chisquare subset; 21 cases were used to develop a model to discriminate among the 3 types of halophytes. Six predictor variables were entered: campesterol, β-sitosterol, stigmasterol, and the sum of Δ5 -, Δ7-and Δ0-STs. Eu – euhalophytes (n = 11), Re – recretophytes (n = 5), Ex – salt excluders (n = 5).
