Figure 1. Effects of orientation and initial stolon length on survival of fragments of Alternanthera philoxeroides.

Shaded bars (A) are grand means + s.e. of the five orientation treatments across the two stolon length treatments; open bars (B) are means + s.e. of the ten orientation and stolon length treatment combinations. Letters show which means differed within each measure (Student-Newman-Keuls test, P = 0.05).
