Figure 4.

Drought response of shoot dry weights in the pipe experiment and days-to-wilt (DTW) in the pot experiment. The shoot dry weight for the 30-cm pipe and the relative ratios (RSW) for 70 and 100-cm pipes are shown in the cluster tree. Data for shoot dry weight, RSW, and DTW are shown as averages ± standard errors for the three trials. The five groups identified by the cluster analysis are indicated using different colors. Group I, magenta; Group II, yellow; Group III, green; and Group IV, blue; Group V, black. Stars indicate domesticated accessions.
