The percentage of total biomass allocated to roots was positively correlated with WUE for the seven investigated species (r=0.93, p.01). Results indicate that the species investigated are typical C3 plants. These spring ephemerals are characterized by higher P T and lower WUE in comparison with other desert species. The unique biomass allocation of low root/aboveground biomass ratio, higher leaf area ratio, higher leaf mass per unit leaf area, and photosynthetic traits are involved in the physiological mechanisms that contributed to the rapid growth of desert spring ephemerals.
