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.

这些结果表明，所观测的早春短命植物具有典型的C3植物特征，相比其它类型的荒漠植物具有较高的单位叶面积P高T及低WUE，并且在生长发育过程中表现出很低的根／地上生物量比、较高的叶面积比和单位叶面积干重，说明它们具有相对高的生长速率，这与其生长发育节律相一致，反映了它们与准噶尔荒漠环境相适应的特点。

The percentage of total biomass allocated to roots was positively correlated with WUE for the seven investigated species （ r = 0.93, p 〈 0.01）. Results indicate that the species investigated are typical C3 plants. These spring ephemerals are characterized by higher Pn, Tr 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.
